Length type refers to the length to the end of anal fin (LEA), measured as the distance from tip of snout to posterior end of anal fin base (Ref. 76853). Giora, J., L.R. Malabarba and W.

Differs further from other species of the genus by the following characters: caudal filament length 17.3-35.2% of LEA; pectoral fin ray length 4.1-5.8% of LEA; body depth 8.8-12.2% of LEA; snout length 20.7- 30.0% of HL; gape width 9.5- 16.5% of HL; interorbital distance 22.7-35% of HL; branchial aperture 16.5-26% of HL; head width at operculum 48.4-65% of HL; head width at eyes 31.3-45.6% of HL; number of anal fin rays 155-198; upper jaw equal to lower jaw (Ref. 76853).Description: A vii-xii,148-186; P i-ii,13-15 (Ref. 76853).
