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.

Korte beschrijving Determinatiesleutels | Morfologie | Morfometrie

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).

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).

Estimates based on models

Fylogenetische diversiteitsindex (Ref. 82804):  PD50 = 0.5020   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01072 (0.00502 - 0.02287), b=3.02 (2.84 - 3.20), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trofisch niveau (Ref. 69278):  2.6   ±0.1 se; based on size and trophs of closest relatives
Weerstandsvermogen (Ref. 120179):  Hoog, minimale populatieverdubbelingstijd minder dan 15 maanden (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (10 of 100).
