背面の脊椎 (合計) : 0; 背鰭 (合計) : 6 - 9; 肛門の骨: 0; 臀鰭: 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).
Body shape (shape guide): fusiform / normal.
Inhabits small mountain streams with bottom substrate basically composed by stones, sand and dead leaves; no aquatic vegetation in the area (Ref. 101368).
