Paratypes, 3 ex. (2 ♂, 1 ♀), same data as holotype ( IRSNB, CPG) .

Diagnosi s. – A species of the P. babai -group sensu Schimmel, 1999, near P. weissi Schimmel, 2003 from Sumatra, for the general shape and colour, it can be separated for the longer antennae and the shiny surface of pronotum.

Description. – Male.

Shiny.

Coloration. – Entirely dark-ferruginous with vague dark shades around the base of pronotum and scutellum; covered with fine, recumbent, yellow-fulvous pubescence.

Head. – Frons convex on the vertex, flat on the middle, slightly impressed before the anterior margin, the latter arcuate, sub-horizontally projected above the clypeus, this with a mid-longitudinal carina; punctures coarse, simple or vaguelyumbilicate withshortest, shinyintervals. – Antennae long, exceeding by fourarticlesthe apices of theposterioranglesof pronotum,slightlyserratedfrom the fourtharticle on, longitudinally carinate from the thirdto theseventh,onlya vestige of dark mid-longitudinal line from the eight to the last articles; second article sub-cylindrical, third sub-conical, twice longer than the second, taken together a little shorter than the fourth; fourth-tenth sub-triangular, more than three times longer than wide,last sub-ellipsoidal.(Fig.25).

Pronotum. – 1.2x longer than wide, widest at the apices of the posterior angles, convex with a mid-longitudinal, narrow and shallow depression from the middle to the basal slope; sides nearly regularly tapering from the base to the apices, posterior angles long, acuminate, not divergent unicarinate; carina raised and directed inside, lateral margins complete and visible in a dorsal view in the first half; punctuation uniformly distributed, on the disk punctures deep, simple, with short, shiny intervals, a little denser towards the sides.

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

Elytra. – 2.7x longer thanpronotum and 3.x longer thanwide,moderately convex; sides from the base moderately and regularly tapering to the apices, the latter obliquely and slightly concave with a vestige of outer spine; striae well marked and punctured, interstriae flat and densely punctured.

Prosternal process. – Running sub-horizontal behind the procoxal cavities, cuneiform, not emarginate at apex.

Aedeagus. – As in the Fig. 4 (length 1.0 mm).

Female. – Very similar to the male, only with shorter antennae nearly reaching the apices of the posterior angles.

Size. – Length 9.2- 9.3 mm; width 1.87-1.93 mm.

Etymology. – The name is derived from Toegoé, the locality of Java where the species was collected.
