Identification
Acrotaeniini can be distinguished from other Tephritinae tribes by combinations of patterns, (bristle arrangement), and male genitalic structures. within the tribe often share reduced and modified surstyli. Specific identification to genus level requires examination of wing pattern details, chaetotaxy, and in males, the structure of the and associated genitalic components. The genus Tomoplagia is notably diverse and may require dissection for definitive identification.

Distribution
The tribe is primarily distributed in the New World, with occurring in the Nearctic and Neotropical regions. Individual genera show varying distributions: Tomoplagia is widespread in the Americas, while other genera such as Acrotaenia and Baryplegma have more restricted ranges. The exact distribution boundaries for the tribe as a whole remain incompletely documented.
