Descrição suscinta
Chaves de identificação | Morfologia | Morfometria
Raios dorsais (total) : 5; Raios anais : 3 - 4. This species is distinguished from Pseudexostoma brachysoma and P. longipterus by the following characters: posterior margin of lower lip with 3 notches, depth of middle one the same as lateral ones lateral ones (vs. shallower), length of 2 smaller median lobes of lower lip the same length as lateral lobes (vs. longer); pelvic fin I, 1-5 (vs. I, 3-4); base iof adipose fin shorter, 28.8-39.8% SL (vs. 36.1-46.0); caudal peduncle deeper, depth 6.4-8.3% SL, 32.6-42.7% in length of caudal peduncle (vs. 4.2-6.9 in depth and 20-33.7 in length); premaxillary tooth band with 18-22 teeth (vs. 16-18), it is divided into 2 and are connected partially (vs. isolated) (Ref. 57980).
