Vertebrae: 36. Rasbora wilpita is distinguished from all congeners from peninsular India and Sri Lana by the combination of the following characters: a prominent symphysial knob on lower jaw; a -conspicuous maxillary lateral process; head depth 54-62% HL; and body depth 24.7-29.3% SL (Ref. 84057).
Inhabits shallow, slow-flowing, heavily shaded streams (Ref. 6028).

Estimates based on models
Phylogenetic diversity index (Ref. 82804
= 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00832 (0.00354 - 0.01952), b=3.09 (2.90 - 3.28), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245
Trophic level (Ref. 69278
): 3.2 ±0.4 se; based on size and trophs of closest relatives
Resilience (Ref. 120179
): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153
): Low vulnerability (10 of 100).
