Etymology

The species is named after the state from where it was collected.

Notes

This species is closer to P. siccarius in having the, mesosoma dorsally mostly black; F6 longer than wide and antenna dark brown, scape testaceous except, dorsoapically light brown, but differs in F1 1.36 × as long as pedicel; fore wing with an infuscate area around postmarginal and stigma vein; fore femur basal half brown, apical half yellow, tibia and tarsus yellow except apical tarsomere brown (F1 nearly 2.0 × as long as pedicel; fore wing with a single narrow subparallel transverse band from marginal to end of venation connecting anterior and posterior wing margins (fig. 8 of Annecke 1962); fore legs dark testaceous with faint blackish suffusions on the femora internally and tibiae externally in P. siccarius ).
