Etymology: Acheilognathus: Greek, a = without + Greek, cheilos = lip + Greek, gnathos = jaw (Ref. 45335); tabira erythropterus: From the Latin adjective 'erythropterus' ('erythro' = red, 'pterus' = fin), referring to the nuptial color of males.

Bayesian length-weight: a=0.01259 (0.00444 - 0.03571), b=3.06 (2.82 - 3.30), based on LWR estimates for this Subfamily-body shape (Ref. 93245
Trophic Level (Ref. 69278
): 2.3 ±0.1 se; Based on size and trophs of closest relatives
Resilience (Ref. 69278
