Tamanho / Peso / Idade
Maturidade: Lm ?  range ? - ? cm
Max length : 19.5 cm TL macho/indeterminado; (Ref. 57129)
Espinhos dorsais (total) : 0; Raios dorsais (total) : 64 - 70; Raios anais : 51 - 55; Vértebras: 53 - 56. Diagnosis: length of vomerine tooth plate not exceeding length of premaxillary tooth plate; barbels not exceeding head length (Ref. 57129). Head rather pointed in dorsal outline; snout rounded; eyes dorsal; frontal fontanelle short and squat ('sole-shaped'); occipital fontanelle small and oval-shaped; supraorbital and `dermosphenotic' bones fused; tooth plates small; dorsal and anal fins not confluent with caudal fin; suprabranchial organ well developed; openings of secondary canals of lateral line appear as irregularly placed white spots on body (Ref. 248).
Body shape (shape guide): elongated; Cross section: oval.
Facultative air-breathing (Ref. 126274); The species' biology is unknown (Ref. 78218).
