Identification
Aleodorus can be distinguished from other Falagriini by a combination of characters including the structure of the and details of the mouthparts, though precise identification requires examination of genitalic characters. The genus is placed in Falagriini based on tribal synapomorphies including the presence of a distinct mesosternal process and specific configurations of the tarsal segments. Species-level identification within Aleodorus relies on subtle differences in male genitalia and patterns of the abdominal sternites.
Distribution
Distributed in the Americas. Documented occur in North America, with records from the United States. The full extent of the 's range in Central and South America is suggested by estimates of 15–18 total species but requires further documentation.
