Xanthopenthes sabatinellii n. sp.

( Figs. 29, 29a , 123 , 159 )

Material examined. Holotype ♂ - Pakistan: Islamabad , Margalla Hills (33°46'N, 73°06'E), 1060 m, 16.VII.2012, G. Sabatinelli leg., at light ( CPG).

Diagnosis. The westernmost species of the genus containing a high number of species from India to the Oriental Region, it could be compared with X. modestus (Candèze, 1859) but it is immediately separated for the slenderer body, darker colour, and subtrapezoidal pronotum.

Description.

Male. Moderately shiny; entirely blackish with ferruginous shadings at base of pronotum; antennae and legs yellow-ferruginous; covered with dense, semierect, fulvous pubescence.

Frons convex on vertex, flat at the anterior margin, this complete, arcuate and just protruding above the clypeus; punctures coarse, umbilicate with very short intervals or contiguous.

Antennae exceeding by about two articles the apices of posterior angles of pronotum, moderately serrated from the third article on; the third to tenth article with a mid-longitudinal carina; second article subcylindrical, very short, globous, third article subconical, twice longer than wide and 2.8x longer than the second; fourth to tenth triangular, fourth a litle longer than the following and twice longer than wide; fifth to tenth on average twice longer than wide, the last one as long as the penultimate, ellipsoidal.

Pronotum as long as wide, widest at the apices of the posterior angles, very convex; abruptly sloping at sides, nearly vertically at base; sides nearly regularly and gradually narrowing from the base to the apex; posterior angles acuminate, just divergent at the extremities, bicarinate; carinae short, subequal in length and directed inside; lateral margins complete and visible in a dorsal view in the basal third; punctuation uniformly distributed; punctures superficial, umbilicate with very short, shagreened intervals.

Scutellum shield-shaped, with subparallel sides in the first half then narrowing to the apex, flat, densely punctured.

Elytra 2.55x longer than the pronotum and as wide as it, convex; sides subparallel in the first half then very gradually tapering to the apices; striae well marked and punctured, gradually more superficial towards the apices; interstriae flat with rough surface.

Aedeagus as in Figs. 29, 29a (length 1.62 mm).

Female unknown.

Size. Length 9.35 mm; width 2.37 mm.

Etymology. Dedicated to the collector, G. Sabatinelli.
