Scherocumella Watling, 1991b: 754.— Stoddart and Lowry, 2003: 373–418.
Type species. Nannastacus longirostris Sars, 1879.
Remarks. The carapace is as in the genus Nannastacus and the lenses grouped in two lateral pairs as always in Nannastacus. The pseudorostral lobes meet each other in front of the eyelobe, from base to top, similar to the genus Cumella and the uropodal peduncle is as long or even longer than pleonite 6, as in Cumella. Five species and one subspecies are known from Australia.
