French Guiana • 1 ♀; Roura, Kaw Road, PK37 (km 37), Relais Patawa; 04°32'42"N, 52°09'09"W; Nov. 2008; J.A. Cerda leg.; RMNH.

Diagnosis.

Body length: male 13.5 mm, female 12.5 mm. The constricted abdomen, absence of a triangle of golden pile on the mesoscutum, and partly dark wings place this species in a group with P. diaphanus , P. elongatus , and P. hermetia . From P. diaphanus it differs by tergite 2 being approx. as wide as long, from P. elongatus by the absence of yellow in the vena spuria, from P. hermetia by the entirely infuscated wing cell bm. The male genitalia are figured in Fig. 262 .

Distribution.

Known from Guyana and French Guiana.
