Diagnosis.

Body length: female 14 mm. A large species with elongate, not constricted abdomen. The tergites are reddish with a median blackish vitta on tergites 3 and 4. The wings are yellow anterobasally and blackish along the margins. The fascia of golden pile along the transverse suture of the mesonotum is widely interrupted medially. The face is darkened medially. This species is morphologically very similar to P. bidens , from which it differs by the partly yellow wings and the dark median vitta on tergites 3 and 4. It differs from P. angustiventris and P. luridescens by the widely interrupted fascia of golden pile along the mesonotal transverse suture.

Notes.

The type of this taxon is considered lost, and Reemer (2014) designated a neotype.

Distribution.

Known from French Guiana and Suriname.
