Short description Morphology | Morphometrics

Dorsal soft rays (total): 8-9; Anal soft rays: 12 - 13; Vertebrae: 30. Diagnosed from all other congeners of the subgenus Melanorivulus in possessing 2+1 mandibular neuromasts. Differs from all species of Melanorivulus, except Rivulus violaceus by its caudal peduncle in both sexes with dark purplish gray spots and humeral region in males with a bright greenish blue blotch. Can be separated from Rivulus violaceus by having fewer dorsal-fin rays 8-9 (vs. 10-11) and fewer anal-fin rays 11-13 (vs. 14-15). Additional characters helpful in the identification of this species include: scales in the longitudinal series 30-31; flank with close red dots, arranged in chevron-like series with the vertex on the mid-lateral line; and caudal fin in males with red bars (Ref. 76975).

Biology     Glossary (e.g. epibenthic)

Found mostly in a shallow swamp, about 10-20 cm deep, within a forest (Ref. 76975).

Estimates of some properties based on models

Phylogenetic diversity index (Ref. 82805):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00479 (0.00199 - 0.01154), b=3.14 (2.93 - 3.35), 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):  Low vulnerability (10 of 100) .
