Short description Identification keys | Morphology | Morphometrics

Dorsal soft rays (total): 4; Anal soft rays: 57 - 73; Vertebrae: 53 - 58. Unusually large genital papilla; males with a long conical papilla, while females with a flat, leaf-shaped papilla with a small projection at the tip. A unique combination of the following characters: head width 11.6-15.4% SL, head depth 8.2-9.9% SL, pelvic fin length 7.5-9.6% SL, length of dorsal fin base 0.8-1.9% SL, depth of caudal peduncle 6.2-7.6% SL, and principal caudal fin rays 14-16 (Ref. 41525). Dark brown body; dorsal surface purple; stomach light gray; all fins are light gray (Ref. 40516). Eye circular (Ref. 43281).

Adults inhabit streams. They feed actively at night on small fish, crustaceans and insects.

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=0.00589 (0.00350 - 0.00989), b=3.00 (2.85 - 3.15), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).

Trophic level (Ref. 69278): 3.8 ±0.59 se; based on food items.

Resilience (Ref. 120179): Medium, minimum population doubling time 1.4 - 4.4 years (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Low to moderate vulnerability (30 of 100).

Price category (Ref. 80766): Unknown.
