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.
Asia: restricted to the eastern slopes of the Knuckles Hills in the Kalu River at Pallegama, Sri Lanka at elevations of 300-500 m. Very rare and the only known existing population is in imminent danger of extinction due to the siltation of the Kalu caused by gem mining upstream. 亞洲: 在 Pallegama 的卡盧河中侷限於 Knuckles 的斜坡東部希爾了, 在海拔 300-500 公尺的斯里蘭卡。 非常稀有而已知唯一的現有族群是由於卡魯河上游開採珠寶礦石產生的淤泥的即將滅絕。

Adults of Puntius srilankensis are distinguished from P. filamentosus, P. singhala and P. assimilis by possessing a prominent black markings on body anterior to anal-fin origin. They differ from P. exclamatio by the absence of an elongate, tear-shaped black blotch above and anal fin; from P. arulius and P. tambraparniei by having mouth inferior and lower lip medially absent ( vs. mouth subterminal, lower lip entire) (Ref. 55036).
Body shape (shape guide): fusiform / normal. Puntius srilankensis 的成鱼被藉由在身体臀鳍前面起源上持有一个突出的黑色斑纹与 P. filamentosus ， P. singhala 与 区分 P. assimilis 。 他们不同于 P. exclamatio 藉由缺少一个延长 , 泪滴-形状的黑色斑块上方与臀鳍; 从 P. arulius 与 P. tambraparniei 借着具有嘴下方的与下唇中间地不存在( vs. 嘴接近端位的, 下唇整個的).(參考文獻 55036)
描述: 胸鰭有一單一的與 15個分支條。 在身體上側線有 21 或者 22個鱗片, 在尾鰭基底上有 1-2 個鱗片.(參考文獻 55036)
A mid-water fish found in areas of rapidly flowing water with pebbly substrate (not found in silty substrate). With a clearly defined territory (of several square meters) and without lateral spatial preferences. Individuals of the same size often form loose schools. Presently not available in sufficient numbers to be exported by the aquarium trade.
