A new leucosiid crab genus, Nobiliella n. gen., is proposed for Nursia jousseaumei Nobili, 1905 (type species) and N. jousseaumei var. cornigera Nobili, 1905, the latter of which should be raised to the specific rank as Nobiliella cornigera n. comb. Nobiliella n. gen. is readily distinguished from Nursia Leach, 1817 by the form of the carapace, the reduced mouth parts and the formula of the male abdomen. Nobiliella n. gen. is similar to Philyra Leach, 1817 in the form of the carapace, the mouth parts and the male abdomen, but is distinguished by the dorsal ridges of the carapace, the triangular tooth of the metabranchial margin and the medially concealed first segment of the female abdomen.
