Resembles ellopiae Hgtn. in structure and sculpture, but with abdomen entirely black, not red as in that species. In Cushman's and Townes's synopses it traces to sodalis Ruthe, which it resembles in color, but from which it differs in its rounded, rather strongly receding temples, shorter malar space, narrower ocellocular space, very narrow epipleura of abdominal segments two, three, and four, the absence of median longitudinal propodeal carinae, and the much paler color of the wings.
