Short description Morphology | Morphometrics

Dorsal soft rays (total): 10-11; Anal soft rays: 16 - 17. Can be diagnosed from all congeners, except Rivulus igneus, by the presence of a dark greenish blue blotch on the upper portion of the opercle, and lower jaw, distal portion of anal fin and lower portion of caudal fin orange in males. Differs from Rivulus igneus by having fewer scales in the longitudinal and transverse series and by the presence of a black round spot on the upper portion of the caudal-fin base in females (Ref. 86530).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00661 (0.00311 - 0.01404), b=3.09 (2.91 - 3.27), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.3 ±0.4 se; based on size and trophs of closest relatives

Fishing Vulnerability (Ref. 59153): Low vulnerability (10 of 100).
