पृष्ठीय सौफट रेज़ (सम्पूर्ण) : 5 - 6; ऐनल सौफट रेज़: 7 - 8; जानवरों की रीड़ का जोड़: 27. Absence of an expanded upper tip of the cleithrum, a plesiomorphic condition that distinguishes this species from its congeners; anterior portion of supraorbital, postorbital and upper portion of preopercular canals closed; pelvic fin of males short, tip reaching base of third anal-fin ray; anal fin of males rounded and short, tip reaching a vertical through middle of dorsal-fin base; mesethmoid rounded; anterodorsal process of opercle short; ventral process of posttemporal elongate; branchiostegal rays 5; rostral cartilage present.

Feeds on autochthonous micro-algae and detritus in a swamp (Urubaxi, Brazil) and on allochthonous invertebrates and detritus in an island lake (Buiú-Açu, Brazil).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5312 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00537 (0.00207 - 0.01392), b=3.09 (2.87 - 3.31), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 2.5 ±0.19 se; based on food items.

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