Mjukstrålar i ryggfenan (totalt) : 10 - 11; Mjukstrålar i analfenan: 49 - 53. Fewer lateral line scales (58-59, versus 64-70 in G. maracaiboensis and 68-75 in G. atratoensis), fewer scale rows between lateral line and anal-fin origin (9-11, versus 12-14 in G. maracaiboensis and 13-16 in G. atratoensis) and fewer scale rows around caudal peduncle (19, versus 21-23 in G. maracaiboensis and 21-23 in G. atratoensis).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.6250 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01202 (0.00477 - 0.03032), b=2.99 (2.77 - 3.21), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trofisk nivå (Ref. 69278): 4.0 ±0.7 se; based on size and trophs of closest relatives

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