Abstract Two new species of Pulaeini, Lupaeus damavandiani Paktinat-Saeij & Castro sp. nov., and Pulaeus aryani Paktinat-Saeij & Castro sp. nov., are described and illustrated from soil, humus and moss in the Mazandaran province, Iran. Also, the status of two genera are considered. Eight new combinations are proposed, namely L. akbari (Bashir & Afzal, 2009) comb. nov., L. anjumi (Bashir & Afzal, 2007) comb. nov., L. ferventis (Taj & Chaudhri, 1990) comb. nov., L. haurio (Taj & Chaudhri, 1991) comb. nov., L. payatopalpus (Corpuz-Raros, 1996) comb. nov., L. stultus (Taj & Chaudhri, 1991) comb. nov., L. walii (Bashir & Afzal, 2009) comb. nov. and Neocunaxoides neopectinatus (Shiba, 1978) comb. nov. P. razanensis Den Heyer, 2013 syn. nov. considered a junior synonym of P. krama (Chaudhri, 1977). Lupaeus clarae (Den Heyer, 1981b) is reported for the first time from Iran. Keys to the Lupaeus and Pulaeus species of the world are provided. Key words: Bdelloidea; Cunaxoidinae; predatory mites; taxonomy; Mazandaran Province

Introduction Bdelloidea comprises a moderately large assemblage of predatory species grouped in two cosmopolitan families: Bdellidae and Cunaxidae. Many species of Cunaxidae are active on plant foliage and prey on phytophagous insects and mites. Cunaxoidinae (e.g. Pulaeus Den Heyer, 1980a, Lupaeus Castro & Den Heyer, 2009, Cunaxoides Baker & Hoffmann, 1948 and Neocunaxoides Smiley, 1975) are cruise predators that search out arthropod prey but also take less active forms such as nemathodes (Walter & Kaplan 1991). These mites have relatively short palpi that are held parallel to their chelicerae as they search for prey (Walter et al. 2009). Up to data, Lupaeus iranensis Den Heyer, 2013, L. lectus Catro & Den Heyer, 2009, L. lenis (Corpuz-Raros, 1996), L. martini (Den Heyer, 1981b), L. sativae Den Heyer, 2013, L. subterraneus (Berlese, 1916), L. valentinae Sergeyenko, 2011, Pulaeus glebulentus Den Heyer, 1980a, P. krama (Chaudhri, 1977) and P. pectinatus (Ewing, 1909) have been previously reported from Iran (Kamali et al. 2001; Akbari et al. 2010; Jalaeian et al. 2011; Beyzavi & Ostovan 2012; Den Heyer et al. 2013; Paktinat-Saeij et al. 2014). In this work, two new species, Lupaeus damavandiani sp. nov. and Pulaeus aryani sp. nov., are described and Lupaeus clarae (Den Heyer, 1981b) is reported as a new record from Iran. 778 © Systematic & Applied Acarology Society

Material and methods Samples of soil and leaf litter were taken from Mazandaran Province. Mites were extracted using a Berlese-Tullgren funnel and specimens were collected in AGA solution (Smiley 1992). Collected specimens were cleared in Nesbitt’s fluid, mounted in Hoyer’s medium (Walter & Krantz 2009), and examined under an interference contrast microscope (Nikon, Eclipse i80) and a phase contrast microscope (Leica, DMLB) at the Department of Plant Protection, University of Maragheh, Iran, and at the Department of Entomology and Acarology, Escola Superior de Agricultura “Luiz de Queiroz” (ESALQ)-Universidade de São Paulo (USP), Brazil. Illustrations were made with the aid of a drawing tube attached to the phase contrast microscope. Measurements were taken with a graded ocular. The length of gnathosoma was measured from the base to the tip of the subcapitulum, the length of the idiosoma from the suture between the gnathosoma and idiosoma to the posterior margin of the idiosoma, the width of the idiosoma at its broadest level and the legs from the ventral insertion of coxae to the base of the pretarsi. The setal nomenclature of Den Heyer & Castro (2008) is followed for the idiosoma except for the propodosomal setae, which follows the notation given by Fisher et al. (2011) and legs follows that of Den Heyer (1981a). The abbreviation of setal names are as follows: Prodorsal setae: anterior trichobothria (at), posterior trichobothria (pt), lateral proterosomal setae (lps), median proterosomal setae (mps). Hysterosomal setae: internal humerals (c1), external humerals (c2), internal dorsals (d1), internal lumbals (e1), internal sacrals (f1), external sacrals (f2), internal clunals (h1), external clunals (h2). Anal region: postanals (ps); genital region: aggenital setae (ag), genital setae (g). Hypognathal setae (hg). Leg setae: attenuate (sharply) solenidion (asl), bluntpointed rod-like solenidion (bsl), trichobothria (T), simple tactile seta (sts), macroseta (ms), duplex setae (dxs), setae between such brackets indicate duplex condition ({}), famulus (fam), dorsoterminal solenidion (dtsl), terminal solenidion (tsl). All measurements are given in micrometers (μm) for the holotype and paratypes (in parentheses).

Gnathosoma (Figs. 10–11). Gnathosoma similar to female. Subcapitulum 95 with four pairs of hg-setae, hg1 12, hg2 13, hg3 28 and hg4 8 and two pairs of adoral setae. Three-jointed palp (Fig. 10), 58. Chelicera (Fig. 11) 105 with cheliceral seta 5. Legs (Figs. 9, 12–15). The leg chaetotaxy differs from that of female as follows: tarsi I–IV, 3bsl, 1fam, 1dtsl, 2tsl, 20sts-1bsl, 1asl, 1dtsl, 1tsl, 16sts-1tsl, 13sts-14sts. Immature stages. Unknown. Remarks The new species resembles Lupaeus iranensis Den Heyer, 2013 and L. lectus Catro & Den Heyer, 2009 by having similar dorsal ornamentation and propodosomal coxal plate completely divided; however, it can be distinguished by having 1) six setae on basifemur II instead of five setae in L. lectus, 2) solenidotaxy of genua I–IV: 4-2-1-1 instead of 3-2-1-1 in L. iranensis and 4-2-1-2 in L. lectus; 3) genital seta g3 near outer margin on genital plate while in L. iranensis is arranged in a straight row. This new species is also very close to L. martini (Den Heyer, 1981b) and L. valentinae Sergeyenko, 2011, but differs from them by having: 1) one solenidion on genua IV (two solenidia in the other species); 2) dorsal shield with subcuticular punctations (smooth in the other species); 3) tarsus I with three solenidia (four solenidia in L. martini). Note Similarly to L. martini, the new species also has a striation pattern after the posteromedian region that resembles a small platelet, but it is not sclerotized and clearly defined as in Neocunaxoides rykei Den Heyer, 1980b. Although in the original description of L. martini is described as a small median platelet, we suggest it is similar to the ill-defined plate-like area present in L. damavandiani. Etymology The species is named in honor of Dr. Mohammad Reza Damavandian (Professor of Entomology, Sari Agricultural Sciences and Natural Resources University, Mazandaran, Iran), professor of the senior author in the graduate period. Type materials Holotype female, one paratype female and one paratype male were collected from samples of soil and rotten leaves under citrus trees, 20 May 2013, Osku-Mahalleh village, Amol city, Mazandaran province, Iran, by Saeid Paktinat-Saeij. The holotype female and one paratype male are deposited in the Acarological Collection, Department of Plant Protection, Faculty of Agriculture, University of Maragheh, Maragheh, Iran, and one paratype female is deposited in the Acarological Collection, Jalal Afshar Zoological Museum, Department of Plant Protection, Faculty of Agriculture, University of Tehran, Karaj, Iran.

Lupaeus clarae (Den Heyer, 1981b) Diagnosis Adult female of this species can be distinguished from other species of Lupaeus by the presence of a dorsal plate almost completely provided with broken striae except for the lateral edges which are smooth; with a small plate-like area between the posteromedian margins; the propodosomal coxal plate is not completely divided; solenidiotaxy of genua I–IV: 1dxs, 3asl-2asl-1asl-2asl. 2016

The propodosomal coxal plates completely divided medially; striations posteromedialy to coxae forming a small, ill-defined plate-like area. The integument bears one pair of propodogastral setae and three pairs of hysterogastral setae. One pair of paragenital setae occur anterolaterad of the genital valves. Genital valves with longitudinal rows of papillae; genital plate with four pairs of genital setae in almost straight longitudinal row. Setae g4 sort of longer than the other setae. g1 14, g2 11, g3 13, g4 16. Gnathosoma (Figs. 19–21). Subcapitulum 115 with four pairs of hg-setae, hg1 20, hg2 20, hg3 33 and hg4 ? and two pairs of adoral setae. The ventral surface of the subcapitulum with transverse lines posteriad setae hg4 (Fig. 19). The surface laterad and anteriad setae hg4 punctated. Threejointed palp (Fig. 20), 80. Surface of palps almost smooth, except proximal half of femorogenu covered by papillae. Trochanter without setae; femorogenu, 6 sts; tibiotarsus, 5 sts, one bladder like apophysis and one pointed process. Chelicera (Fig. 21), 127 with cheliceral seta 8. Legs (Figs. 18, 22–25). Leg chaetotaxy as follows: coxae I–IV, 1peg, 3-3-3-3 sts; trochanters I– IV, 1-1-2-1 sts; basifemora I–IV, 4-6-3-2 sts; telofemora I–IV, 5sts -5sts -3sts, 1ms-2sts, 1ms; genua I–IV, {1asl, 1sts}, 2asl, 4sts-1asl, 5sts-1asl, 5sts-1asl, 5sts; tibiae I–IV, 2asl, 5sts-1bsl, 5sts-1bsl, 5sts-1T, 4sts; tarsi I–IV, 3bsl, 1fam, 1dtsl, 2tsl, 19sts-1bsl, 1dtsl, 1tsl, 19sts-1tsl, 15sts-16sts. Adult male and immature stages and male. Unknown. Remarks This new species differs from other species of Pulaeus by having the dorsal idiosomal shield mostly smooth except an area between the pt and c2 which is broken striae. Despite it resembles P. semistriatus Sergeyenko, 2011 by also having propodosomal coxal plate completely divided and the 2016

same legs chaetotaxy, differs by having the dorsal idiosomal shield not like P. semistriatus, which is smooth in the anterior and broken striae in the posterior part. Etymology The epithet aryani refers to “Aryan”, the ancient spelling of the word "Iranian", which translates to noble in old Persian.

Type materials Holotype female collected from the soil and rotten leaves under citrus trees, 20 May 2013, OskuMahalleh village, Amol city, Mazandaran province, Iran, by Saeid Paktinat-Saeij. The holotype female is deposited in the Acarological Collection, Department of Plant Protection, Faculty of Agriculture, University of Maragheh, Maragheh, Iran.

Key to the world species of Pulaeus Den Heyer, 1980a (females) Note. Available information about P. parapatzuarensis (Shiba, 1978), P. pseudominutus (Shiba, 1978) and P. zaherii (El-Bishlawy & Rakha, 1983) is not sufficient to allow their inclusion in the key, despite the complementary information recently published by Skvarla et al. (2014). Also, P. cinctus (Chaudhri, 1980) can be distinguished by having a divided propodosomal coxal plate, lacks a median platelet between coxae II–III, setae f1 and f2 not located on sclerotized platelets or shields and having four pairs of setae on integument between coxal and genital plates. Pulaeus ranzanensis Den Heyer, 2013 was not included in this key because based on the available literature information no major differences could be observed between this species and Pulaeus krama (Chaudhri, Akbar & Rasool, 1979). Therefore, we suggest P. razanensis Den Heyer, 2013 syn. nov. is junior synonym of P. krama. In addition, Neocunaxoides neopectinatus (Shiba, 1978) comb. nov. described as Cunaxoides neopectinatus Shiba, 1978 was transferred to Pulaeus by Skvarla et al. (2014). In this paper we

consider it to belong to Neocunaxoides, because of the absence of f2; thus a new combination is now established for this species, Neocunaxoides neopectinatus (Shiba, 1978) comb. nov. 1 – 2 – 3 – 4 – 5 – 6 – 7 – 8 – 9 – 10 – 11 – 12 – 13 – 14 – 15 – 16 – 17 – 18 – 19 – 20 –
