Neotype designation of Acipenser plecostomus in Boeseman 1968 (RMNH 182400) may be invalid if the smallest specimen in NRM LP 32 is part of the type series; for more details on synonymy of Hypostomus plecostomus see Boeseman (1968:32) and Isbrücker (1980:30). 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 AJ318351).
