Heteroderes curtus n. sp.

( Figs. 23, 23a , 82 , 116 , 155 )

Material examined. Holotype ♂ - Pakistan: Islamabad , Margalla Hills (33°46'N, 73°06'E), 1060 m, 22.VI.-20.VII.2011, G. Sabatinelli leg., at light ( CPG).

Diagnosis. A species allied to H. lenis Candèze, 1859 it can be separated by the shape of pronotum, very elongate with subparallel sides and elytra shorter (only 1.8x longer) compared to pronotum.

Description.

Male. Moderately shiny; entirely brownish with blackish shadings on head and pronotum; antennae and legs yellowish; covered with fine, dense, recumbent, yellow-golden pubescence.

Frons flat, anterior margin regularly arcuate and protruding above the clypeus; punctuation uniformly distributed with larger punctures more or less regularly mixed with very fine punctures.

Antennae not reaching the apices of the posterior angles of pronotum for about 1.5 articles, slightly serrated from the third article on; second article subcylindrical, short, as long as wide, third conical 2.6x longer than wide and 2.6x longer than the second; fourth to tenth subtriangular with the fourth a little longer than the following, on average more than twice longer than wide, the last one a little longer than penultimate, subellipsoidal.

Pronotum 1.37x longer than wide, widest at the apices of the posterior angles, very convex, abruptly sloping at sides and base; sides parallel for about all its length, posterior angles elongate, acuminate, not divergent, bicarinate; inner carina very short, outer carina longer and directed inside; lateral margins substraight, complete; punctuation uniformly distributed, double; larger punctures are regularly mixed with very fine punctures.

Scutellum quadrangular, ridged at base, slightly convex, very finely punctured.

Elytra 1.8x longer than the pronotum and as wide as it, convex, ovaliform, striae well marked and deeply punctured, interstriae subconvex, very finely punctured.

Fourth article of tarsi with a wide lamella partially visible in a dorsal view.

Aedeagus as in Figs. 23, 23a (length 1.34 mm).

Size. Length 10.60 mm; width 2.62 mm.

Etymology. The name is derived from the very short elytra compared to the pronotal length.
