Breve descrizione
Chiavi di identificazione | Morfologia | Morfometria
Spine dorsali (totale) : 2; Raggi dorsali molli (totale) : 7; Raggi anali molli: 5. Distinguished from all congeners, except Hypostomus carinatus (Steindachner, 1881), H. hoplonites Rapp Py-Daniel, 1988 and H. watwata Hancock, 1828, by having five to eight (mode seven) predorsal plates limiting the posterior border of the supraoccipital bone (vs. one to three plates). Can be diagnosed from Hypostomus carinatus, H. hoplonites, and H. watwata by having pale spots against darker ground color on body and fins (vs. dark spots against lighter ground color) (Ref. 93220).
Body shape (shape guide): elongated.
Facultative air-breathing in the genus (Ref. 126274); Occurs in rivers with turbid water, rocky and sandy substrate, and various remnant riparian vegetation. Sympatric with Squaliforma cf. emarginata (Valenciennes, 1840), Hypostomus faveolus, Hypostomus cf. plecostomus (Linnaeus, 1758), H. pyrineusi (Miranda Ribeiro, 1920), and another putative undescribed species of Hypostomus (Ref. 93220).
