Specific diagnostic features require examination under magnification and comparison with . The genus is morphologically similar to Pseudachorutes but differs in details of the and abdominal setation.
Distribution
Recorded from Europe, Caribbean mainland, East African Steppe, Himalayan region, and Malaysia. The wide but scattered distribution suggests either cryptic diversity or historical biogeographic connections across these regions.
