sp. n. females have highly modified spermathecae (Figs 15-17). Although they have a transverse plate, it is very narrow and does not connect directly to the two receptacles (Figs 16, 17). The receptacles themselves are two long, slender tubes positioned parallel to the transverse plate and converging to the center. Despite the modified female genitalia, it is possible to include this species in the
