Males of P. tolgaensis were identified from fig. 35 of Watts (2010b). They have an unusually wide T8: the plate is about twice as wide as the distance between its straight apodemes. The penis is flat, and the upcurved tip of trigonium bears fine denticles. The endophallus is armed with several very slender and long teeth.
