Issue
Synonymy based on examination of numerous specimens including syntypes of Ancistrus dolichopterus; no recent redescription, but see Eigenmann and Eigenmann (1890:448, as Ancistrus temminckii) for a complementary description, and Römer (1990) and Holota (1990) (both references as Ancistrus cf. hoplogenys) for figures of living specimens and reproduction observations in aquarium; 12S and 16S mitochondrial rRNA gene sequences used in molecular phylogenies by Montoya-Burgos et al. (1997: fig. 4; 1998: figs. 3 & 6; EMBL/GenBank Y08276; Y08324).
