Diagnosi s. – A species of the P. asper -group sensu Schimmel, 1999, comparable to P. parallelus Schimmel, 2003 for the general shape and size, it can be separated for the shinier body, bicoloured elytra, longer pronotum with posterior angles longer and most divergent, sub-parallel elytra.

Description. – Male.

Shiny.

Coloration. – Head, antennae, pronotum, scutellum, underbody and legs ferruginous, elytra lighter, yellowish, vaguely darkened along the suture and laterally after the sixth intervals; covered with dense, partially erect on elytra and sides of body, yellow pubescence.

Head. – Impressed in the middle, anterior margin in the middle very fine, always distinct, directed downwards to nearly touching the clypeus; punctures strongly umbilicate, contiguous. – Antennae reaching the apices of posterior angles of pronotum, serrated from the fourth article on; second and third articles, small, globous, subequal in length, taken together as long as the fourth; fourth-tenth triangular gradually slenderer, fourth-sixth less than twice longer than wide, seventh-tenth more twice longer than wide, the last a little longer, ellipsoidal. (Fig. 34).

Pronotum. – 1.09-1.14x longer than wide, widest at the apices of the posterior angles, convex, with a short mid-longitudinal impression on the basal slope; sides regularly and moderately arcuate, sinuate before the posterior angles, the latter long, acuminate, divergent, unicarinate; carina sharp, short and directed inside.

Scutellum . – Shield-shaped, ridged at base, slightly convex, densely punctured.

Elytra. – 2.55x longer than pronotum and 2.7x longer than wide, convex; sides perfectly parallel from the base to behind the middle then gradually tapering to the apices, the latter rounded and entire; striae well punctured, interstriae densely punctured, with wrinkled, shiny surface.

Aedeagus. – As in the Fig. 13 (length 1.37 mm).

Size. – Length 7.5-8.7 mm, width 1.75-2.06 mm.

Female. – Unknown.
