The specific epithet "tibialis" suggests that the tibia (third leg segment) bears a distinguishing characteristic useful for identification, possibly coloration, spination, or structural modification. As a member of Dasypogoninae, it likely exhibits the traits of a mystax (beard of bristles on the ) and forelegs adapted for prey capture. Positive identification requires comparison with , particularly examination of leg characters and male terminalia.

Distribution

Behavior

As with other Asilidae, are aerial that perch on vegetation or bare ground to ambush flying insect prey. They are hunters with excellent vision.

Ecological Role

robber flies function as that help regulate of other insects. They occupy intermediate trophic positions in terrestrial .
