Abstract
    Echinolatus n. gen. is described for four species, E. bullatum (Balss, 1923), from the Juan Fernandez Islands off Chile, E. caledonicum (Moosa, 1996) from New Caledonia, E. proximum n. sp. from French Polynesia, and E. poorei n. sp. from the Great Australian Bight and southern Victoria. The first two species had been previously attributed to Nectocarcinus A. Milne Edwards, 1860. Echinolatus is characterised by a subhexagonal carapace, a quadrilobate front, at least the last pair of anterolateral carapace teeth, and usually others, bearing spinules or spiniform denticles on the anterior margins, the chelipeds having the carpus armed with a long pointed tooth at its anterointernal angle which also has a smaller strong tooth basally. E. bullatum is redescribed.
