Abstract - Smith and Radcliffe described Neamia octospina in 1912. The genus was considered monotypic until a second species was discovered recently in the marine waters of Mauritius, Indian Ocean. Neamia notula sp. nov., differs from N. octospina in having 14 instead of 17-21 pectoral rays; eighth dorsal spine hidden by skin instead of visible, larger eyes, more slender body depth and an opercular spot instead of none. Neamia octospina, a widespread species, is reviewed. There is consistent variation in pectoral-fin ray counts between the Indian Ocean and West Pacific. There is no other morphological evidence to support recognition of more than one Widespread species at this time.
