Introduction This paper is part of a series (MORAVEC 2012) that aims to make important taxonomic and nomenclatorial results available before the completion of a final comprehensive publication, currently in preparation, which will provide a thorough revision of the Neotropical genera of the subtribe Odontochilina W. Horn, 1899 in a new sense. The new genus Brzoskaicheila gen.nov. is related to the genus Pentacomia Bates, 1872, but is clearly distinguished from all four currently-known subgenera of Pentacomia by a complex of characters, including the unique setation of the dorsal body surface, particularly elytra densely echinate-setose throughout their length. The infrageneric subdivision and the generic delimitation of the Neotropical genera Pentacomia Bates, 1872, Odontocheila Laporte de Castelnau, 1834, Cenothyla, Rivalier, 1969, Phyllodroma Lacordaire, 1843 and others, proposed by RIVALIER (1971), has been commonly accepted, as well as a wide concept of the subtribe Prothymina sensu RIVALIER (1969, 1971). In such a broad classification, which also includes the Neotropical genera mentioned above, RIVALIER (1969, 1971) characterized the subtribe Prothymina in terms of the tetra-setose labrum in combination with entirely glabrous thoracic and abdominal sterna. However, this ignores the fact that many Pentacomia species and several species of Odontocheila possess setal vesture, developed to a greater or lesser extent, in the form 35

of setose lateral thoracic portions, ventral thoracic sterna, ventrites, or even dorsal body surface; some of them also exhibit sparsely setose pronotum and densely clustered setae on the juxtaepipleural area. The new genus described here is one of the examples that, through its distinctly developed setal vesture, renders inappropriate the wider concept of the subtribe Prothymina W. Horn, 1910 sensu RIVALIER (1969, 1971). Therefore, as indicated by MORAVEC (2012), the subtribe Odontochilina should be restored and newly defined for only the Neotropical genera. Naturally, a final classification remains to be proposed in the concluding publication after comprehensive revision.

Material and methods The body length is always measured without the labrum; it is the distance from the anterior margin of the clypeus to the elytral apex (including the sutural spine). The width of the pronotum includes the lateral margins of the proepisterna (when the proepisterna and the notopleural sutures are visible from above). The width of the head is measured across the eyes, the distance between their outer margins. The term “aedeagus” here refers to the median lobe of the organ (without parameres). All dimensions of aedeagi are measured (and primarily figured) in their left lateral position when the basal portion (with basal orifice) points to the right and the left lateral outline (with dorsoapical orifice) faces dorsally, provided that the ventral (right) margin of the median portion is settled in its vertical position, and both upper and lower walls of the dorsoapical orifice are in the same line. The treatment and mounting of the aedeagi, in order to observe the structure of the internal sac, followed the usual procedure, modified and explained in MORAVEC (2002). The colour photographs (both of habitus and body portions, including aedeagi) were taken with a Coolpix 990 Nikon digital camera through an MBS-10 binocular stereo microscope. The keys below the illustrations feature these abbreviations of type status: HT = holotype; NT = neotype.

Brzoskaicheila gen.nov. (Coleoptera: Cicindelidae)

Ta x o n o m y Genus Brzoskaicheila gen.nov. Type species. Cicindela hispidula Bates, 1872: 264. Other species. Brzoskaicheila crassisculpta sp.nov.

Generic description. Body small, length 7.50–8.50 mm, width 2.00–2.70 mm, dark brown to black-brown with velvety black and feebly bronze or cupreous iridescent areas; setal vesture white to greyish. Head large with big eyes, as wide as the body or only very slightly narrower, surface finely or quite coarsely and irregularly rugose. Labrum yellow to ochre-testaceous, quite long in both sexes, with blunt or indistinct teeth in male, and with protruding, elongate median tooth in female. Thorax. Pronotum distinctly elongate but with ellipsoidal or subglobose disc, surface rather finely or coarsely rugulose; lateral thoracic portions and ventral sterna metallic, smooth and entirely glabrous, or nearly so. Elytra elongate, lateral margins subparallel or rather distinctly dilated in middle, coppery-brown to black-brown with conspicuous velvety-black area particularly on elytral disc, combined with cupreous or feebly golden-bronze iridescent areas; surface diversely, either rather finely or notably coarsely punctate on whole elytral length; white elytral maculation consisting of sublateral-median and anteapical maculae (humeral macula absent in both sexes). Legs. Coxae densely setose (metacoxae nearly glabrous, but lateral margin densely fringed with long white setae), trochanters glabrous with one apical seta, other leg segments quite densely setose. Abdomen. Ventrites either glabrous with only the usual sensory setae (in B. hispidula), or densely covered in minute setae (in B. crassisculpta sp.nov.). Aedeagus elongate, with distinctly dorsally hooked apex; internal sac simple, containing a short central spur crossed by a thin, arched spine supported by another short, thin, stiffening rib. Distribution. Occurring in southern Brazil in the states of Santa Catarina and Paraná (type species) and Madre de Dios, Peru (B. crassisculpta sp.nov.). Differential diagnosis. The new genus Brzoskaicheila gen.nov. is related to the genus Pentacomia Bates, 1872, with a small, similarly-shaped body and aedeagus and testaceous 4-setose labrum, but fundamentally differing in its remarkable setal vesture. In addition to the usual sparse sensory setae, the two species have their whole elytral surface densely covered with erect, rather long and mostly stiff setae; the pronotum and the head (partly) are also setose. Such setal vesture is a unique character within the genera Pentacomia and Odontocheila. In contrast to the setal vesture of the dorsal body surface, all the lateral thoracic portions and ventral sterna of the two species of Brzoskaicheila are entirely or nearly glabrous. This combination of characters separates the new genus clearly from all subgenera of Pentacomia. Aedeagus elongate, with distinctly dorsally hooked apex, internal sac simple. Superficially, due to the velvety black and iridescent areas on the elytra, the two species of the new genus may resemble the genus Ronhuberia Moravec et Kudrna, 2002. However, apart from the unique setal vesture in Brzoskaicheila gen.nov., the two genera may be distinguished by the coloration of the labrum, as well as by different patterns of internal sac in the aedeagi (MORAVEC & KUDRNA 2002).

Reasons for the neotype designation. The neotype is designated here because neither the holotype, nor any other specimen (not labelled as type) of this taxon has been found in the collections BMNH and MNHN, where type and other specimens by Bates should be deposited, either by myself or the relevant curators. No specimen of this taxon has been found in any other relevant collection, apart from the 11 specimens deposited in SDEI. Although the holotype of C. hispidula is very probably lost, according to the original description by BATES (1872) there is no doubt that the specimens examined from the SDEI collection, labelled “Brasil” or “Joinville” and “ Hansa, St. Catarina”, are conspecific with the holotype by BATES (1872). Their characters correspond perfectly with the original description, and also the locality of the here-designated neotype lies in the same southern area of Brazil. The locality of the lost female holotype was ambiguously mentioned in the protologue by BATES (1872) as “S. Brazil, Paraná, or Minas Geraes”, and further that the single female was collected by Mr. Rogers and donated by Edward Saunders. The type locality (of the neotype) lies in the state of Santa Catarina, situated near the state of Paraná which was mentioned in Bates’ protologue. Redescription. Body (Fig. 1) small, 7.30–8.50 (neotype 7.50) mm long, 2.20–2.70 (neotype 2.40) mm wide, dark bronze-cupreous, more vividly cupreous on head and pronotum, and predominantly iridescent bronze with weak greenish iridescence and velvety black areas on the elytra; frons, pronotum and elytra covered in erect or semierect, whitish to greyish setae, denser and stiffer on the elytra. Head (Fig. 3) with large eyes, in male slightly narrower than body, in female notably narrower, width 2.10–2.40 mm, generally concolorous with surface of other body portions. Frons quite steeply declining towards clypeus, moderately convex in middle, separated from vertex by frons-vertex fold, which is blunt in middle and edged laterally, surface nearly glabrous with only a few short, white setae in middle, cupreous, usually with greenish iridescence, median area covered in short, transverse, vermicular rugae, lateral areas longitudinally parallel striate-rugulose; supra-antennal plates large and flat, triangular, glabrous and almost smooth, metallic cupreous, usually with metallic green or bronze lustre of varying strength. Vertex concolorous with frons, nearly glabrous except for several short, hair-like setae, barely visible and easily abraded, and long, white juxtaorbital sensory setae (two on each side), with distinct anterior impression delimiting the frons-vertex fold, and two posterior sublateral impressions; median area densely but distinctly longitudinally parallel striate-rugulose to irregularly rugulose, subparallel to irregular rugae also cover juxtaorbital areas, while rugae on sublateral areas are parallel and longitudinal then wavy towards temples; occipital area irregularly wavy-rugulose. Genae glabrous, metallic cupreous with greenish and bronze reflections, shallowly, finely or more distinctly parallel striate-rugulose, postgenal area with a few wider, irregularly wavy rugae (running from lateral areas of vertex). Clypeus bright cupreous or dark copper, usually with green iridescence on lateral areas, finely and irregularly rugulose, glabrous.

Mandibles (Fig. 3) medium-sized, with arcuate lateral margins, ochre to brownishtestaceous (darker in female) with much paler inner basal area; teeth brownish or mahogany brown (darker in female), somewhat asymmetrical; each mandible in both sexes with four teeth (and basal molar), fourth tooth in left mandible smaller than the second and third which are almost of the same size, while the inner teeth of right mandible become progressively smaller towards the basal molar. Palpi (Fig. 3). Both maxillary and labial palpi almost unicoloured, ochre to brownish-testaceous (darker in female); penultimate (longest) palpomere of labial palpi in both sexes rather narrow, only moderately enlarged towards apex. Antennae rather short, reaching anterior elytral third, those of female even a little shorter, scape black-brown with strong, metallic green lustre, or mahogany-brown, with only one apical seta, antennomeres 2–5 ochre-testaceous with darkened apices and often with indistinct greenish lustre and only a few setae on antennomeres 3–4, antennomeres 6–11 becoming smoky-darkened, with indistinct micropubescence. Thorax. Pronotum (Fig. 6) elongate, 1.60–1.65 mm long, 1.20–1.30 mm wide, anterior lobe high and wider than posterior, sulci quite well-pronounced laterally but shallow dorsally; surface of anterior lobe nearly glabrous with only occasional, easily abraded setae; densely, but rather coarsely and irregularly rugulose, rugae on anterior area usually crumbled into short irregular rugae while posteromedian area adjacent to disc is usually parallel striate, striae converged in middle towards median line of disc; disc widely ellipsoid, usually with subparallel lateral margins in middle, or subglobose (usually wider in females), medial line distinct; discal surface densely and irregularly transversely striate-rugulose, striae converge in irregular fashion towards the median line; rugae on anterior and sublateral areas usually very irregular and irregularly directed, almost vermicular, but becoming transverse towards lateral margins; they do not exceed the notopleural sutures, or do so only slightly. The sutures are clearly differentiated and obvious in dorsal view; the whole discal surface quite densely covered with erect, rather long setae that are barely visible from above but obvious in lateral view, easily abraded; posterior lobe irregularly transverse-rugose, covered in a large number of setae laterally; prosternum, mesosternum and metasternum glabrous and nearly smooth, metallic black with greenish and bronze reflections; proepisterna, mesepisterna and metepisterna metallic black-copper with bronze and green reflections, glabrous and almost smooth, with only fine irregular wrinkles; female mesepisternal coupling sulci in the form of deep but wide longitudinal furrow.

Pro- and mesocoxae brown to black with metallic green lustre, quite densely setose, metacoxae metallic black-green with densely setose lateral areas; trochanters brownish-testaceous, glabrous except for one apical seta on pro- and mesotrochanters; femora almost black, but the coloration usually tending to chatoyant mahogany depending on angle of illumination, often with a greenish lustre, apices usually testaceous, but with metallic green lustre; profemora densely covered with rows of white, rather long setae which are sparser on mesofemora and far sparser on metafemora; tibiae brownish or almost testaceous except for black-darkened apical areas, and with more or less distinct greenish lustre, covered with scattered, thorn-like, whitish setae and brownish thorns; apical-ventral area of pro- and mesofemora with dense whitish to greyish setose pad; tarsi brownish-testaceous with metallic black apices; sometimes the metallic black coloration prevails; claws testaceous. Aedeagus (Figs 11–13) quite short, 1.95–2.00 mm long, 0.40–0.42 mm wide, basal portion distinctly bent, basomedian portion dilated, apical portion conically and progressively attenuated towards apex, which is ventrally rounded and dorsally hooked, beak-like; internal sac poorly developed, containing basally short central spur crossed by thin falciform spine and supported by another short, thin stiffening rib; other (upper) sclerites consist of a small, weakly-sclerotized arciform piece dorsally and a voluminous, but weakly sclerotized (and probably membranous) elongate sclerite of indefinite shape ventrally. Variability. Only unimportant variability in coloration. It should be noted that the erect setae on the head and pronotum are hardly visible in dorsal view, and that all the setae are very easily abraded. Acta Mus. Moraviae, Sci. biol. (Brno), 97(2), 2012

Differential diagnosis. Immediately distinguished from all species of the related genus Pentacomia Bates, 1872 by entire elytral surface densely echinate-setose. It differs from Brzoskaicheila crassisculpta sp.nov. especially in having dilated elytra with much finer and regular punctation, and black, polished and wide juxtaepipleural areas, unicoloured, ochre to brownish-testaceous palpi, much paler testaceous mandibles and antennomeres 2–3, slightly shorter labrum with protruding median lobe, less densely setose antennae and sparser setae on the frons, but longer setae on the vertex, and entirely glabrous proepisterna and surface of the ventrites. Biology and distribution. Known only from southern Brazil, the state of Santa Catarina (type locality), and probably from the neighbouring state of Paraná (type locality of the lost female holotype by BATES 1872) – see also “Remarks” below. ERWIN AND PEARSON (2008) mentioned diurnal activity for the adults, referring to ZIKAN (1929), but the latter author made no mention of this species. Remarks. The original description of Cicindela hispidula was based on a single female specimen (BATES (1872). Unfortunately, the holotype is not deposited either in BMNH and MNHN; further, the curators and I were unable to find it in any of the other collections including MNHUB. The species was only vaguely known: it was merely listed as Cicindela hispidula by FLEUTIAUX (1892), and was entirely unknown to RIVALIER (1969) who simply noted that he had ignored this taxon and its placement near Pentacomia. Some important characters of this species were mentioned by HORN (1902) when, somewhat ambiguously, he considered it as an “aberrant form of the genus Cicindela” and later (Horn 1915) as “aberrante Odontochilae”, while in HORN (1926) as “Cicindela gruppe Phyllodroma”. Apart from the author of the original description, Horn was thus the only entomologist to examine this species. It was illustrated in colour by HORN (1915: 400, plate 19, fig. 11) and later in an apt line drawing by HORN (1938: plate 83, fig. 9) clearly showing the densely setose elytra. SCHILDER (1953) quite inadequately transferred this species to the genus Phyllodroma Lacordaire, 1842, and as Phyllodroma hispidula it was also listed by WIESNER (1992), CASSOLA & PEARSON (2001), NAVIAUX (2002) and ERWIN & PEARSON (2008). The type species (by original designation) of the genus Phyllodroma is Phyllodroma cylindricollis, based on Cicindela cylindricollis Dejean, 1825, a species which differs widely from the two species of Brzoskaicheila gen.nov., as well as from all species of the related genus Pentacomia. RIVALIER (1969) introduced the genus Phyllodroma for the first time, characterized by the outstanding structure of its internal sac. The internal sac in Phyllodroma, in contrast to the genus Pentacomia, contains a long, multicoiled flagellum which is associated with a compact, translucent sustaining membrane, thus also differing from the long, spiraliform, but not so supported flagellum in the genus Odontocheila.

elytral surface densely covered in long, erect or semierect setae, finer and shorter on anterior area, becoming stiffer on posterior elytral half towards apices (Fig. 19); juxtaepipleural sensory setae scattered mostly in anterior area; elytral maculation whitish, consisting of only two maculae (humeral macula lacking): a sublateral-median macula which is slightly obliquely elongate, and anteapical elongate macula (running along the anteapical margin, but not reaching apex). Abdomen. Ventrites dark metallic black-copper, with the usual sparse, hair-like sensory setae on posterior margin of the ventrites, surface of last three ventrites (including terminal pleurites) densely covered in minute white setae. Legs. Pro- and mesocoxae brown-copper with paler apices and metallic-green lustre, quite densely setose, metacoxae metallic black-green with densely setose lateral areas; trochanters ochre-testaceous, glabrous except for single apical setae on pro- and mesotrochanters; femora much paler than in B. hispidula, pale brownish-testaceous with faint greenish iridescence, ochre on basoventral and subapical area, but apices blackdarkened; tibiae dark brown with apical half almost black; tarsi black; setal vesture of all leg segments as in B. hispidula, but setae denser; claws black with testaceous apices. Aedeagus (Fig. 20) similar to that of B. hispidula, but with more arcuate hooked apex; the internal sac was not examined in order to avoid damage to the single male holotype, which is tiny and fragile. Differential diagnosis. Immediately distinguished from Brzoskaicheila hispidula by much narrower and almost parallel-sided elytra with much coarser surface sculpture; metallic black-green penultimate and terminal palpomeres of maxillary palpi and terminal palpomeres of labial palpi; metallic green pedicel and darker metallic antennomeres 3–4; much more densely setose all antennomeres; proepisterna with scattered setigerous punctures, and densely, minutely setose surface of ventrites (in contrast to entirely smooth and glabrous proepisterna and surface of ventrites in B. hispidula). Moreover, the male labrum of the new species is almost semicircular with even more markedly effaced teeth, and the femora are notably paler. Biology and distribution. Known only from the type locality, the area of Madre de Dios in north-eastern Peru, a very long way from the south-eastern locality of B. hispidula. According to the collector, the only adult was caught flying on an eroded clay embankment more than 30 metres high, at the edge of the Alto Madre de Dios River.
