However, for this study I focused on the structure of male cerci, both because cerci are easy to handle and to isolate from the rest of the specimen and because the usefulness of cercal characters has already been well established by Orchelimum systematists (Rehn and Hebard 1915; Blatchley 1920; Thomas and Alexander 1962; Walker 1971).

The genus can be characterized by presenting occipital procces; four-segmented palpi; wings with 1-3 mm long, R5 joining C beyond the wing apex, Rs weaker than R1, but evident; variable tarsal claws (toothed or simple, and curved near basal third or beyond), empodia usually reaching to the curve of the claws or sometimes shorter; quadrate or secondarily lobed or acute male cerci; aedeagus usually elongate and tapering to the apex or sometimes large and bulbous; ovipositor short, barely protrusible; and female cerci separate.
