Figs. 31, 39, 45, 463, 502, 529, 547, map 4.

Holotype (female): Indonesia: Taliaboe [1°48'S, 124°48'E], Ins. Archipel, IV.1909, M. v. Nouhuys, depository: Nationaal Natuurhistorisch Museum ("Naturalis"), Leiden, Netherlands ( RMNH).

Diagnosis. P. taliabu differs from all other species of the genus by the characteristic shape of the female subgenital plate that is excised for about half of its length ( Fig. 463); the apex of lobes is truncate ( Fig. 529); on each lobe there is a white collar extended dorso-laterally into a rounded flap ( Fig. 502); behind that collar with a pyriform structure with little depressed surface ( Fig. 463).

Description. Fastigium verticis ( Fig. 39) in front of eyes 0.9 mm, from base 1.4 mm; dorsal eye length 1.7 mm; greatest diameter of eye 1.8 mm; index fastigium verticis from base: eye length 0.8. Face rugose ( Fig. 31). Prosternal spines much shorter than fore coxa. Femora with the following number of spines on ventral margins: fore femur 6 external, 7–8 internal; mid femur 5–6 external, 2 internal near base; hind femur 9–12 external, 4–7 internal.

Male unknown.

Female. Eight abdominal tergite with lateral areas little shortened. Tenth abdominal tergite furrowed in midline. Subgenital plate in basal half with a deep median furrow strongly widening laterad at very base; with a high median carina in this furrow; apical half divided; resulting lobes each covered for the greatest part by an elevated socket that is subdivided by secondary furrows and carinae: anterior area white, forming an elevated collar open behind, posterior area forming a large curved groove; apical part of lobes proper little elevated, flat, with apex truncate, deeply excised between lobes; lateral margin of lobes swollen and sinuate; baso-lateral areas strongly curved dorsad, forming an ovoid lobe with secondary furrows and carinae ( Figs. 463, 502, 529). Ovipositor sickle-shaped.

Coloration. Uniformly yellowish brown (discoloured due to former conservation in alcohol). Face reddish brown, mandibles black except at very base. Pronotum with a vertical brown spot on paranota along hind margin ( Fig. 45). Tegmen with brown cells and yellow veins.

Measurements of female body 27; pronotum 8.3; tegmen 27; hind femur 19; antenna 110; ovipositor 15.5 mm.

Etymology. Named after the type locality; noun in apposition.
