Short description Identification keys | Morphology | Morphometrics

Dorsal spines (total): 0; Dorsal soft rays (total): 13; Anal spines: 0; Anal soft rays: 8. Row of comparatively large tubercles present on enlarged, elongate scales rows immediately above and below the lateral line scale row on the anterior half of the caudal peduncle; color pattern of 11-15 dorsal saddles, a series of 8- 13 lateral blotches centered along the lateral line, and without a dark spot at anterior base of dorsal fin (Ref. 42961).

Recorded from shallow, clear streams with gravel or sand bottom (Ref. 42961). Juveniles also known from murky water (Ref. 42961).

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=0.00724 (0.00347 - 0.01512), b=3.01 (2.83 - 3.19), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 2.8 ±0.3 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).
