Taxonomic Remarks
Specimens collected in Paraguay (middle Paraguayan Parana basin) identified as Hypostomus albopunctatus based on morphology ( Weber et al. 1992:13). Mitochondrial D-loop sequences used in a molecular phylogeny of Hypostomus and related genera by Montoya-Burgos and Weber (in press, fig 2; EMBL/GenBank AJ318379).

Dorsale stekels (totaal) : 2; Dorsale zachte stralen (totaal) : 7; Anale zachte stralen: 6. Diagnosed from all other congeners except Hypostomus heraldoi by the pelvic-fin unbranched ray length equal to or greater than pectoral-fin unbranched ray (vs. pelvic-fin unbranched ray shorter than pectoral-fin unbranched ray). Differs from H. heraldoi by having pale dots over body and fins (vs. dark dots over body and fins) (Ref. 91066).
Body shape (shape guide): elongated.
Facultative air-breathing in the genus (Ref. 126274)
