Etymology: Hypostomus: Greek, hypo = under + Greek, stoma = mouth (Ref. 45335); heraldoi: Named for Heraldo Antônio Britski, Museu de Zoologia da Universidade de São Paulo, for his extensive contributions to the knowledge of neotropical fish diversity.
Eponymy: Dr Heraldo Antonio Britski is a Brazilian ichthyologist who was awarded a bachelor’s degree (1960) and a doctorate (1973) by Universidade de São Paulo where he is still a researcher, even though he is officially retired. [...] (Ref. 128868), visit book page.

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, except Hypostomus albopunctatus, by having the pectoral fin spine length equal to or smaller than the pelvic-fin spine. Can be differentiated from Hypostomus albopunctatus by the presence of roundish dark spots on body and fins (vs. pale), and generally having more premaxillary, 39-59 per ramus (Ref. 79067).
Body shape (shape guide): elongated.
Facultative air-breathing in the genus (Ref. 126274); Occurs in turbid water and rocky substrate with sand (Ref. 79067). Syntopic with Hypostomus ancistroides, Hypostomus iheringii, Hypostomus margaritifer, and Hypostomus regani (Ref. 79067).
