This new species has a 2-segmented exopod on leg 4 and the distal exopodal segment carries 4 spines. It shares this form of leg 4 with about 90 congeneric species, although only 15 of them have similar body proportions in the adult female, with a genital complex (without posterolateral lobes) that is about as long as wide and about twice as long as the abdomen, which is itself about as long as wide. The species possessing this form of leg 4 and most closely matching these body proportions are:
