Abstract
Devario anomalus, new species, is described from a small coastal stream south of Cox’s Bazar, Chittagong Division, Bangladesh. The new species can be distinguished from all other species of Devario by its unique colour pattern. It is further distinguished from all congeners reported from Bangladesh by a combination of characters, including its shorter P-stripe, the presence of maxillary barbels, an ascending process on the first infraorbital, and a lower number of lateralline scales, branched dorsal-fin rays, branched anal-fin rays, and circumpeduncular scale rows.
