Glyphonyx occidentalis sp. n.

( Figs 15 , 75)

Material examined. Holotype, male: Afghanistan: “NO.Afghan.1952 J.Klapperich Kamdesch 2000 m, 16.VII. Nuristan Bashgultal” ( HNHM).

Diagnosis. The species is immediately recognizable by the generic features and is the first species of the genus west of North India. It can be compared with G. bicolor Candèze, 1893 from Japan for the general shape, length of antennae, elytral colour lighter than head and pronotum but can be distinguished for the short carina of posterior angles of pronotum and male genitalia.

Description. Male ( Fig. 15 ). Head and pronotum blackish, elytra lighter, dark brown, antennae and legs yellow-ferruginous; covered with dense, recumbent, yellowish pubescence.

Frons convex, clypeal margins v-shaped; puncturation coarse, slightly umbilicate, with very narrow shiny intervals.

Antennae reaching posterior angles of pronotum, serrated from fourth antennomere on, second and third antennomeres subcylindrical with second a little longer, taken together, 1.5× longer than fourth; fourth to tenth subtriangular, on average less than twice longer than wide, last longer than penultimate, ellipsoidal.

Pronotum 1.1× wider than long, widest at posterior angles, strongly convex, abruptly sloping on sides and base; sides subparallel in middle, gradually converging in anterior third, slightly sinuate before posterior angles, latter truncate and subparalllel at apical extremity, shortly carinate and parallel to lateral margins, this complete; puncturation uniformly distributed, punctures of disk deep, moderately umblicate, with very short, shiny intervals.

Scutellum shield-shaped, a little longer than wide, ridged at base, flat, finely punctured.

Elytra 2.6× longer than pronotum and as wide as it, convex, sides almost regularly and gradually converging from base to apices, striae well marked, distinctly punctured; interstriae flat, with wrinkled and punctured surface.

Fourth tarsomeres lobed and longer than wide. Claws pectinate.

Aedeagus as in Fig. 75 (length 0.85 mm).

Female unknown.

Size. Length 4.87 mm; width 1.4 mm.

Etymology. The specific epithet refers to the fact that this is the westernmost species of Glyphonyx in the Palaearctic region.
