Short description
Morfologi | Morfometri
Mjukstrålar i ryggfenan (totalt): 9-10; Mjukstrålar i analfenan: 17 - 19; Ryggkotor: 33 - 34. Differs from all other species of the genus by the following characters: small size (less than 3.1 cm SL vs. larger than 3.5 cm SL), presence of dark lateral band (vs. absent); flat dorsal edge of the orbit and flat ventral edge of the upper (vs. convex); unequal jaws with the superior jaw longer than the inferior (vs. jaws equal); and mouth subterminal (vs. terminal). Can also be differentiated by its long pelvic fins, reaching the anal-fin origin (vs. short and ends not reaching anal-fin origin), 33-34 vertebrae (vs. 37-43) and 14-16 branched anal fin rays (vs. 21-28).

Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00813 (0.00372 - 0.01775), b=3.09 (2.90 - 3.28), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
Trofisk nivå (Ref.
69278): 3.0 ±0.4 se; based on size and trophs of closest relatives
Resiliens (Ref.
120179): Hög, lägsta populationsfördubblingstid mindre än 15 månader (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
59153): Low vulnerability (10 of 100).
