Odocnemis hakkariensis

description: Odocnemis hakkariensis species-group
Description. Body not large (length up to 12 mm), dull. Temples without ventral groove. Hypomera with fine irregular wrinkles and large round punctures. Elytra without distinct tubercles. Epipleura flattened on elytral apex, their inner narrow carina reaching elytral sutural angle; epipleural dorsal carina not transformed into horizontal platform apically and connected with first convex elytral interval on apex. Wings absent. Abdominal ventrites. Male abdominal ventrites 1 and 2 without hair brush. Anal ventrite in both sexes without depression. Legs. Only male protibia with small teeth on inner side. Femora with punctation and pubescence on inner side, only apical median part smooth. Each trochanter with one long seta. Male genitalia. Apical piece not strongly thickened, without dorsal longitudinal depression, straight (lateral view). Basal piece 1.6 × as long as apical piece. Median lobe baculi not merged, acute on apex. Gastral spicula distinctly bent. Male inner sternite VIII weakly sclerotized, with dense punctation and setaetion, apices of the sternite widely rounded.
Distribution. South-eastern Turkey: Hakkari Mountains (Berçelan Yayla).
Composition. Only O. hakkariensis sp. n.

Type material. Holotype, ♂ (ZDEU) and 20 paratypes (4♂♂, 3♀♀ in ZIN; 1♂ in BMNH; 5♂♂, 4♀♀ (dry material), 3♂♂ (in ethanol) in ZDEU): Turkey, Hakkari Province, Berçelan Yayla, 3.vi.2013, 2700 m, 37°38′11.6″N 43°45′20.2″E, leg. M.V. and S.V. Nabozhenko, B. Keskin, A. Pektaş.
Description, male. Body length 6.4–10.2 mm, width 2.2–3.7 mm. Body slender, black, dull. Head widest at level of eyes. Eyes small, convex, widely located, strongly transverse (lateral view). Ratio of head width at eyes to distance between eyes: 1.4. Temples without groove in anterior part. Head covered with short recumbent hairs only near eyes and in base of clypeus. Anterior margin of clypeus bisinuate. Genae rounded in base and almost straight in anterior half. Lateral margin of head between genae and clypeus with weak emargination. Punctation of head moderately coarse and dense: punctures round, diameter of punctures subequal to distance between them. Antennae comparatively short (reaching 1/4–1/5 of elytral length), with 3 apical antennomeres extending beyond base of pronotum. Pronotum with subequal length and width (1.03–1.04 × as wide as long), weakly cordiform, widest in middle, 1.45 × as wide as head. Lateral margins weakly rounded, widely sinuate near base. Anterior margin straight or weakly rounded; base weakly rounded, bisinuate. Anterior angles acute, directed downwards (anterior view); posterior angles right, distinct on apex. Lateral margins narrowly regularly beaded, base with wider bead, anterior margin not beaded in middle. Disc moderately and regularly convex. Hypomera with very fine irregular wrinkles and large sparse round punctures. Elytra convex, elongate (1.7 × as long as wide), 1.2 × as wide and 2.25 × as long as pronotum, 1.8 × as wide as head. Strial punctures weakly elongate, sometimes connected in short furrows. Elytral intervals flat, with fine and sparse distinct punctation, without tubercles. Epipleural carinae not completely visible dorsally; epipleura reaching sutural angles of elytra. Narrow inner carinae of epipleura reaching elytral angles. Ventral side of body completely covered with short recumbent hairs. Punctation of metaventrite coarse and dense. Abdominal ventrites with denser and finer punctation. Ventrite 1 without hair brush; ventrite 5 without depression, beaded on apex. Legs short. Tibiae straight. Protibiae with 4–5 small teeth and line of granules; meso- and metatibiae without teeth and granules. Inner side of femora smooth in apical 1/4, punctated and pubescent with recumbent hairs on other surface. Each trochanter with one long seta.
Description, female. Body length 11–11.4 mm, width 1.4–1.5 mm. Body greater and more robust. Pronotum more transverse (1.15 × as wide as long). Elytra wider than in male (1.6 × as long as wide), 1.3 × as wide as pronotum. Antennae shorter (reaching only 1/8 of elytral length), with only 2 apical antennomeres extending beyond base of pronotum.
Etymology. The name comes from Hakkari Province.
Bionomics. The species was found in the alpine zone in very dry stony habitats under stones with foliose lichens.
Diagnosis. The new species differs from other Odocnemis by the absence of temple grooves, strongly elongated and transverse eyes and punctation of hypomera. Structure of epipleura the same as in O. inornata species-group.
