Short description Identification keys | Morphology | Morphometrics

Dorsal spines (total): 7; Dorsal soft rays (total): 9 - 10; Anal spines: 1; Anal soft rays: 8 - 9. Distinguished from all other members of the genus by the following combination of characters: 8-9 anal rays; dorsal fins with VI - I,9-10 rays; first dorsal fin with a diagonal black band; females with a thin dark band crossing the chin; juvenile females with a triangular dark patch in region of isthmus; orange pigmentation on dorsal surface of body, and caudal and pectoral fin bases in both juveniles and adults; light blue or turquoise mottling on the head, nape and dorsal surface; sexually dimorphic head morphology (% HL), head lengths similar, males with 5% greater eye diameter and 30% greater lower jaw length, females with 5% greater snout length, 7% greater post orbital length and 6 % greater head width; sexually dimorphic fin morphology (% SL), males with 5% larger first dorsal fin base and females with 7% larger pectoral and 5 % larger pelvic fins (Ref. 55545).

Seems to prefer shallow and clear water riffles with slow or moderate current speed and with a substrate of small boulders and gravel (Ref. 55545).

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=0.00977 (0.00442 - 0.02163), b=3.05 (2.86 - 3.24), 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

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).
