Clés d'identification | Morphologie | Morphométrie
Épines dorsales (Total) : 1; Rayons mous dorsaux (Total) : 7; Épines anales: 1; Rayons mous anaux: 4. Differs from all other species of the genus Hypostomus, except Hypostomus multidens and Hypostomus ternetzi, by the possession of more than 115 teeth (vs. less than 109) per ramus on dentary and premaxilla. Can be separated from Hypostomus ternetzi by having 116-214 teeth per jaw ramus, mean 167 (vs. 39-127 teeth per ramus, mean 81.4); body with beige to light-brown color (vs. dark brown); larger orbital diameter, 18.5 to 21.2% of HL (vs. 14.5 to 16.1% ); abdomen naked vs. abdomen partially plated; and teeth with two symmetrical cusps vs. two asymmetrical cusps. Can be differentiated from Hypostomus multidens by its dark (vs. pale) spots over body and fins (Ref. 79067).
Facultative air-breathing in the genus (Ref. 126274); Occurs in turbid water and rocky substrates with sand. Syntopic with Hypostomus ancistroides, Hypostomus iheringii, Hypostomus margaritifer, Hypostomus regani, and Hypostomus heraldoi (Ref. 79067).
