“…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.…”

A new species of Jupiaba Zanata is described from tributaries of the rio Aripuanã, rio Madeira basin, Amazonas and Mato Grosso States, Brazil. The new species can be diagnosed from its congeners (except J. abramoides, J. anteroides, and J. poranga) by having two vertically-elongated humeral blotches, the anterior usually with a darker median portion forming an horizontally-elongated trace pointed anteriorly, and a well defined dark longitudinal line extending from the second humeral blotch to the caudal peduncle. The new species differs from J. abramoides, J. anteroides, and J. poranga by having an elongated blotch over caudal peduncle that extends to the distal tip of the caudal-fin median rays. Also, it can be distinguished from most congeners by the combination of relatively high number of lateral line scales, predorsal median line without a series of scales, dentary teeth decreasing abruptly in size towards posterior portion, and presence of a larger central teeth cusp.Uma nova espécie de Jupiaba Zanata é descrita de afluentes do rio Aripuanã, bacia do rio Madeira, Estados do Amazonas e Mato Grosso, Brasil. A nova espécie é diagnosticada de suas congêneres (exceto J. abramoides, J. anteroides e J. poranga) por apresentar duas manchas umerais alongadas verticalmente, a anterior usualmente com porção mediana mais escura formando um traço horizontalmente alongado, com projeção anterior, e uma linha escura bem definida estendendo-se da segunda mancha umeral até o pedúnculo caudal. A nova espécie difere de J. abramoides, J. anteroides, e J. poranga pela presença de uma mancha alongada sobre o pedúnculo caudal, que se estende até o final dos raios caudais medianos. Também pode ser diagnosticada da maioria das congêneres pela combinação de número relativamente alto de escamas na linha lateral, linha mediana pré-dorsal sem uma série de escamas, dentes do dentário decrescendo abruptamente em tamanho posteriormente e dentes com uma cúspide central maior que as demais.

“…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.…”

This work assessed freshwater fishes collected at 12 stations located along the Tarumã River, middle Machado River, Madeira River basin. The fieldwork took place in May and September 2015 during the high and low water seasons, respectively. We gathered 1,482 specimens representing seven orders, 30 families, 54 genera and 74 species using seine, gill, and hand nets. The family Characidae was the most representative, exhibiting the highest number of species captured. The species with the greatest abundance were Hemigrammus vorderwinkleri, Hyphessobrycon bentosi, Hemigrammus cf. bellottii, Bryconella pallidifrons, and Apistogramma resticulosa. Two species that remained unidentified are probably a new species. This study represents the third fish survey totally conducted at a Conservation Unit in the Rondônia State, and will certainly provide valuable information for future investigations on biodiversity conservation in the Machado River.

“…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).…”

Geophagus mirabilis, new species, is endemic to the rio Aripuanã drainage upstream from Dardanelos/Andorinhas falls. The new species is distinguished from all other species of the genus by the presence of one to five large black spots arranged longitudinally along the middle of the flank, in addition to the black midlateral spot that is characteristic of species in the genus and by a pattern of iridescent spots and lines on the head in living specimens. It is further distinguished from all congeneric species, except G. camopiensis and G. crocatus, by the presence of seven (vs. eight or more) scale rows in the circumpeduncular series below the lateral line (7 in G. crocatus; 7-9 in G. camopiensis). Including the new species, five cichlids and 11 fish species in total are known only from the upper rio Aripuanã, and 15 fish species in total are known only from the rio Aripuanã drainage.Geophagus mirabilis, espécie nova, é endêmica da drenagem do rio Aripuanã, a montante das quedas de Dardanelos/ Andorinhas. A espécie nova se distingue de todas as outras espécies do gênero pela presença de uma a cinco manchas pretas grandes distribuídas longitudinalmente ao longo do meio do flanco, em adição à mancha preta no meio do flanco característica das espécies do gênero, e por um padrão de pontos e linhas iridescentes sobre a cabeça em espécimes vivos. Além disso, se distingue de todas as espécies congêneres, exceto G. camopiensis e G. crocatus, pela presença de sete (vs. oito ou mais) séries de escamas na série circumpeduncular abaixo da linha lateral (7 em G. crocatus; 7-9 em G. camopiensis). Com a espécie nova existem cinco ciclídeos, e ao todo 11 espécies de peixe conhecidas somente do alto rio Aripuanã, e ao todo 15 espécies de peixe conhecidas apenas da bacia do rio Aripuanã.
