Abstract: A new species of Gladioglanis is described from a single locality on rio Aripuanã, rio Madeira basin, and can be distinguished from its congeners by the following characters: dorsal-fin spine and spinelet absent, first dorsal-fin ray flexible, unbranched, followed by five branched dorsal-fin rays, pectoral-fin spine short and with few (5 anterior-side, 4 posterior-side) dentations, 22-25 anal-fin rays, round profile of the head in dorsal view, first dorsal-fin pterygiophore in contact with the neural spine of … Show more

“…The apparently high degree of endemism of the area was already discussed elsewhere, with about ten endemic described species suggested by Kullander (1995) and Benine (2002). Recent collecting efforts resulting from various inventory projects carried out on rio Aripuanã drainage continuously reveal new and possibly endemic fish species (Rocha et al, 2008a(Rocha et al, , 2008bpresent paper), attesting the importance of new investigations of its ichthyofauna and conservation of the area.…”

“…The current work contributed 24 species to the general inventory of the Machado River and 26 species to the inventory conducted in Conservation Units in the Rondônia State. Additionally, the material deposited in the Brazilian collections enabled the accomplishment of recent taxonomic studies, which contributed to enhancing the knowledge of the ichthyofauna of both the Madeira River (Rocha et al 2008a, Rocha et al 2008b, Zanata & Ohara 2009, Ribeiro et al 2011, Ohara 2012, Marinho & Ohara 2013, Zanata & Ohara 2015, Ohara & Lima 2015a, Tencatt & Ohara 2016a, Ohara & Neuhaus 2016, Pastana & Ohara 2016, and the Machado River (Ohara & Lima 2015b, Ohara & Marinho 2016.…”

“…A species overlooked by Kullander (1995), Utiaritichthys longidorsalis Jégu, Tito de Morais & Santos (Serrasalmidae), and the recently described Trachycorystes menezesi Britski & Akama (Auchenipteridae) and Hypostomus dardanelos Zawadzki & Carvalho (Loricariidae) should be added to the list, changing the number of valid species considered endemic to that region to 11, including Geophagus mirabilis (Jégu et al, 1992;Britski & Akama, 2011;Zawadzki & Carvalho, 2014). If we consider all of the species thought to be endemic to the rio Aripuanã basin as a whole, the number rises to at least 15 (Rocha et al, 2008a(Rocha et al, , 2008bZanata & Ohara, 2009;Ribeiro et al, 2011;Eschmeyer, 2014). The fish fauna of the upper rio Aripuanã may be more closely related to that of the adjacent rio Tapajós headwaters.…”

“…The rio Aripuanã is a major right bank tributary of the lower rio Madeira, and the Dardanelos falls mark its entry into the Madeira floodplain. Although it has been little explored, many works recorded species of fishes in the upper rio Aripuanã (e.g., Kullander, 1990Kullander, , 1995Rocha et al, 2008aRocha et al, , 2008b, and the fish fauna is distinct from that from the rio Madeira proper and the floodplain portion of the rio Aripuanã, as reported by Rapp Py- Daniel et al (2007). The Geophagus from the rio Aripuanã was exported for the ornamental fish market in 2011 and has been cultivated in aquaria in Europe and North America (Gottwald, 2011).…”
