Etymology: Dawkinsia:Named for Richard Dawkins, for his contribution to the public understanding of science and, in particular, of evolutionary science. Eponymy: Dr Clinton Richard Dawkins (d: 1941) is an ethologist and evolutionary biologist who was Professor for Public Understanding of Science (1995–2008) at Oxford, which had awarded both his bachelor’s degree (1962) and his doctorate (1966) and where he [...] (Ref. 128868), visit book page.

Adults measuring >4.33 cm SL differ from all other South Asian Puntius by a combination of the following characters: a black band about as wide as eye across each caudal-fin lobe (faint or absent in adults of the Kallada River population); 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. Adult males from the Chalakudy and Kallada River populations with branched dorsal rays prolonged into filament-like extensions. Adults of P. assimilis may be distinguished from P. filamentosus by possessing mouth inferior (vs. subterminal) and maxillary barbels 23.5-33.3% HL (vs. 2.8-8.1%) (Ref. 55036).
Body shape (shape guide): fusiform / normal. 成魚測量 >4.33 公分 SL 藉著下列特徵的一個組合不同於所有其他南亞 Puntius: 一條黑色的條紋橫過大約等寬於眼每個尾鰭葉;(模糊的或者不存在於 Kallada 河的成魚族群) 下唇連續 , 在 2-5個鱗片上的一個尾部的斑塊, 開始在臀鰭起源後面; 沒有在身體上的明顯的斑紋在臀鰭起源前面。 雄性成魚從 Chalakudy 與 Kallada 河川族群用分枝的背鰭鰭條延長到像絲狀突起一樣的延長內了。 P. assimilis 的成魚可能是藉由持有嘴下方的 (vs. 接近端位的) 與顎的觸鬚 23.5-33.3% HL(vs.2.8-8.1%) 與 P. filamentosus 區分。 (參考文獻 55036)
描述: 胸鰭有一單一的與 14個分支條。 側線有 19 或 20個鱗片, 在尾鰭基底上的 2個有細孔的鱗片.(參考文獻 55036)
Occurs in a variety of habitats such slow-flowing areas close to the banks with muddy substrate, clear-water, rock substrate areas and relatively fast-flowing waters (Ref. 55036).
