Issue
The most recent distributional records were published by Weitzman & Weitzman (1982: Fig. 229). Most recent systematic description by Weitzman (1966). Locality records including the locality of the original collections are discussed by Weitzman & Cobb (1975). Lectotype designated by Weitzman (1966). Occasionally exported as an aquarium fish, Weitzman et al. (2001) and Bork & Mayland (1998).

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=0.00631 (0.00271 - 0.01467), b=3.08 (2.88 - 3.28), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Nivel trófico (Ref. 69278): 3.3 ±0.40 se; based on food items.

Resiliencia (Ref. 120179): Alto, población duplicada en un tiempo mínimo inferior a 15 meses (tm=0.5-58, Fec=50-70).

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