Abstract: A new species of Hypostomus Lacépède is described from the rio Paraguaçu basin, Bahia State, Brazil. The new species is distinguished from its congeners by having black and conspicuous dots on a pale background, which are similar in size on the head, trunk, and fins, along with ventral surface of head and abdomen naked or the latter plated exclusively on its anterior portion, absence of ridges on head and trunk, and caudal-fin lobes relatively similar in length. The new species further differs from the sympatr… Show more

“…Parotocinclus nandae is apparently endemic from the Paraguaçu river basin. The possible strongly endemic nature of the Rio Paraguaçu ichthyofauna was already recorded by Zanata et al [29], Lima & Gerhard [30], Santos & Zanata [31], Birindelli et al [32], Santos & Caramaschi [33], and Pereira et al [20].…”

“…Parotocinclus nandae is morphologically most similar to P. adamanteus, P. doceanus, P. jimi, and P. maculicauda in a series of features, including the shared standard length similar (max. 60 mm), number of vertebrae (28)(29)(30), plates in median lateral series (24)(25)(26)(27), and plates between anal and caudal fins (11)(12). However, the new species is easily distinguished from…”

“…No entanto, até pouco tempo, o conhecimento desta diversidade não era uniformemente distribuído no território nacional, sendo a ictiofauna dulcícola da região Nordeste do Brasil uma das menos conhecidas (Langeani et al 2009). Nas últimas décadas, este quadro vem mudando, com recentes trabalhos publicados sobre a diversidade de peixes de água doce desta região (Ramos et al 2005;Burger et al 2011;Camelier e Zanata 2014;Ramos et al 2014;Paiva et al 2014;Silva et al 2014;Silva et al 2015;Lima et al 2017;Ramos et al 2018) assim como novas espécies descritas (Vari et al 2010;Zanata e Serra 2010;Zanata et al 2013;Costa et al 2010;Ramos et al 2013;) e novos registros (Sarmento-Soares et al 2016). Paiva (1995) afirmou que a fauna de peixes é bastante depauperada nas bacias hidrográficas situadas entre os rios Parnaíba e São Francisco, compreendendo apenas cerca de 50 espécies e indica as condições ambientais adversas como principal causa da baixa diversidade.…”
