Abstract
Taxonomic analysis of three specimens of Macrognathus collected from Manimala River reveals that they present several morphological differences from their congeners. The new species is diagnosed by a combination of the following characters: body dirty white without any bands or bars, eyes are closely set, spinous part of dorsal fin originating considerably behind the end of pectoral fin; pre orbital spine absent, 29 irregular blotches present on mid dorsal line from top of operculum to base of caudal. The new species is described and compared with its relatives.
