Species account taken from "Diadasia Patton; A Genus of Bees Author(s): T. D. A. Cockerell Source: The American Naturalist, Vol. 39, No. 466 (Oct., 1905), pp. 741-745"

Male:Length 7.5 mm. ; like D. dimituta Cr., but with shorter, perfectly white pubescence, and a narrower, more parallel-sided abdomen; the pubescence of the abdomen, instead of being loose and suberect as in male diminuta, is appressed (except on first segment) and covers the surface aside from the pubescence, the hind margins of the segments are themselves white; the apex is bidentate, the teeth being like those of diminuta, but rather larger; hind legs constructed as in diminuta shining hairless triangle of metathorax much smaller than in dimizla ; posterior part of mesothorax almost nude tegulae subhyaline, ferruginous, dark at base; antenna entirely black.
