The allotype female and four additional paratypes, all males, bear the same locality, date, and collector data as the holotype. In the original description, Malloch stated that a paratype would be deposited in the British Museum (Natural History).

but is distinguished from it by the mostly yellow mid- and hindfemora, which have at most the apical one-fourth to one-third dark, and the shape of the surstylus (Fig. 35) short and widely truncate apically. The surstylus of

is long, J-shaped. From other congeners, this species is distinguished by the following characters of males: the pale-colored basal flagellomere and apex of the ventral projection of the pedicel, the whitish microtomentum on the mid-dorsal surface of the face, the relatively approximate antennal bases, and the narrowly triangular areas that extend medioventrally from the ventral margin of the antennal groove. The shape of structures of the male terminalia also clearly distinguishes this species (see Figs 35-38).
