Based on paratype female, 3.0 mm, AM P37408 (Myers, 1988b). Sternal spines absent. <i>Gnathopod 1</i> carpus less than two thirds length of propodus; palm with distal shallow excavation, defined by robust seta; dactylus overlapping palm. <b>Habitat.</b> Rubble, algal turf, <i>Ecklonia radiata</i> holdfasts, <i>Sargassum</i> sp., <i>Jania</i>. <b>Remarks.</b> The dorsal pigmentation of this species is unique in the genus. <b>Distribution.</b> <i>Australia</i>.
