Short description Claves de identificación | Morfología | Morfometría

Espinas dorsales (total) : 0; Radios blandos dorsales (total) : 12 - 14; Espinas anales: 0; Radios blandos anales: 9 - 11. Diagnosis: distinguished from Neolebias by its always complete lateral line; caudal peduncle 1-1.5x longer that high (Ref. 2936, 86396). 32-36 scales in a longitudinal series (Ref. 81638, 86396). Four, rarely 5, scales between dorsal fin origin and lateral line (Ref. 81638). 11-16 (Ref. 86396) or 12-14 (Ref. 81638) total dorsal fin rays. 10 (Ref. 86396) or 9-11 (Ref. 81638) total anal fin rays.

Distinguished from Neolebias by its always complete lateral line (Ref. 2936). Feeds on worms, crustaceans and insects (Ref. 7020).
