These include the occurrence of a fifth oostegite in the females, the presence of coupling hooks on the pleopod protopods and simple robust setae distoventrally on the uropodal protopod (see above). Importantly, the diagnosis is inaccurate with regard to the character he regarded as having particular diagnostic importance.

, some of which are discussed above. Foremost among these are the minute and vestigial terminal segment of the antennula, the shape and form of the telson (including the apex and posterolateral margins), and the degree of fusion of the coxae of pereonites 2 to 4. These are largely free; fusion has not extensively limited mobility, sutures are still clearly visible and coxae and epimera are exposed. The utility of these characters will become more apparent following a more comprehensive revision of the species included in the genus and the description of more taxa.
