Delineation of this species among the large collection before us proved difficult, with only a very few specimens conforming closely to the holotype. In describing the species,

fig. 56 (redrawn here from the type in Fig. 14), except that the subgenital processes are gently curved mesally, not slightly sinuous as figured by Kelley. A considerable number of specimens have been examined that agree in general features, but have abdominal segment IX either shorter but much the same shape as in the holotype male, or more elongate and rounded anteriorly; in some the spine on the phallic apparatus is longer and more strongly recurved and arising closer to the apex than in the type. This latter form is illustrated in Fig. 17 and was initially thought to be a separate species. However, following examination of further material of forms intermediate between

together with all newly available specimens with the apico-ventral margin of abdominal segment IX truncate, sometimes with some slight marginal sclerotisation, the gonopods reduced to short domes, and abdominal segment IX sub-triangular to conical. Future studies may show reveal that these represent more than one species.
