背棘 (总数) : 0; 背的软条 (总数) : 6 - 9; 臀棘: 0; 臀鳍软条: 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).
