Auckland: Magnolia Press, n. 1757, p. 31-48, 2008.1175-5326http://hdl.handle.net/11449/22408Neoplecostomus paranensis was the only Neoplecostomus species known from the upper Rio Parana basin, and it was diagnosed from its congeners mainly by the absence or reduction of the adipose fin. In this study we describe three new Neoplecostomus species. All of them are promptly differentiated from N. paranensis by having a well-developed adipose fin. Furthermore, the new species are differentiated from congeners by morphometric and meristic traits, in addition to color pattern. Neoplecostomus paranensis is redescribed. We also provide an identification key to all Neoplecostomus species.31-48engcatfishesFresh waterNeotropicalOstariophysiSiluriformesichthyologyArtigoWOS:000255480300002Acesso restrito4433495820388025
