Etymology

Dawkinsia is named after the evolutionary biologist Richard Dawkins in recognition of his "contribution to the public understanding of science, particularly, of evolutionary science".[1]^: p.80 Dawkins describes this as "a great honour".[2]

Description

Adults typically measure 8–12 cm (3.1–4.7 in) SL. They do not have rostral barbels but might have maxillary barbels. Juveniles have a colour pattern consisting of three black bars on body; this persists to adult stage in some species. Adults have a black, horizontally elongate blotch on the caudal peduncle .Found in western ghats.[1]^: p.80
