Descrição breve
Chaves de identificação | Morfologia | Morfometria
Espinhos dorsais (total) : 1; Raios dorsais moles (total) : 6; Espinhos anais: 0; Raios anais moles: 12; Vértebras: 39. Rhamdia jequitinhonha is diagnosed from its congeners by a unique set of character states: pectoral fin spine with serrations on both sides; head sensory canals multiple; few caudal fin upper lobe procurrent rays (10); adipose fin 34.7% of SL or 141% of HL; free post-Weberian vertebrae, 39; maxillary barbels 39.2% of SL or 159% of HL; caudal fin lower lobe slightly the longer; color pattern uniform with faint lateral stripe, no apparent irregular blotches, or dark saddle-like marking across nape.
