簡短描述
型態特徵 | 形態測量圖
背的軟條 (總數): 6-8; 臀鰭軟條: 12 - 13; 脊椎骨: 31 - 32. This species is distinguished from other species in the Rivulus santensis group in having scales in longitudinal series 30-31 (vs. 32-36); caudal fin light yellow, with a dark gray broad margin along the whole fin (except R. nudiventris, vs. absent in R. depressus, R. lazzarotoi, R. simplicis; margin restricted to dorsal and ventral margins of the caudal fin in R. janeiroensis, R, santensis, and R. haraldsiolii; and black margin, middle with bright green and dark reddish brown to black longitudinal lines in R. luelingi); dorsal part of caudal fin base in females with a small, horizontally elongated black spot (vs. rounded or triangular). This species differs from R. nudiventris by having a pelvic fin (vs. none), lesser caudal-fin rays 25-29 (vs. 30-31) and anal-fin rays 12-13 (vs. 14) (Ref. 78703).
The type locality near the lagoon, to Lagoa do Pires, is part of a series of lagoons close to the sea, isolated from river basins. It is an open area of Restinga vegetation, the swamp dense with aquatic vegetation, clear and acidic (pH 5.28) water (Ref. 78703).
