Short description
Identification keys | Morphology | Morphometrics
Diagnosed from all species of Hypostomus, except H. levis, by lacking adipose fin. Differs from H. levis mainly by having bifid teeth, with mesial cusp large and rounded, and lateral cusp small and pointed; 23-42 premaxillary and 25-42 dentary teeth; black spots on body. Can be separated from all species of Hypostomus in the La Plata basin (except H. ancistroides, H. angipinnatus, H. aspilogaster, H. borellii, H. boulengeri, H. brevis, H. commersoni, H. cordovae, H. denticulatus, H. dlouhyi, H. fluviatilis, H. heraldoi, H. hermanni, H. isbrueckeri, H. laplatae, H. latifrons, H. mutucae, H. nigromaculatus, H. peckoltoides, H. piratatu, H. topavae, H. uruguayensis, and H. variostictus) by the presence of darker spot on body.
Facultative air-breathing in the genus (Ref. 126274)
