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 .: elongated.
