Blahnik, 1998, which also has spatulate lateral lobes of tergum X, but differs in having a distinctly bifid apex of its inferior appendage and much longer phallic spines. The species also seems to lack the array of short spines associated with the phallotremal sclerite complex seen in the new species, but these are easily overlooked in specimens in which the endotheca is not everted.

Abdominal segment IX, in lateral view, with well-developed anterodorsal apodemes, anteroventral margin distinctly extended, nearly linearly narrowing to dorsal apodemes, posterior margin weakly convex. Posteroventral process subtriangular, very large and prominent, length subequal to width at base. Tergum X membranous mesally, with sclerotized lateral lobes; lateral lobes, as viewed dorsally, spatulate in apical half, with two widely spaced sensilla near dorsal margin; as viewed laterally, turned down, with lateral crease in apical half. Preanal appendage short, rounded, knob-like, somewhat flattened as viewed dorsally. Inferior appendage, in lateral view, with rounded basal part and relatively narrow, moderately elongate; basal expansion weakly rounded to subtruncate, dorsal lobe with small tooth-like projection apicoventrally. Phallobase tubular, with basodorsal expansion, apicoventral margin only weakly projecting, two phallic spines, moderately elongate, subequal in length, endotheca apparently elongate, with small echinate spines. Phallotremal sclerite complex composed of rod and ring structure, rod short and curved and ring with prominent apicodorsal extension; apically with membranous structure subtending rod, anterior margin forming pair of weakly sclerotized, fishhook-like sclerites.
