Material studied: 1♂, 1♀: LA RÉUNION, 12.II.2018, above La Plaine des Cafres , sifting in forest, 1580 m, - 21.241227S; 55.585655E, Hlaváč P. & Kocian M. lgt., (cKoc) .

Remarks. This is an endemic species to Réunion, with strongly reduced wings. It is very similar to P. janaki sp. n. and differs from late only in male terminalia. In contrast to P. janaki sp. n., male sternite VII ( Fig. 12 ) is with less numerous short dark modified setae along the posterior margin. Male sternite VIII ( Fig. 18 ) is similar to that of P. janaki sp. n. The ventral process of aedeagus ( Figs 9–11 ) is broader in its basal part, as wide as the dorsal plate, and the apex is distinctly asymmetrical. The ventral process of the aedeagus in its basal portion is more protuberant in lateral view. The ear-like lateral processes of the dorsal plate of the aedeagus clearly extend beyond the overall lateral profile of the aedeagus when viewed ventrally or dorsally.

The material determined as P. gomyi and published by Janák (2014) is in fact P. janaki sp. n.

Distribution: Réunion.
