TitleRhadinoloricaria gen. nov. and Planiloricaria, two genera of South American Mailed Catfishes (Pisces, Siluriformes, Loricariidae)
AbstractThis paper deals with two genera of loricariid fishes: Rhadinoloricaria gen. nov., and Planiloricaria Isbrücker, 1971. Rhadinoloricaria is established for the species macromystax, described by Günther (1869: 426) in the binomen Loricaria macromystax. Planiloricaria, elevated to generic rank in the present paper, was described by Isbrücker as a subgenus of the genus Pseudohemiodon Bleeker, 1862, for the new species cryptodon (Isbrücker, 1971: 278). Diagnoses of these two monotypic genera are given, together with redescriptions and figures of their type-species. The relationships with other genera within the subfamily Loricariinae are discussed. A provisional subdivision into six genus-groups is given, and a new subfamily name, Acestridiinae, is proposed for the genus Acestridium Haseman, 1911. A key to the genera of the Pseudohemiodongroup (to which Rhadinoloricaria and Planiloricaria are ascribed) is provided.
