DISTRIBUTION. Sunda Islands: Borneo, Java, Bali. The below given description of P. yanbulat sp.n. poses a question: if Crosskey’s New Guinean record from Kassam (6.24°S 146.00°E) was a misidentification of P. yanbulat sp.n. or both species are distributed in New Guinea? Colleagues from Bishop Museum may examine Kassam’s specimen and clarify the situation.

REMARKS. Males from Malaysian Borneo in ZMUM collection seem to be the first known males of nominotypical subspecies of P. u. unicolor . Male genitalia are identical to those of P. u. crosskeyi ssp.n. ( Figs 8 and 10 ), differences between two subspecies are in body size and leg colour of males.

Among 11 ♂♂ of P. u. unicolor there is one with remarkable femoral chaetotaxy: setae on f2 and left f3 are reduced while right f3 has 3 pv and 2 av setae almost as strong as in females.
