Remarks. Anthidiellum coronum and the closely related A. latipes belong to a distinctive group within the subgenus that in Asia also includes A. rasorium (Smith) , A. ramakrishnae (Cockerell) , and A. butarsis Griswold. They are distinguished from other Asian Pycnanthidium by the omaular carina reaching the ventral midline, the absence of longitudinal carinae on the outer faces of the hind legs, and the enlarged hind basitarsus of the female ( Griswold, 2001).
