IntroductionThis paper is part of a series (MORAVEC 2012) that aims to make important

taxonomic and nomenclatorial results available before the completion of a finalcomprehensive publication, currently in preparation, which will provide a thoroughrevision of the Neotropical genera of the subtribe Odontochilina W. Horn, 1899 in a newsense. The new genus Brzoskaicheila gen.nov. is related to the genus Pentacomia Bates,1872, but is clearly distinguished from all four currently-known subgenera ofPentacomia by a complex of characters, including the unique setation of the dorsal bodysurface, particularly elytra densely echinate-setose throughout their length. Theinfrageneric subdivision and the generic delimitation of the Neotropical generaPentacomia Bates, 1872, Odontocheila Laporte de Castelnau, 1834, Cenothyla, Rivalier,1969, Phyllodroma Lacordaire, 1843 and others, proposed by RIVALIER (1971), has beencommonly 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 generamentioned above, RIVALIER (1969, 1971) characterized the subtribe Prothymina in termsof the tetra-setose labrum in combination with entirely glabrous thoracic and abdominalsterna. However, this ignores the fact that many Pentacomia species and several speciesof Odontocheila possess setal vesture, developed to a greater or lesser extent, in the form

of setose lateral thoracic portions, ventral thoracic sterna, ventrites, or even dorsal bodysurface; some of them also exhibit sparsely setose pronotum and densely clustered setaeon 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 ofthe subtribe Prothymina W. Horn, 1910 sensu RIVALIER (1969, 1971). Therefore, asindicated by MORAVEC (2012), the subtribe Odontochilina should be restored and newlydefined for only the Neotropical genera. Naturally, a final classification remains to beproposed in the concluding publication after comprehensive revision.

Material and methodsThe 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 widthof the pronotum includes the lateral margins of the proepisterna (when the proepisternaand the notopleural sutures are visible from above). The width of the head is measuredacross the eyes, the distance between their outer margins. The term “aedeagus” hererefers to the median lobe of the organ (without parameres). All dimensions of aedeagi aremeasured (and primarily figured) in their left lateral position when the basal portion (withbasal orifice) points to the right and the left lateral outline (with dorsoapical orifice) facesdorsally, provided that the ventral (right) margin of the median portion is settled in itsvertical position, and both upper and lower walls of the dorsoapical orifice are in thesame line. The treatment and mounting of the aedeagi, in order to observe the structureof 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 stereomicroscope.

Brzoskaicheila gen.nov. (Coleoptera: Cicindelidae)

Ta x o n o m yGenus 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, darkbrown 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, surfacefinely or quite coarsely and irregularly rugose.

Labrum yellow to ochre-testaceous, quite long in both sexes, with blunt or indistinctteeth 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 sternametallic, 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 onelytral disc, combined with cupreous or feebly golden-bronze iridescent areas; surfacediversely, either rather finely or notably coarsely punctate on whole elytral length; whiteelytral maculation consisting of sublateral-median and anteapical maculae (humeralmacula absent in both sexes).

Legs. Coxae densely setose (metacoxae nearly glabrous, but lateral margin denselyfringed with long white setae), trochanters glabrous with one apical seta, other legsegments quite densely setose. Abdomen. Ventrites either glabrous with only the usualsensory setae (in B. hispidula), or densely covered in minute setae (in B. crassisculptasp.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 genusPentacomia Bates, 1872, with a small, similarly-shaped body and aedeagus andtestaceous 4-setose labrum, but fundamentally differing in its remarkable setalvesture. In addition to the usual sparse sensory setae, the two species have their wholeelytral surface densely covered with erect, rather long and mostly stiff setae; thepronotum and the head (partly) are also setose. Such setal vesture is a unique characterwithin the genera Pentacomia and Odontocheila. In contrast to the setal vesture of thedorsal body surface, all the lateral thoracic portions and ventral sterna of the twospecies of Brzoskaicheila are entirely or nearly glabrous. This combination ofcharacters 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 twospecies of the new genus may resemble the genus Ronhuberia Moravec et Kudrna,2002. However, apart from the unique setal vesture in Brzoskaicheila gen.nov., thetwo genera may be distinguished by the coloration of the labrum, as well as bydifferent patterns of internal sac in the aedeagi (MORAVEC & KUDRNA 2002).

Reasons for the neotype designation. The neotype is designated here because neitherthe holotype, nor any other specimen (not labelled as type) of this taxon has been foundin the collections BMNH and MNHN, where type and other specimens by Bates shouldbe deposited, either by myself or the relevant curators. No specimen of this taxon hasbeen found in any other relevant collection, apart from the 11 specimens deposited inSDEI. Although the holotype of C. hispidula is very probably lost, according to theoriginal description by BATES (1872) there is no doubt that the specimens examined fromthe SDEI collection, labelled “Brasil” or “Joinville” and “ Hansa, St. Catarina”, areconspecific with the holotype by BATES (1872). Their characters correspond perfectlywith the original description, and also the locality of the here-designated neotype lies inthe same southern area of Brazil. The locality of the lost female holotype wasambiguously mentioned in the protologue by BATES (1872) as “S. Brazil, Paraná, orMinas Geraes”, and further that the single female was collected by Mr. Rogers anddonated by Edward Saunders. The type locality (of the neotype) lies in the state of SantaCatarina, 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 andpronotum, and predominantly iridescent bronze with weak greenish iridescence andvelvety black areas on the elytra; frons, pronotum and elytra covered in erect orsemierect, whitish to greyish setae, denser and stiffer on the elytra.

Head (Fig. 3) with large eyes, in male slightly narrower than body, in female notablynarrower, width 2.10–2.40 mm, generally concolorous with surface of other bodyportions.

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, usuallywith 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 orbronze lustre of varying strength.

Vertex concolorous with frons, nearly glabrous except for several short, hair-likesetae, barely visible and easily abraded, and long, white juxtaorbital sensory setae (twoon each side), with distinct anterior impression delimiting the frons-vertex fold, and twoposterior sublateral impressions; median area densely but distinctly longitudinallyparallel striate-rugulose to irregularly rugulose, subparallel to irregular rugae also coverjuxtaorbital areas, while rugae on sublateral areas are parallel and longitudinal then wavytowards 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).

Differential diagnosis. Immediately distinguished from all species of the related genusPentacomia Bates, 1872 by entire elytral surface densely echinate-setose.

It differs from Brzoskaicheila crassisculpta sp.nov. especially in having dilatedelytra with much finer and regular punctation, and black, polished and widejuxtaepipleural areas, unicoloured, ochre to brownish-testaceous palpi, much palertestaceous mandibles and antennomeres 2–3, slightly shorter labrum with protrudingmedian lobe, less densely setose antennae and sparser setae on the frons, but longer setaeon 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 thelost 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 latterauthor made no mention of this species.Remarks. The original description of Cicindela hispidula was based on a single femalespecimen (BATES (1872). Unfortunately, the holotype is not deposited either in BMNHand MNHN; further, the curators and I were unable to find it in any of the othercollections including MNHUB. The species was only vaguely known: it was merelylisted as Cicindela hispidula by FLEUTIAUX (1892), and was entirely unknown toRIVALIER (1969) who simply noted that he had ignored this taxon and its placement nearPentacomia. Some important characters of this species were mentioned by HORN (1902)when, somewhat ambiguously, he considered it as an “aberrant form of the genusCicindela” and later (Horn 1915) as “aberrante Odontochilae”, while in HORN (1926) as“Cicindela gruppe Phyllodroma”. Apart from the author of the original description, Hornwas thus the only entomologist to examine this species. It was illustrated in colour byHORN (1915: 400, plate 19, fig. 11) and later in an apt line drawing by HORN (1938: plate83, fig. 9) clearly showing the densely setose elytra.

SCHILDER (1953) quite inadequately transferred this species to the genusPhyllodroma Lacordaire, 1842, and as Phyllodroma hispidula it was also listed byWIESNER (1992), CASSOLA & PEARSON (2001), NAVIAUX (2002) and ERWIN & PEARSON(2008). The type species (by original designation) of the genus Phyllodroma isPhyllodroma cylindricollis, based on Cicindela cylindricollis Dejean, 1825, a specieswhich differs widely from the two species of Brzoskaicheila gen.nov., as well as from allspecies of the related genus Pentacomia. RIVALIER (1969) introduced the genusPhyllodroma for the first time, characterized by the outstanding structure of its internalsac. The internal sac in Phyllodroma, in contrast to the genus Pentacomia, contains along, multicoiled flagellum which is associated with a compact, translucent sustainingmembrane, thus also differing from the long, spiraliform, but not so supported flagellumin the genus Odontocheila.

elytral surface densely covered in long, erect or semierect setae, finer and shorter onanterior 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 maculawhich is slightly obliquely elongate, and anteapical elongate macula (running along theanteapical margin, but not reaching apex).

Abdomen. Ventrites dark metallic black-copper, with the usual sparse, hair-likesensory 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- andmesotrochanters; femora much paler than in B. hispidula, pale brownish-testaceous withfaint greenish iridescence, ochre on basoventral and subapical area, but apices black-darkened; tibiae dark brown with apical half almost black; tarsi black; setal vesture of allleg 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 hookedapex; the internal sac was not examined in order to avoid damage to the single maleholotype, which is tiny and fragile.Differential diagnosis. Immediately distinguished from Brzoskaicheila hispidula bymuch narrower and almost parallel-sided elytra with much coarser surface sculpture;metallic black-green penultimate and terminal palpomeres of maxillary palpi andterminal palpomeres of labial palpi; metallic green pedicel and darker metallicantennomeres 3–4; much more densely setose all antennomeres; proepisterna withscattered setigerous punctures, and densely, minutely setose surface of ventrites (incontrast to entirely smooth and glabrous proepisterna and surface of ventrites in B.hispidula). Moreover, the male labrum of the new species is almost semicircular witheven more markedly effaced teeth, and the femora are notably paler. Biology and distribution. Known only from the type locality, the area of Madre de Diosin 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 clayembankment more than 30 metres high, at the edge of the Alto Madre de Dios River.
