Identification
Thevenetimyia can be distinguished from other bee fly by a combination of wing venation patterns and body proportions characteristic of the tribe Eclimini. Specific identification to species level requires examination of morphological details such as facial structure and abdominal patterning. The genus lacks the extremely long seen in some other bee fly genera.
