( Figs. 79 , 119 , 152 )

Material examined. Holotype ♀ - Pakistan: Islamabad , Sect. 7 (33°43'N, 73°03'E), 600 m, 1- 15.IX.2012, G. Sabatinelli leg., at light ( CPG). 5 Paratypes ♀♀ - same data as HT and 15.VI.2012 (3) ( CPG).

Diagnosis. A Drasterius Eschscholtz, 1829 allied to D. sulcatulus Candèze, 1859 separated for the pronotum just wider than long with very fine and short posterior angles and lighter punctuation.

Description.

Female. Moderately shiny; bicoloured; blackish with more or less expanded ferruginous colour to the posterior angles of pronotum and forming spots very variable in shape and extension on the elytra; antennae and legs yellowish; covered with dense, recumbent, yellow-fulvous pubescence.

Frons convex, anterior margin straight, just protruding above the clypeus, punctures of the same size, deep, simple, with very short intervals.

Antennae exceeding a little the middle of pronotum, slightly serrated from the fourth article on; second and third articles subcylindrical, the second is larger in diameter and a little longer than the third; second and third, taken together, 1.6x longer than the fourth; fourth to tenth subtriangular, the fourth longer than the following, fifth to tenth on average twice longer than wide, the last longer than the penultimate, ellipsoidal.

Pronotum 1.1x wider than long, widest behind the middle and at the apices of posterior angles, convex, abruptly sloping at sides and nearly vertically at base; sides subparallel and very feebly sinuate before the posterior angles, the latter acuminate, just divergent, with a short and well apparent carina directed forwards; lateral margins complete and visible only at basal part in a dorsal view; punctuation uniformly distributed; punctures approximately of the same size, deep, simple, with very short, shiny intervals.

Scutellum roundish, ridged at base, slightly convex, finely punctured.

Elytra 2.2x longer than the pronotum and as wide as it, convex; sides subparallel from the base to behind the middle then gradually tapering to the apices; striae well marked and punctured; interstriae subconvex with slightly rough surface.

Articles of tarsi regularly decreasing in length, simple.

Male unknown.

Size. Length 3.75-4.50 mm; width 1.12-1.46 mm.

Etymology. Dedicated to the collector, G. Sabatinelli.
