The identity of the poorly known xanthid crab Chlorodius miliaris A. Milne Edwards, 1873, from New Caledonia is clarified, and a new genus of Chlorodiinae is described for the species. Sulcodius n. gen. possess well-defined carapace regions; distinctly granulated cheliped surfaces; an anteroexternal angle of the basal antennal segment that extends into the orbital hiatus, filling it entirely; and a cheliped merus with a strongly grooved dorsal surface. The new genus is allied to Chlorodiella Rathbun, 1897, Pilodius Dana, 1851 and Phymodius A. Milne Edwards, 1863 and the relationships between the four genera are discussed, and distinguishing characters tabulated.
