Short description Identification keys | Morphology | Morphometrics

Dorsal soft rays (total): 12; Anal soft rays: 8. Distinguished by a broad black midlateral stripe and another stripe along the back in specimens smaller than about 4 cm SL; larger specimens with vertical bars connecting the two stripes and extending to the lower half of the body; fins hyaline in small specimens and marked in larger ones (Ref. 27732).

Occurs in riffles, in clear, fast-flowing water (Ref. 27732). Found in small creek with sandy bottom and moderate current (Ref. 37841) and hill streams (Ref. 58784). Feeds on insect larvae and benthic organisms (Ref. 58784).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.7500 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00589 (0.00248 - 0.01401), b=3.10 (2.90 - 3.30), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.2 ±0.4 se; based on size and trophs of closest relatives

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