Author: Robertson, 1891.

Identification
Both sexes can be distinguished from those of barbilabris by the more distinct pronotal humeral angles and dorsoventral ridges and by the very weak terga fasciae. The female of erythronii is marked by a labral process distinctly broader than long, the clypeus is strongly flattened and more or less shiny, propodeal dorsal enclosure is weakly sculptured. The male of erythronii is marked by the sterna having weakly formed subapical fimbriae and tergum 7 without or with an extremely narrow pygidium-like area.
Remarks
Spring bee of eastern North America, associated with trout lilies (Erythronium spp.).
