Etymology: Rivulus: Latin, rivus = stream (Ref. 45335); berovidesi: Named in honor to Professor Vicente Berovides Alvarez at the Faculty of Biology, Universidad de la Habana, Cuba in recognition of his life-long dedication and contribution to train several generations of new researchers in biological sciences (Ref. 101368).

Morphology | Morphometrics
soft rays: 8 - 11. Diagnosis: both males and females are readily distinguished from Rivulus cylindraceus by the presence of a dark lateral band situated longitudinally along the lateral line, extended from the posterior margin of the eye to the base of the caudal fin; dorsal fin slightly shifted to the caudal peduncle in relation to the origin of anal fin (1–3mm) when compared to Rivulus cylindraceus; frontal scalation pattern in Rivulus berovidesi sp. n. is d-type vs. e-type pattern in Rivulus cylindraceus (Ref. 101368).
Inhabits small mountain streams with bottom substrate basically composed by stones, sand and dead leaves; no aquatic vegetation in the area (Ref. 101368).

Phylogenetic diversity index (Ref. 82805
= 0.5010 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01023 (0.00415 - 0.02523), b=3.05 (2.83 - 3.27), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245
Trophic Level (Ref. 69278
): 3.1 ±0.4 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
