“…Despite the intensive and broad collecting efforts in the rio Madeira basin ( i.e ., Casatti et al ., 2013; Costa et al ., 2017; Pedroza et al ., 2012; Queiroz et al ., 2013; Vieira et al ., 2016) and several scientific expeditions conducted by various ichthyologists ( e.g ., researchers from MNRJ, MCP, MZUSP and UFRO) to the rivers draining the Chapada dos Parecis, C. nambiquara was not found in localities other than the igarapé Piolhinho, indicating a restricted distribution. A high number of fish species endemic to the upper Juruena, Madeira and Paraguai basins at Chapada dos Parecis were listed by Ohara and Lima (2015).…”

“…Particularly in the rio Madeira basin, five species of Characidium were described: Characidium barbosai, Flausino‐Junior, Lima, Machado & Melo, C. bolivianum Pearson, Characidium heinianum Zarske & Géry, Characidium schindleri Zarske & Géry and Characidium summum Zanata & Ohara. In addition, various species of Characidium not identified at the species level or with imprecise identification were cited to occur in the Madeira basin ( e.g ., Casatti et al ., 2013; Costa et al ., 2017; Hablützel, 2012; Ohara et al ., 2013; Vieira et al ., 2016). The high number of unidentified and possibly new species of Characidium cited in the literature, allied to the low number of species already described in the Madeira basin, indicates the poor taxonomic knowledge of the genus in that river basin.…”

This study describes Characidium nambiquara, a new species from the upper rio Guaporé, rio Madeira basin, Brazil. The new species differs from most congeners by the presence of isthmus and area between the contralateral pectoral-fin bases completely naked. From congeners with some degree of scaleless ventral surface of the body C. nambiquara differs by having 10 circumpeduncular scales. The new species is also distinguished from congeners by the spotted colour pattern on body of the large-sized specimens and by having black dashes on all fins and conspicuous midlateral longitudinal dark stripe or conspicuous vertical bars absent. Characidium nambiquara further differs from most congeners by the presence of 34-36 pored scales on the lateral line, 3 horizontal scale rows above the lateral line and 3 horizontal scale rows from the lateral line to the midventral scale series. Remarks on intraspecific colour variation within the genus, not related to sexual dimorphism, are also provided.

“…Several inventories in the lower portions of tributaries from rio Madeira in Rondônia ( i.e ., Jaciparaná, Jamari, Cautário, Pacaás Novos, Machado) failed to record O. pacaasnovos was not recorded in localities other than the type locality (cf. Santos, 1996; Queiroz et al ., 2013a,b; Casatti et al ., 2013; Vieira et al ., 2016; Costa et al ., 2017). In the lower portions of these rivers O. fugitiva and O. nareuda also occur (Lima et al ., 2013).…”

A new species of Odontostilbe is described from the rio Jaciparaná, rio Madeira basin, Rondônia, Brazil. Odontostilbe pacaasnovos differs from all its congeners, except O. pequira, by the colour pattern. Additionally, it differs from its congeners by the terminal mouth, number of cusps in the teeth of the premaxilla (5-7), number of branched rays in the anal fin (19-22), by the shape of dentary teeth (5-7 cusps with central cusp larger and longer than laterals cusps) and by the number of lamellae of the olfactory rosette (17-18 in male and 14 in female). Morphological and molecular comparisons corroborate the distinctiveness between O. pacaasnovos and its congeners, justifying its recognition as a new species.

“…The fish were then fixed in a 10% formalin solution and later preserved in 70% ethanol. Taxonomic literature and identification keys were consulted to identify species (Queiroz et al 2013;Vieira et al 2016;Ohara et al 2017). The classification follows Nelson et al (2016).…”

Ichthyofauna associated with sandy beaches of the rio Machado, tributary of the rio Madeira, northern Brazil

The rio Machado is an large tributary of the rio Madeira, and investigations of the ichthyofauna are urgent given the current high threat of habitat loss on account of a hydroelectric plant under construction. Our inventory quantified 9,544 specimens, representing four orders and 38 species. Our study provides an unprecedented list of fish species from a poorly studied South American basin. This basin, which is considered one of the world’s biodiversity hotspots, presents high endemism, few cases of co-existence of phylogenetically related lineages, low species diversity, and few species occurrences with wide distribution.
