Short description Morphology | Morphometrics

Adults differ from Puntius filamentosus, P. singhala and P. assimilis by possessing prominent black markings on body anterior to anal-fin origin. Distinguished from P. exclamatio by lacking an elongate, tear-shaped black blotch above anal fin. Differs from P. srilankensis by having mouth subterminal and lower lip entire (vs. mouth inferior and lower lip medially absent). Distinguished from P. tambraparniei by lacking branched dorsal-fin rays elongated into filaments in adult males (vs. present) and by having a pair of maxillary barbels <0.5% SL (vs. 2.4-4.7%) (Ref. 55036).

Estimates of some properties based on empirical models

Phylogenetic diversity index (Ref. 82805): PD₅₀ = 0.5020 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00932 (-0.15492 - 0.17355), b=3.03035 (2.94265 - 3.11805), based on LWR estimates for this family-BS (Ref. 93245).

Trophic Level (Ref. 69278): 2.8 ±0.3 se; Based on size and trophs of closest relatives

Resilience (Ref. 69278): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).

Vulnerability (Ref. 59153): Low vulnerability (23 of 100) .

Price category (Ref. 80766): Unknown.
