Remarks
This species is part of a group with a specific kind of subanal appendages (number 28 in Fig. 8), which includes P. queirozi andP. fallaciosus sp. n. The species has an intermediary number of subsegments on Ant. IV (nine subsegments), has no eyes, lacks the corner tooth in all unguiculi, and the inner lamella of the mucro is smooth. This combination of features can easily differentiate the three species.
Despite its wide distribution, P. hermesi sp. n.presents some features that may be indicative of its relation to the SSH environment, for instance eye reduction, Ant. IV shorter (nine subsegments), overall small body size, and the reduction of the corner tooth and apical filament on unguiculus.
