A new hoplichthyid species, Hoplichthys mcgroutheri, is described on the basis of six specimens (188-244 mm standard length) collected off southwestern Australia. It is clearly distinguished from its congeners by the following combination of characters: dorsal-fin rays V-14; anal-fin rays 16-17, usually 16; pectoral-fin rays 13-14 + 4-5 = 17-18, usually 14 + 4 = 18; infraorbitals mostly spineless; scales present on dorsal surface of body; vomerine tooth patch constricted medially, mostly separating teeth into bilaterally symmetrical patches; interorbit narrow [interorbital width 5.8-6.8 % of head length (HL)]; and orbit relatively large (orbital diameter 41.8-44.9 % HL). The form of the vomerine tooth patch is unique to H. mcgroutheri in this genus.
