Diagnostic characteristics

(modified from Michener and Griswold 1994)

May be confused with

Acedanthidium may resemble Eoanthidium and Pseudoanthidium due to similar body form and size (Michener and Griswold 1994). Acedanthidium resembles Eoanthidium due to the presence of foveate scutoscutellar suture. However, Acedanthidium can be differentiated from those genera by its lack of a juxtantennal carina and the simple female S6 (Michener 2007). Acedanthidium can be differentiated from Pseudoanthidium based on the characteristics listed above.
