P. latusmandibularis   is an isolated species with many unique characters ( Watts 2010b) and stands by itself. It is derived in possessing prominent projections of the frontoclypeus but shares none of the apomorphies characteristic of the following species ( Table 2).

Female. Recognized by the enlarged mandibles. Sternites 3−6 connate and forming deep stiff trough to which S7 is hinged. Antecosta of S7 with two paramedian knobs resembling short apodemes. S6 with central oblique porus with strongly sclerotized dark walls. Ovipositor normal, coxites and stylites slender. Apodemes of S8 slightly sinuous, lyre-shaped, at front end approaching but not visibly connected. Short section of gonoduct annulate ('concertinated') and internally covered with what seem to be dense microtrichia or hair-like spinules. Bursal sclerite not observed, the bursella itself hyaline, surface with several large areas of smooth cuticle with microridges along edges.
