Comments: Known from middle rio São Francisco basin, between Irecê, Bahia and Santa Maria da Boa Vista, Pernambuco, NE Brazil (Ref. 49550). Considered cirically endangered due to small area of occupancy associated with the strong decline in quality of the habitat and abrupt reduction in subpopulations (Ref. 89836). Also Ref. 27139, 36579.

Short description Identification keys | Morphology | Morphometrics

Dorsal soft rays (total): 16 - 24; Anal soft rays: 19 - 24; Vertebrae: 28 - 30. Caudal peduncle of female with black spots. Male's anal fin with gray to black distal stripe, iridescent dots restricted to posterior portion of the fin, anterior part pink and posterior yellow; basihyal broad, 70-95% in length; and, second pharyngobranchial teeth, 5-10.

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=0.01995 (0.00906 - 0.04395), b=3.01 (2.83 - 3.19), in cm Total Length, based on all LWR estimates for this body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.3 ±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).

Price category (Ref. 80766): Unknown.
