Identification
Triploechus can be distinguished from other Bombyliidae by wing venation patterns, particularly the arrangement of in the portion of the wing. The name refers to the triple swelling (Greek: triplo- echus) of certain wing veins, a diagnostic character. Edwards (1937) noted narrow-winged forms in T. angustipennis, while Hall (1975) described luridus and stagei based on coloration and structural differences. Exact separation from related genera such as Bombylius requires examination of vein R4+5 branching and the presence of specific spurs on the hind tibia.

Taxonomic History
Authorship dates vary in sources: Edwards 1936 (Catalogue of Life) versus 1937 (GBIF). The discrepancy likely reflects publication versus description dates. Hall (1975) significantly revised the , adding two new (T. luridus, T. stagei) and clarifying relationships among previously described .
