Etymology: Devario: Bangla/Bengali:‘debari’, local name for these fishes; also meaning ‘brother in law’ (Ref. 2031); udenii: Named for Udeni Edirisinghe, Professor of Animal Science of the University of Peradeniya, Sri Lanka, for his enormous contributions to ichthyology of Sri Lanka; and for continuing support of biodiversity research and education in Sri Lanka..

Morphology | Morphometrics
soft rays: 15 - 18;
Vertebrae: 35 - 36. Devario udenii differs from all its congeners by the combination of following characters: body depth 26-36 %SL; snout length less than eye diameter; color pattern comprising of 5-6 dark, irregular, broad, vertical bars anterior to level of dorsal-fin origin; 14-17 predorsal scales; dorsal fin with 9½-12½ branched rays and anal fin with 12½-15½ branched rays; presence of danionin notch; dorsal fin origin to hypural distance, when carried forward, reaching middle of eye; pectoral fin, when adpressed, reaching origin of pelvic fin; and P-1 stripe subequal in width to P stripe (Ref. 118056).
Inhabits fast-flowing water within moderately shaded areas (Ref. 118056).

= 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00977 (0.00422 - 0.02262), b=3.04 (2.84 - 3.24), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245
Trophic level (Ref. 69278
): 3.0 ±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).
