Abstract The caprellidean fauna of Western Australia and Northern Territory, Australia, is investigated here. The study reports 26 species in 19 genera. Six new species (Aciconula australiensis n. sp., Caprella traudlae n. sp., Pseudaeginella vaderi n. sp., Orthoprotella nana n. sp., Pseudoprotella soela n. sp. and Pseudoprotomima grandimana n. sp.) are described as new for Science. Lateral view figures of all the species, together with a key to species level, are also provided.
Introduction Caprellid amphipods are small peracaridean crustaceans, important as secondary and tertiary producers in marine ecosystems. They are common and diverse on algae, hydroids, bryozoans, sponges, seagrasses (McCain, 1968) and are important prey for many coastal fish species (Caine, 1987, 1989, 1991). Recently, caprellids have been found to be useful bioindicators of marine pollution and environmental stress (Takeuchi et al., 2001; Guerra-García & GarcíaGómez, 2001), adding interest to understand the taxonomy and systematics of this group of crustaceans. The Caprellidea of the Western Australia and Northern Territory, Australia, have been scarcely studied. McCain & Steinberg (1970) in the ‘Crustaceorum Catalogus’ listed only 7 caprellid species recorded in Western Australia (Caprella equilibra Say, 1818, Hemiaegina minuta Mayer, 1890, Liriarchus perplexus Mayer, 1912, Metaprotella haswelliana (Mayer, 1882), M. sandalensis Mayer, 1898, Monoliropus agilis Mayer, 1903 and Orthoprotella australis (Haswell, 1880)), and no caprellids from Northern Territory were reported by these authors. After this revision of McCain & Steinberg (1970) no taxonomical studies on the Caprellidea have been carried out
along North-western Australia apart from the recent paper of Hirayama (1988) describing the genus Quadrisegmentum based on specimens of Q. triangulum Hirayama, 1988 collected from Ashmore Reef, Northwest Australia. Therefore, only 8 species have been recorded from Northwestern Australia before this study. Several collections of caprellid material from Western Australia and Northern Territory, Australia, collected by the Australian Museum staff (see Fig. 1 and Appendix), have been comprehensively studied in the present work. The examined specimens for this study are deposited in the instituions listed below: AM Australian Museum, Sydney TM Tasmanian Museum, Hobart USNM National Museum of Natural History, Smithsonian Institution, Washington D.C. ZMUC Zoological Museum, University of Copenhagen, Copenhagen GANM ‘Grigore Antipa’ National Museum of Natural History, Bucharest

Systematics account Taking into account that phylogeny and higher classification of the Caprellidea is still under debate, the genera have been grouped considering the smallest number of families, following Takeuchi (1993). Complete synonymies of the species can be found in McCain & Steinberg (1970). In this paper, we have only included the most relevant references. Figures of generalized caprellids including the morphological terms used in descriptive accounts are included (Figs 2– 5) to facilitate the understanding of the taxonomical description and the use of the key to species.

Material examined. 1 male, 1 female AM P48787 (TA1). Remarks. Caprellina longicollis has been recently redescribed in detail by Guerra-García (2002a) based on specimens from Chile. The specimens from Western Australia are in agreement with the redescription. In the material found in Western Australia (only two specimens in poor condition) pereopods were lacking so the illustrations included here are based on Tasmanian specimens recently collected (Guerra-García & Takeuchi, 2004). Habitat. Although McCain & Steinberg (1970) reported for the species a deep range between 0 and

29 m, McCain (1969) examined some material from 123 m deep. Caprellina longicollis have been recorded from algae, under rocks and attached to buoys (Guerra-García, 2002a).
Distribution. Type locality: Chile (Nicolet, 1849). Other records: South Africa, New Zealand (North and South Islands, Stewart Island, Brother Islands, The Snares, off Antipodes Islands, off Auckland Islands) (McCain & Steinberg, 1970), Tasmania (Guerra-

Remarks. The genus Dodecas comprised seven species of doubtful validity (Laubitz, 1991a): D. decacentrum Stebbing, 1910, D. elongata Stebbing, 1883, D. eltaninae McCain and Gray, 1971, D. grandimana Guiler, 1954, D. hexacentrum Mayer, 1903, D.
reducta Barnard, 1932 and D. tasmaniensis Guiler, 1954. Guiler (1954) synonymised D. decacentrum with D. hexacentrum. McCain & Steinberg (1970) and Laubitz (1991) remarked that D. grandimana and D. tasmaniensis appeared to be variants of D. hexa-

centrum. Laubitz (1991a) considered that D. eltaninae and D. reducta are synonymous with D. elongata. Taking into consideration all these synonymies, the genus would be only composed of two species, D. elongata and D. hexacentrum. Nevertheless, recently, Takeuchi (in prep.) considered D. hexacentrum and D. decacentrum as valid species on the basis of material collected from New South Wales. After examination of the types of D. tasmaniensis this species seems to be also a valid species. The material collected from Western Australia is very scarce (only two premature females) but the body spination and the gnathopod 2 are in agreement with the material described by Guiler (1954).
Habitat. Dodecas tasmaniensis has been found living on Caulerpa, sponges, bryozoans, red and brown algae and sand (Guerra-García & Takeuchi, 2004). In the present study the specimens were collected from sponges and scrapings from rock overhang. Distribution. Type locality: Off Mountain Creck, Tasmania. The two specimens examined in the present study were found in the south part of Western Australia. This species is distributed along southern Australia (Guerra-García, unpublished data) and Tasmania (Guiler, 1954; Guerra-García & Takeuchi, 2004). New record to Western Australia.

Hircella inermis Guerra-García & Takeuchi, 2004 (Fig. 8) Hircella inermis Guerra-García & Takeuchi, 2004: 975–982, Figs 4–8. Material examined. 2 males, 2 females AM P62052 (WA-117); 1 female AM P62053 (WA-220); 1 male AM P 62051 (WA-296). Type material (deposited in
the Australian Museum): holotype male (AM P48776) (Fig. 8a) collected from Whalers Cove, Tasmania, by G. Edgar, 30 June 1993, 5 m deep. Allotype female (AM P48815) (Fig. 8b) collected from Cementary Bluff, Tasmania, by I. Takeuchi & G. Edgar, 4 April 1996, 3 m deep. Paratypes (AM P61390): 4 males, 2 females collected together with the allotype.
10 Remarks. This species has been recently described based on material collected from Tasmania by GuerraGarcía & Takeuchi (2004) and the lateral view of the type specimens are included in the present paper (Fig. 8). Mayer (1882) established the genus Hircella mainly on the basis of the absence of pereopod 5. The genus Liriarchus Mayer, 1912 is also characterised by the absence of pereopod 5 in males or extremely reduced in females. However, Hircella and Liriarchus can be differentiated by the abdomen: there are two pairs of appendages in Hircella and only one pair in Liriarchus. The number of articles of antenna 2 varies among the adult specimens of Hircella inermis, being two or three. Habitat. Hircella inermis has been found in very shallow waters, clinging to the brown algae Sargassum spp and Acrocarpia sp and the red alga Plocamium angustum Agardh, 1863 (Guerra-García & Takeuchi, 2004). In the present study the specimens has been collected from red algae, weed mat from intertidal areas and Posidonia beds. Distribution. Type locality: Whalers Cove (43◦ 17 S 148◦ 00 E), Tasmania, Australia (Guerra-García & Takeuchi, 2004). Similarly to D. tasmaniensis, this species were only found in the south area of Western Australia during the present study, distributing along South Australia (Guerra-García, unpublished data) and Tasmania (Guerra-García & Takeuchi, 2004). New record to Western Australia. Liriarchus perplexus Mayer, 1912 (Fig. 9) Liriarchus perplexus Mayer, 1912: 6–8, Figs 1–2. Material examined. 1 female AM P62044 (WA181); >20 specimens AM P62043 (WA-202); 2 females AM P62045 (WA-220); 1 male and two females AM P62042 (WA-260). Remarks. This is the first record of this species after the original description of Mayer (1912) based on specimens collected from Champion Bay and Cockburn Sound, Western Australia. The species resembles superficially Hircella inermis but can be easily distinguished by the abdomen (see remarks for Hircella inermis). Habitat. The species has been found clinging on green and brown algae, red algae with epiphitic
hydroids and bryozoans and along Posidonia beds (present study). Distribution. Type locality: Champion Bay and Cockburn Sound, Australia, 3.5–8 m. Only known from Western Australia so far (Mayer, 1912). Metaproto novaehollandiae (Haswell, 1880) (Fig. 10) Proto novae-hollandiae Haswell, 1880: 275-276, pl. 2, Fig. 3; Mayer, 1882: 26; Stebbing, 1888: 1230– 1232; Mayer 1890: 14–15. Metaproto novaehollandiae Mayer, 1903: 26–27, pl. 1, Figs 11–12, pl. 6, Figs 24–28, pl. 9, Figs 3, 50; Stebbing, 1910: 651–652; McCain & Steinberg, 1970: 56; Laubitz 1991b: 103–104, Fig. 1. Material examined. 1 female AM P61940 (NT-22); 2 males AM P61941 (NT-30); 1 female AM P62061 (04 B12). Remarks. The specimens examined in the present study are in agreement with those described by Haswell (1880) and redescribed by Mayer (1903) and Laubitz (1991b) and with specimens collected from Philippines, Papua New Guinea and Queensland, examined by the author. This species is fully redescribed based on specimens collected from New South Wales, close to the type locality (Takeuchi, in prep.). Taking into account that the specimens from Northern Territory were not complete and pereopods were lacking we have included here lateral view figures based on specimens collected from Queensland, Australia, which were in better condition and can be more useful for readers when using the key. Habitat. Metaproto novaehollandiae has been found from intertidal areas to 790 m deep (Laubitz, 1991b). This species shows a clear preference by soft bottoms (fine sediments and sand) (Guerra-García, in rev.). In the present study, the species has been found in sand but also on hydroids and small tunicates. Distribution. Type locality: Port Jackson, New South Wales, Australia (Haswell, 1880). Other records: Banda Sea, Indonesia, South Africa (McCain & Steinberg, 1970), New Caledonia and Philippines (Laubitz, 1991b), Papua New Guinea and Queensland (Guerra-García, in rev.). New record for Western Australia and Northern Territory, Australia.

13 types (AM P61283): 2 females, 5 juveniles collected together with the holotype. Remarks. The genus Paraproto, restricted so far to Australian waters, is composed of four species: Paraproto condylata (Haswell, 1885), Paraproto gabrieli Stebbing, 1914 Paraproto spinosa (Haswell, 1885) and Paraproto tasmaniensis Guerra-García & Takeuchi, 2004. Paraproto tasmaniensis is close to Paraproto condylata. The type material of P. condylata described by Haswell (1885) as Proto condylata is missing (Springthorpe & Lowry, 1994) but a detailed redescription of specimens of Paraproto from Antarctica is included in Guerra-García & Coleman (2001). Habitat. Paraproto tasmaniensis has been found clinging to brown algae (such as Acrocarpia sp., Perithalia sp. and Sargassum sp.) and red algae (Plocamium angustum J. Agardh, 1863, P. dilatatum J. Agardh, 1863, and Zonaria sp.) between 3–30 m deep (Guerra-García & Takeuchi, 2004). The species has also been found in Caulerpa, sea grass and tunicates (present study). Distribution. Type locality: Armstrong Channel, Cape Barren Island (40◦ 30 S 148◦ 08 E), Tasmania, Australia (Guerra-García & Takeuchi, 2004). New record to Western Australia. Similarly to Dodecas tasmaniensis and Hircella inermis, this species has been found only in the stations of southern Western Australia, being biogeographically restricted, so far endemic, to waters of southern Australia and Tasmania.
based on specimens collected from Tanzanian waters. The specimens studied from Western Australia are in agreement with those collected in previous studies. Guerra-García (2002a) pointed out that probably Pseudocaprellina pambanensis should be transferred to the genus Caprellina. Both genera can be differentiated by the number of articles of the flagellum of antenna 2 (two in Pseudocaprellina and three in Caprellina). Nevertheless, the number of articles of antenna 2 varies among the adult specimens of some species, as Hircella inermis, indicating that the number of articles in antenna 2 should not, consequently, be considered as an important morphological character to differentiate species or genera. In any case, the phylogenetic relations among the species of the close genera Caprellina, Pseudocaprellina, Hircella and Liriarchus should be studied. There is a continuous gradient of variation in the characters of the species belonging to these genera, which makes difficult the delimitation and diagnosis of valid genera. Habitat. The species has been collected previously from algae between corals (Guerra-García, 2002b). The specimens studied in the present work were clinging to intertidal algal mat and bottoms with Posidonia australis (Hooker, 1858). Distribution. Type locality: Gulf of Mannar, India (McCain & Steinberg, 1970). Other records: Tanzanian coasts (Guerra-García, 2002b). New record to Australia. The species, being found in India, Tanzania and Western Australia, is probably distributed throughout the Indian Ocean. Pseudoproto fallax Mayer, 1903 (Fig. 13)

Flagellum of antenna 1 with four articles (Fig. 14B). Gnathopod 2 inserted in the anterior half of pereonite 2; merus rounded; carpus not elongate; propodus without distal projections. Oosteguites not setose (Fig. 14B). Pereopods 3 and 4 propodus without grasping spines (Figs 17C, D). Abdominal appendages 1-articulate (Fig. 18D). Remarks. The genus Pseudoprotomima was originally established with hesitation, since it differs from Protomima Mayer, 1903 only in that the pereopod 5 is 6-articulate in Pseudoprotomima and 5-articulate in Protomima. The type species of the genus, P. hurleyi, was described by McCain (1969) based on specimens collected from New Zealand. McCain & Gray (1971) described P. hedgpethi from SubAntarctic waters. Therefore the genus Pseudoprotomima is constituted by three species so far, which are compared in the Table 1. Pseudoprotomima grandimana differs from the remaining two species in the genus mainly in the feature of the gnathopod 2 with a long basis and the propodus palm carrying large projections distally. The smaller size of the body and number of articles of the antenna 1 flagellum, together with the preference for shallow waters are also different between P. grandimana and the rest of the species. Habitat. The specimens have been found from 3–18 meters deep, living on Caulerpa, Posidonia, Ecklonia beds and spirorbids. Distribution.

pereonite 3 in the male from Queesland (see serrate margin proximally of pereonite 3, Fig. 19B) could be due to different degree of development. The genus Aciconula was erected by Mayer (1903) on the basis of two female specimens of Aciconula miranda Mayer,
1903 collected from Singapore, Malaysia and Koh Krau, Thailand. After this, Mayer (1912) described the male of A. miranda based on material collected from Shark Bay, Australia. Chess (1989) described Aciconula acanthosoma Chess, 1989 which differs
29 from A. miranda mainly by the presence of abundant acute projections dorsally on the head and body. Consequently two species of Aciconula had been described before the present work, A. miranda and A. acanthosoma. The new species Aciconula australiensis is closer to A. miranda; the type material of A. miranda has been consulted for comparison. Of the two female types reported by Mayer, only one female have been located in the Zoological Museum of Copenhagen (ZMUC CRU-7341). Females of A. australiensis are very similar to the type of A. miranda but in A. australiensis the distal (fourth) article of the pereopod 3 is well-developed while it is tiny and almost not tabicated in A. miranda. Furthermore the inner lobes of the lower lip are bilobed in A. australiensis whereas they are simple (not bilobed) in A. miranda. Mayer (1912) in the description of the male of A. miranda did not report the presence of abdominal appendages. Nevertheless, Chess (1989) described a pair of well developed appendages in A. acanthosoma, and Takeuchi (1993) assumed this character (presence of appendages in male abdomen) as diagnostic for the genus based on the paper of Chess (1989). Males of A. australiensis lack abdominal appendages, which are degenerated into a group of setae. Aciconula miranda and A. australiensis present sexual dimorphism affecting the number of articles of pereopod 3, being this pereopod two-articulate in males and four-articulate in females. In A. acanthosoma, however, the pereopod 3 and 4 are 2-articulate both in males and females. Taking into account the presence of abdominal appendages in A. acanthosoma, and the feature of the inner lobe of maxilliped (clearly different from the other two species of Aciconula) the species A. acanthosoma could be transferred to a different genus. However, the remaining generic characters, specially the morphology of the pereopod 5 agree with Aciconula so we have maintained A. acanthosoma in the genus Aciconula at the moment. Habitat. The specimens collected from Western Australia were recorded from coral with encrusting bivalve molluscs. The specimens found in Lizard Island, Great Barrier Reef, Queensland, were clinging on small hydroids and algal turf associated to dead coral (Guerra-García, in rev.). Distribution.

Caprella inermis Haswell, 1879: 319–351. Material examined. 1 premature female AM P62013 (WA-117); 1 male AM P62008 (WA-223); 6 males AM P62014 (WA-277); 7 males, 4 mature females, 2 premature females, 1 juvenile AM P62009 (WA-472); 3 males, 1 mature female, 1 inmature female, 3 juveniles AM P62010 (WA-448); 1 female AM P62012 (WA-478); 2 females, 4 juveniles AM P61241 (TA1). Remarks. The present specimens of Caprella danilevskii collected from Western Australia are in agreement with those described by Krap-Schickel (1993) and figured by Guerra-García & Takeuchi (2002) from the Mediterranean. The general feature of the body, the distinctive male abdomen with a pair of appendages hooked distally, the absence of grasping spines in the pereopods and the short dactylus of male gnathopod 2 can be used to distinguish this species from the remaining Caprella species. Caprella danilevskii is one of the most-well studied caprellid species regarding to the life history based on Japanese specimens (Takeuchi & Hirano, 1991). Habitat. The species has been found in Cystoseira, Sargasum, amongst Bugula (Krapp-Schickel, 1993). Guerra-García (2001a) in an ecological study along the coast of Ceuta, north Africa, collected specimens from different species of algae (Asparagopsis armata Harvey, 1855, Cladostephus spongiosus Lyngbye, 1819, Cystoseira usneoides (L.) Roberts, 1967, Gelidium latifolium Bornet & Thuret, Halopteris scoparia (L.) Sauvageau, 1907, Sphaerococcus coronopifolius Stackhouse, 1797), in areas of high hydrodynamism. The specimens of the present study were found in brown algae, seagrass as Posidonia, sponges and tunicates. Distribution. Type locality: Black Sea (McCain & Steinberg, 1970). Caprella danilevskii is a cosmopol-
30 itan species (Krapp-Schickel, 1993). New record for Western Australia.

Material examined. 5 males, 3 females AM P62015 (WA-277); 4 males, 3 mature females, 3 premature females, 2 juveniles AM P62016 (WA-283); 1 male, 1 female AM P62018 (WA-197); 1 male AM P62018 (WA-454); 1 male, 1 juvenile AM P62019 (WA-287); >20 specimens AM P62020 (WA-276). Remarks. The specimens of C. equilibra present a distinctive ventral projection between the gnathopods 2 which can be used for differentiating this species from the another Caprella species found in Western Australia. The morphology of the present specimens examined here is in agreement with the description and figures of Krapp-Schickel (1993) based on Mediterranean specimens. Habitat. Caprella equilibra has been found from intertidal areas to 3000 m deep (Schellenberg, 1926) and does not present substrate preferences, clinging on seaweeds, bryozoans, sponges and ascidians (KrappSchickel, 1993; present study). In the North Pacific, this species is usually associated with artificial constructions such as aqualculture nets, water duct pipes and power plants, and floating docks (Takeuchi, 1995). Takeuchi & Sawamoto (1998) pointed out the dominance of C. equilibra in planktonic samples, indicating the possibility that C. equilibra has a greater tolerance for longer periods of planktonic dispersal than other caprellid species. Distribution. Type locality: South Carolina. Caprella equilibra is a cosmopolitan species (McCain, 1968; Krapp-Schickel, 1993).

Remarks. Caprella penantis has been recorded under several species or subspecies names from the temperate regions of the world and there is need of further studies to determinate its nomenclatural status at each locality (McCain, 1968; Laubitz, 1972; Takeuchi & Hirano, 1995). Habitat. The species has been found living on red and brown algae, Posidonia, hydroids, Alcyonaria, Zoantharia, Bryozoa, sponges, Arbacia (Echinodermata) and Libinia (Decapoda) (Krapp-Schickel, 1993). Guerra-García (2001a) found the species in intertidal exposed areas and in infralittoral areas of high hydrodynamics, clinging on different species of algae (Asparagopsis armata Harvey, 1855, Cladostephus spongiosus Lyngbye, 1819, Cystoseira tamariscifolia (Hudson) Papenfuss, 1950, Gelidium sesquipedale (Clemente) Bornet & Thuret, 1876, Halopteris scoparia (L.) Sauvageau, 1907, Laurencia pinnatifida (Gmelin) Lamouroux, 1813, Zonaria flava (Clemente) Agardh) and hydroids (Gymnangium montagui (Billard, 1912) and Sertularella gayi gayi (Lamouroux, 1821). The present specimens have been found in sponges, ascidians, spirorbids, gorgonaceans and Caulerpa beds. Distribution. Type locality: Devonshire Coast, England. Cosmopolitan species (Krapp-Schickel, 1993). New record for Western Australia.

scaura f. typica, diceros and cornuta (1890) and Utinomi’s C. scaura f. hamata do not bear a ventral projection between the insertion of gnathopod 2 as do Mayer’s varieties californica (1890), scauroides (1903) and spinirostris (1890). Dougherty & Steinberg (1953) separated C. scaura f. californica as another different species, Caprella californica, and Laubitz (1970) assigned to this species the two remaining varieties scauroides and spinirostris. The specimens collected from Western Australia have been identified as C. scaura on the basis of the absence of the ventral projection between gnathopods 2.
Habitat. Caprella scaura has been recorded from bryozoans, like Bugula neritina and Scrupocellaria, from the algae Sargassum spp and Cystoseira spp and the seagrass Halodule uninervis (Forsk.) Archers, and Halophila ovalis (R. Br.) Hook (Lim & Alexander, 1986). Takeuchi & Hino (1997) collected the species clinging on the seagrass Zostera marina Linnaeus, and Z. caulescens Miki, and Serejo (1998) found C. scaura clinging on the sponge Dysidea fragilis (Montagu, 1818). Guerra-García & Thiel (2001) found the species living on Bugula neritina (Linnaeus, 1758), on the seaweed Polysiphonia spp and Gracilaria spp
33 and the seagrass Heterozostera tasmanica (Martens ex Aschers). The specimens studied here were found in Posidonia australis, Caulerpa and spirorbids. This species present parental care (Lim & Alexander, 1986; Aoki, 1999). Distribution. Type locality: Riviere Noire, Mauritius (McCain & Steinberg, 1970). Caprella scaura has a wide distribution along the world, being cosmopolitan (McCain, 1968; Guerra-García & Thiel, 2001). New record to Western Australia. Caprella traudlae n.sp.

Maxilliped (Fig. 29C) inner plate oval carrying two nodular, short and roundsetae distally, together with three simple setae and a plumose setae; outer plate
rectangular, twice as long as the inner plate, with six setae; palp 4-articulate, distal article triangular, with rows of setulae. Antennae. Antenna 1 (Fig. 30A) as long as cephalon and pereonite 2 combined; flagellum sevenarticulate. Antenna 2 (Fig. 30B) almost 3/4 as long as antenna 1; swimming setae absent; flagellum twoarticulate, rectangular carrying robust setae minutely denticulate. Gnathopods.

Abdomen with a pair of uniarticulate, small, triangular appendages, a pair of lateral lobes and a single dorsal lobe (Fig. 31E). Remarks. The new species is close to Caprella danilevskii Czerniavskii, 1868 in the general shape of the body. Nevertheless, constant differences in gnathopod 2, pereopods and abdomen indicate that the present specimens belong to a different species, herein described as Caprella traudlae. Caprella danilevkskii and C. traudlae can be distinguished mainly on the basis of the following characteristics: (1) the gnatho-

ally have no abdominal appendages and traditionally, the presence of a pair of abdominal appendages in the female had been treated as diagnostic character of the genus Metacaprella Mayer, 1903. Some Caprella species as C. anomala, C. horrida and C. kernnerlyi had been considered inside the genus Metacaprella (Laubitz, 1972) on the basis of this character until Mori (1999) pointed out that the morphology of the
abdominal appendages changes ontogenetically, being a polymorphic and symplesiomorphic character in Caprella and Metacaprella. Therefore he synonimied both genera, becoming Metacaprella a junior synonymous of Caprella. Caprella traudlae is also close ot C. subinermis Mayer, 1890 and C. tsugarensis Utinomi, 1947 but it can be easily distinguised by the elongate basis and

The species have been found clinging on Posidonia beds. The elongate shape of the body, the long pereopods and the morphology of gnathopods 2 could be useful for the species to attach the seagrass in this type of marine habitat. Distribution.

tion of McCain (1968) based on specimens of the West coast of North America. Habitat. Hemiaegina minuta is widely distributed in tropical and temperate waters of the world oceans (McCain, 1968). Müller (1990) found H. minuta in more or less exposed reef locations. This species has been reported from Sargassum sp and plankton towls (McCain, 1968) and dead corals (Müller, 1990). The specimens studied in the present work have been found living on many different substrates: green algae as Halimeda spp, brown algae, red algae, sponges, tunicates, Posidonia, tunicates, dead corals encrusted with algal turf and under small boulders.

Remarks. This species has been recently redescribed in detail by Müller (1990). Metaprotella sandalensis is very common in shallow waters of the tropical IndoPacific Ocean (Müller, 1990) and it is the most common and abundant species along the studied area. The present specimens have been assigned to the species Metaprotella sandalensis on the basis of dorsal projections’ arrangement and the absence of a marked suture between head and pereonite 1 (Larsen, 1997). Although Müller (1990) pointed out the existence of a great deal of intraspecific variation, we can not discard the existence of a complex of different species. Further genetic studies are necessary to investigate if the variation among specimens is intra or interspecific. Habitat. Müller (1990) reported that the species probably prefers not very exposed locations. GuerraGarcía (in rev.) found that the species were the most common inhabitant of the Great Barrier Reef, Australia, living on many different habitats and substrates (algae, seagrass, sponges, hydroids, gorgonians, soft corals, dead corals encrusted, bryozoans, ascidians, coral rubble, coarse and fine sediments and mangroves). In the present study M. sandalensis was also found in a wide range of substrates.

Material examined. 2 males, 1 premature AM P62132 (WA-193). Type material (deposited in the Australian Museum): Holotype male (AM P61246) (Fig. 40a) collected from Breaksea Island, Port Davey, Tasmania by G. Edgar, 16 February 1989, 8 m, allotype female (AM P61247) (Fig. 40b) collected from Off Hannant’s Bight, cape Sorell by R. T. Springthorpe and P. M. Berents, 27 April 1991, 16 m, paratypes (AM P61391-2) (2 males, 4 females collected together the holotype and one female collected together the allotype).
53 Paradeutella sp. (Fig. 41) Material examined. 5 males, 2 females AM P62056 (WA-220); 2 males, 2 females, 1 juvenile AM P62054 (WA-472); 3 males AM P62055 (WA-478). Remarks. This species is very close to Paradeutella tanzaniensis Guerra-García, 2001. The type material of P. tanzaniensis (holotype male), collected from Tanzania and deposited in the ‘Grigore Antipa’ National Museum of Natural History, Bucharest (GANM AMP 328), have been checked for comparison.. Although the specimens from Western Australia are very similar to the the holotype of P. tanzaniensis, they have lateral projections in the pereonites 2 and 3, which are lacking in the material from Tanzania (GuerraGarcía, 2001b). Since a detailed revision of the genus Paradeutella is still lacking, the present specimens have been identified as Paradeutella sp at the moment. Habitat. The species has been found in shallow waters clinging on Posidonia and brown algae (present study). Distribution. Western Australia. Protella similis Mayer, 1903 (Fig. 42)

Remarks. This species has been recently described based on specimens collected from Tasmanian coasts (Guerra-García & Takeuchi, 2004). As other species, like Paraproto tasmaniensis, Hircella inermis and Dodecas tasmaniensis, Orthoprotella tuberculata has been only found during the present study in the southern area of Western Australia, being endemic so far, to the temperate southern Western Australia, South Australia, Victoria and Tasmania. Habitat. Orthoprotella tuberculata had been previously found living on red algae, bryozoan and sponges (Guerra-García & Takeuchi, 2004). Distribution. Tasmania (Guerra-García & Takeuchi, 2004). New record for Western Australia.

Allotype female AM P62133 (NT-48). Paratypes: 7 males, 4 females AM P62134 (NT-48); 1 male USNM 1009936 collected together with the holotype. Etymology. The species is dedicated to Prof. Wim Vader for his important contribution to the knowledge of amphipodean crustaceans. Description
Material examined. 1 male AM P62131 (WA-296); type material (National Museum of Natural History, Smithsonian Institution): male holotype (USNM 120179), female allotype (USNM 120180), 6 males paratypes (USNM 120183-86, 88), 3 females paratypes (USNM 120182-87). Remarks. The material examined in the present paper is very limited (only a single specimens without pereopods) but, after consulting the type material, we have assigned the specimen to Pseudaeginella biscaynensis on the basis of the general body feature, the absence of molar and the very reduced pereopods 3 and 4. Nevertheless, there is no lateral projections on the body surface of the specimen from Western Australia. This small difference could be attributed to intraspecific variation. McCain (1968) pointed out that the degree of spination of the pereonites varied considerably among the specimens.Specimens from Tanzania has been recently redescribed and figured in detail by the author (Guerra-García, 2002b). Habitat. The species has been found in shallow waters living on red algae (Mc Cain, 1968; present study), the green algae Avrainvillea sp. and the sea

Gnathopod 2 (Fig. 46E) inserted on the anterior part of pereonite 2; basis without distal projection; propodus oval without the round proximal projection near the grasping spine. Abdomen lateral lobes without setae (Fig. 47F). Remarks. The specimen selected as holotype male and one male paratype were collected during the Anton Bruun Expedition from the east coast of Africa, but additional material (allotype female and the remaining paratypes) were collected from Northern Ter-
ritory, Australia. Both group of specimens share the same morphological characteristics. The African specimen was selected as the holotype since it was in better condition than the Australian specimens. Six species of Pseudaeginella were known up to know, P. antiguae Barnard, 1932 from Antigua, P . biscaynensis (McCain, 1968) from Florida, P. montoucheti Quitete, 1971 from Brasil, P. polynesica Müller, 1990 which has been fully described and illustrated based on specimens collected from Bora Bora and Moorea, Society Islands and P.campbellae Guerra-García, 2003 collected from Subantarctic waters. Recently, after examination of specimens of Pseudaeginella tristanensis from Southern Indian Ocean, Laubitz (1995) considered the genus Fallotritella synonymous with Pseudaeginella mainly based on the presence of minute pereopods 3 and 4 also in Pseudaeginella. The species of Pseudaeginella are compared in Laubitz (1995). Pseudaeginella vaderi n. sp can be distinguished from the remaining species mainly by the striking male gnathopod 2, the absence of dorsal projection along the body and the bilobed inner lobes of lower lip. Habitat. The specimens collected from the Northern Territory were found clinging on brown algae. Distribution. East Coast of Africa. Northern Territory, Australia. Probably the species is distributed along the whole Indian Ocean. Pseudoprotella soela n.sp. (Figs. 48–51) Type material. Holotype female AM P62135 (04 B14).

propodus as long as the basis; palm provided with one grasping spine proximally, followed by setae and U-notch; dactylus elongate Pereopods. Pereopods 3 and 4 reduced, subequal (Figs 51A, B) twice as long as gills, two-articulate; proximal article with nine setae; distal article small, about 1/6 as long as proximal article, carrying two long simple setae and one shorter plumose setase. Pereopod 5, 6 and 7 missing in all specimens examined. Abdomen (Fig. 51C) with a pair of lobes carrying a simple setae and a single dorsal lobe with two short and plumose setae. Remarks. The seven examined specimens are females and no males have been found in the collections. In spite of the absence of male available for the description, and that the pereopods 5–7 are lacking in all females examined, the specimens have been assigned to a new species of Pseudoprotella. Al-
though the morphology of the antennae is closer to the genus Paradeutella, the present specimens have been assigned to Pseudoprotella on the basis of the following characters: pereonites 3 and 4 biarticulate, abdomen without appendages, mandibular palp with the setal formula 2-x-1, outer lobe of maxilla 1 provided with five stout setae, and mandibular molar present. The genus Pseudoprotella was, so far, constituted by three species, P. phasma (Montagu, 1804), P.inermis Chevreux, 1927 and P. bogisa (Mayer, 1903) recently transferred to the genus Pseudoprotella from the genus Noculacia (Guerra-García, 2002c). Guerra-García & Takeuchi (2000) redescribed P. inermis based on specimens collected from Ceuta, North Africa and compared morphologically P. inermis and P. phasma. Pseudoprotella soela n. sp. is closer to P. phasma by having dorsal acute projections on cephalon and pereonite 2. Nevertheless, both species can be distinguished mainly on the basis of the following characteristics: (1) P. soela present a pair of anterolat-
64 eral projections and a pair of dorsal round projections on pereonite 3, which are lacking in P. phasma; (2) the antennae are more setose in P. soela than in P. phasma; (3) although the pereonites 3 and 4 are two-articulate in both species, the structure is different: in P. soela the proximal article is the largest being the distal one very reduced while in P. phasma the proximal article is shorter and the distal one is the largest; (4) the inner lobes of the lower lip are bilobed in P.soela and simple in P. phasma. Habitat. All the specimens were collected with a sled dredge from 39–83 m deep. Distribution. So far, the species is only know from the type locality, North-West Shelf, Western Australia, Australia.
