Descrição suscinta
Chaves de identificação | Morfologia | Morfometria
Raios dorsais (total) : 12; Raios anais : 10; Vértebras: 37. Leporinus torrenticola can be diagnosed from all other species of anostomids except Hypomasticus julii, H. megalepis, H. pachycheilus, Leporinus gomesi, L. granti, L. multimaculatus, L. nijsseni, and L. santosi by the possessing one dark blotch on midline of anterior portion of the flank (between opercle and pelvic-fin origin) surrounded by five to seven dark blotches (vs. anterior portion of flank with dark longitudinal stripes, or with dark transversal bars, or with dark blotches not forming the aforementioned pattern). Leporinus torrenticola differs from Hypomasticus julii, H. pachycheilus, Leporinus gomesi, L. granti, L. nijsseni, and L. santosi, by possessing three teeth on premaxilla (vs. four), and subinferior mouth (vs. inferior in Hypomasticus julii and H. pachycheilus, and terminal in Leporinus gomesi, L. granti, L. nijsseni, and L. santosi); and from H. megalepis by having 37-40 lateral-line scales (vs. 33 -35), and from L. multimaculatus by having 16 scale rows around caudal peduncle (vs. 12) (Ref. 117595).
Body shape (shape guide): fusiform / normal.
Prefers to inhabit moderate to fast flowing waters of the rapids of the rio Xingu and rio Iriri, where it is often collected alongside specimens of Hypomasticus julii. Considered omnivorous, feeding mainly on aquatic insects, filamentous algae and Podostemaceae (Ref. 117595).
