Dicronychus islamabadensis n. sp. ( Figs. 22, 22a , 27, 38, 57)

Material examined. Holotype ♀ - Pakistan: Islamabad , 15.VIII.2011 ( CPG).

Diagnosis. A species immediately separated from all the known species of the region because of the last abdominal sternite shortly emarginated before the apex.

Description.

Female. Moderately shiny; entirely dark ferruginous with undefined blackish shadings; antennae and legs yellow-ferruginous; covered with dense yellow -golden pubescence.

Frons flat, only just impressed before the anterior margin, this moderately arcuate and just protruding above the clypeus; punctuation dense, coarse; punctures deep, simple or vaguely umbilicate with very short intervals or contiguous.

Antennae mutilated (only five articles of the left antenna are present), not reaching the apices of posterior angles for about two articles (estimated); second article subcylindrical, twice longer than wide, fourth-fifth conical, 2,7x longer than wide and subequal in length.

Pronotum 1,1x wider than long, widest at the middle, convex; sides arcuate, from the middle nearly regularly converging to the posterior angles, the latter truncate, not divergent, with a very short, few visible carina; lateral suture-like margin curved and interrupted after the middle; punctuation dense, uniformly distributed, punctures fine, simple, approximately of the same size with intervals smooth and smaller than their diameters, on the basal slope the punctures are extremely fine.

Scutellum heart-shaped, as long as wide, impressed at middle, emarginate at middle of the base, finely punctured.

Elytra 2,6x longer than pronotum and as wide as it, very convex, ovaliform with sides widest at the middle, striae well marked and punctured, interstriae subconvex finely punctured.

Claws dilated in the first half.

Last abdominal sternite emarginate before the apex as in the Fig. 27.

Bursa copulatrix sclerified as in the Figs. 22, 22a .
