Etymology: Centromochlus: Greek, kentron = sting + Greek, mochlos, -ou = lever, crowbar (Ref. 45335);  meridionalis: The specific name makes reference to the record of a Centromochlus species in southern Brazilian Amazon, a region referred to as 'Meridional Amazon'. This species is the single species in the genus originally described from Meridional Amazon, and with distribution apparently restricted to this region.

Descrição breve Morfologia | Morfometria

Espinhos dorsais (total): 1; Raios dorsais moles (total): 5; Raios anais moles: 9 - 10; Vértebras: 29. This species can be diagnosed from other species of Centromochlus by having eye diameter less than 16% of Head Length (vs. 20-35%). It differs from C. heckelii, C. existimatus, C. altae, and C. perugiae by absence of anterior nuchal plate (vs. presence); from C. concolor, C. reticulatus, C. macracanthus, C. punctatus, and C. schultzi, by having smooth anterior margin of dorsal spine (vs. with serrae); and from C. romani by a trapezoid quadrate, with metapterygoid in contact with hyomandibula (vs. enlarged quadrate, interposed between metapterygoid and hyomandibula). It can be further distinguished from C. heckelii and C. existimatus by having pectoral-fin spine 20-25% of SL (vs. 29- 42%) and 6 branched anal-fin rays (vs. 4 or 5); and from all congeners, except C. perugiae and C. romani, by having male modified anal fin with enlarged third unbranched ray, about twice thicker than first unbranched ray (Ref. 94696).
