Triepeolus rohweri Cockerell, 1911
Diagnostic description:
The pseudopygidial area of this species is similar to that of T. margaretae; however, the two species differ in that only T. rohweri has erect, simple setae on the mesepisternum. The pseudopygidial area is also similar to that of T. claytoni, but these are distinguishable by the angle formed by the lateral longitudinal and apical transverse bands of pale setae on T2 (forming an acute angle in T. claytoni, forming a 90 degree angle in T. rohweri)
