Etymology: Devario: Bangla/Bengali:‘debari’, local name for these fishes; also meaning ‘brother in law’ (Ref. 2031); gibber: From the Latin gibber (gibbous, humpbacked). More on author: Kottelat.

Morphology | Morphometrics
soft rays: 12 - 14. Complete lateral line; 2 pairs of barbels, rostral barbel slightly shorter than the eye diameter, maxillary barbel much shorter; infraorbital process rudimentary or absent; caudal peduncle 1.3-1.6 times longer than deep; head relatively slender in lateral view, with a small hump on nape; cleithral spot present; 3 or 4 dark bluish stripes on side (Ref. 36949). In specimens larger than about 3 cm SL, stripes irregular anteriorly, sometimes zigzag shaped or dissociated into series of spots, spots of different series can be connected (Ref. 43281).

Estimates based on models
Phylogenetic diversity index (Ref. 82805
= 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00891 (0.00371 - 0.02139), b=3.05 (2.85 - 3.25), 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.).
Vulnerability (Ref. 59153
): Low vulnerability (15 of 100) .
