deskripsi pendek
Morfologi | Morfometrik
duri punggung lunak (Keseluruhan (total)): 8-9; Sirip dubur lunak: 13 - 14; vertebrata, bertulang belakang: 31. Belongs to the subgenus Owiyeye and differs from other congeners, except Rivulus altivelis, Rivulus nicoi, Rivulus tecminae and Rivulus uakti, by possessing long pelvic fins (pelvic-fin length up to about 25 % of SL, reaching the middle of
anal-fin base in males vs. short pelvic fin, reaching anterior portion of anal-fi n base). Can be separated from other species of the subgenus (except for Rivulus amanapira,
Rivulus rectocaudatus and Rivulus tecminae) by truncate caudal fin in males (vs. round, subtruncate, spatula- or lyre-shaped caudal fin). Its 35-38 scales in the longitudinal series separate this species from other species (vs. 41-44 in Rivulus altivelis, 48-49 in Rivulus amanapira and 38-43 in Rivulus rectocaudatus and Rivulus tecminae, 26-29 in Rivulus nicoi and 32-33 in Rivulus uakti) (Ref. 87326).
Found in a pond with clear, light brownish color and very acidic water (Ref. 87326).

Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 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): 3.2 ±0.4 se; based on size and trophs of closest relatives
Fishing Vulnerability (Ref.
59153): Low vulnerability (10 of 100).
