Etymology
Its generic name, Dawkinsia, is named after renowned British evolutionary biologist Richard Dawkins, for "his contribution to the public understanding of science and, in particular, of evolutionary science".
Diagnosis
Adults differ from all other South Asian Puntius by a combination of the following characters:
branched dorsal-fin rays prolonged into filament-like extensions in adult males only; a black band about as wide as the eye near tip of each caudal-fin lobe; lower lip continuous; a caudal blotch on 2-5 scales, commencing posterior to anal-fin origin; no distinct markings on body in advance of anal-fin origin. Distinguished from P. assimilis by Possessing a subterminal mouth (vs. Inferior); maxillary barbels shorter, 0.5-2.2 of SL % (vs. 5.5-9.3%); post-orbital head length 11.0-12.1% of SL (vs. 8.7-10.4%); and interorbital width 11.2-12.2% of SL (vs. 10.0-11.1%) . Description: Pectoral fin with one simple and 14 or 15 branched rays. Lateral line with 18,19 or 20 scales on body, extending 1-3 scales on to caudal-fin base.
Distribution
Endemic to but widespread within the Western Ghats mountains region of southern India in the states of Kerala, Tamil Nadu and possibly restricted to the south of the Karnataka.
Type locality is 'Alleppey', also known as Alappuzha, situated between Vembanad Lake and the Arabian Sea, Kerala state, southwestern India
Habitat
According to Pethiyagoda and Kottelat (2005) this species is most common in lowland coastal floodplains. It is found in both fresh and brackish waters of rivers, estuaries, coastal marshes and reservoirs.
Fishing
Along the rivers of Kerala, these fishes grow in abundance and due to its high diet of worms and insects, they are easily caught with baits by fishermen especially during the monsoon season when they are more widely found.
