Traces to section 27 (females) in Cushman's revision of the genus (Proc. U. S. N. M. Vol. 53, p. 513, 1917). Differs from mordellistenae Cush. in having the wings brownish and the face sub-equal in width to the eye length. Differs from incompletus (Prov.) in the brownish wings, the absence of pale orbital lines, broader stigma, broader radial cell and shorter metacarpus. Resembles fuscipennis Cress., but smaller with narrower face, eyes parallel within and abdomen wholly blackish. The male traces to section 13 (males) differing from the male of mordellistenae in the brownish wings, the absence of orbital rings and uniformly dark abdomen. From incompletus it differs in the brownish wings, broader ocellocular space which is slightly greater than the diameter of the lateral ocellus, and the lack of the orbital rings.
