Short description Identification keys | Morphology | Morphometrics

Dorsal spines (total): 1; Dorsal soft rays (total): 6; Anal spines: 0; Vertebrae: 31. Diagnosis: labial disk longer than broad, very large and rounded; mandibular barbels very small (Ref. 57223, 81251). No auxiliary mandibular barbels; premaxillary teeth large in 7-8 rows (Ref. 81251). Mandibular teeth usually in 2 rows, numbering 8+8 to 10+10 (in smallest specimens 6+6 to 7+7); adipose fin small/short, beginning slightly ahead of anal-fin origin; caudal peduncle slender, elongate; caudal fin (moderately) forked, lobes more or less equal in size; eyes very small; sexual dimorphism does not seem to exist, although mature individuals have never been examined (Ref. 57223, 81251). Coloration: live specimens: uniformly dark, nearly black, except on abdomen/belly which is light; alternation of dark and pale areas typical of Chiloglanis species has not been observed in fresh specimens of this species, but becomes slightly apparent after preservation (Ref. 57223, 81251).

Oviparous (Ref. 205).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01000 (0.00244 - 0.04107), b=3.04 (2.81 - 3.27), in cm total length, based on all LWR estimates for this body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.1 ±0.4 se; based on size and trophs of closest relatives

Resilience (Ref. 120179): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Low vulnerability (10 of 100).
