Holotype, ♂, Indonesia, W Java, Soekaboemi, ex. coll. Le Moult ( IRSNB).

Diagnosi s. – A small species of the P. dorsalis -group sensu Schimmel, 1999, comparable to P. subinfumatus n. sp. from Sumatra, separated for the shorter antennae, a vestige of a second inner carina on the posterior angles of pronotum, shorter elytra compared to pronotum.

Description. – Male.

Moderately shiny.

Coloration. – Great part of head, pronotum, scutellum, the first two and the last lateral striae of elytra dark brown; anterior margin of head, anterior pars of pronotum with the posterior angles, the remaining pars of elytra, yellowish; covered with dense, yellow-fulvous pubescence.

Head. – Frons convex, flat immediately before of the anterior margin, the latter perfectly arcuate, directed downwards, projected above the clypeus; punctures strong, umbilicate, contiguous. – Antennae nearly reaching the apices of posterior angles of pronotum, serrated from the fourth article on, second article sub-cylindrical, third sub-conical, subequal in length, taken together, as long as the fourth; fourth-tenth triangular, on average 2.2x longer than wide, last sub-ellipsoidal. (Fig. 31).

Pronotum. – Long as wide, widest at the apices of the posterior angles, convex, with a vestige of mid-longitudinal depression on the basal slope; sides from behind the middle regularly tapering to the apices, sub-parallel to the posterior angles, the latter long, very acuminate, very slightly divergent, bicarinate; outer carina fine, longer slightly diverging from the lateral margins, inner carina shorter, just visible and sub-parallel to the first; lateral margins complete, in the first half visible in a dorsal view; punctuation coarse, punctures umbilicate with shortest intervals or contiguous on all the surface, except before the posterior angles where is very fine.

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

Elytra. – 2.5x longer than pronotum and 2.5x longer than wide, convex; sides nearly regularly tapering from the base to the apices, the latter truncate; striae deeply punctured, interstriae sub-convex, very finely punctured.

Aedeagus. – As in the Fig. 11 (length 0.66 mm).

Size. – Length 5.41 mm, width 1.5 mm.

Female. – Unknown.

Etymology. – The name is derived from Java, the island where the species was collected.
