This species differs from its congeners by the following characters: blunt, rounded snout and horizontal, subterminal mouth; a large distinct blotch on the upper pectoral-fin base; 13 elements found in both the second dorsal fin and anal fin; first and second dorsal fins not broadly joined; scales large, 28-35 in lateral series; nape naked or with a few rows of scales before the first dorsal fin; most specimens with upper jaw having a single complete row of teeth; first gill arch with 3 triangular gill rakers on the ceratobranchial, 1 at angle and 2 lobular rakers on the epibranchial (Ref. 55435).
Eastern Pacific: Panama and Colombia.
Specimens were collected among reeds at a sandy mud beach (Ref. 55435).

= 0.5078 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01260 (0.00393 - 0.04037), b=2.84 (2.58 - 3.10), based on LWR estimates for this Subfamily-BS (Ref. 93245
Trophic Level (Ref. 69278
): 3.3 ±0.4 se; Based on size and trophs of closest relatives
Resilience (Ref. 69278
): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153
): Low to moderate vulnerability (27 of 100) .
