Short description
Identification keys | Morphology | Morphometrics
Can be distinguished from all other species in the genus by lacking scaly sheath along the dorsal fin base, and from all except Geophagus taeniopareius by retaining a prominent dark stripe from the eye to the corner of the preopercle as adult. Differs from G. Taeniopareius by (1) distinct light spots on the middle and upper part of the caudal fin, (2) lack of horizontal stripes along the sides, (3) wider lips, (4) lack of microbranchiospines and (5) lower meristics: modally D. XV1.11 instead of XVII. 11 , E1 row scales 30 instead of 32, and vertebrae 14+17 instead of 14+18 (Ref. 57764).

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=0.01000 (0.00244 - 0.04107), b=3.04 (2.81 - 3.27), in cm total length, based on all LWR estimates for this body shape (Ref.
93245).
Trophic level (Ref.
69278): 2.5 ±0.1 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.
