Abstract
Pareiorhaphis nasuta, a new neoplecostomine catfish of the family Loricariidae is described. The species was collected from headwaters of the rio Matipó, tributary of the upper rio Doce basin in State of Minas Gerais, Brazil. The new species is readily diagnosed from all remaining congeners by the longer snout and by the smaller orbital diameter. The new species is the first representative of the genus Pareiorhaphis discovered in the rio Doce basin, thus expanding its geographic distribution. A phylogenetic diagnosis for Pareiorhaphis is presented.
Highlights
Pareiorhaphis Miranda Ribeiro, 1918 is the most diverse genus in the subfamily Neoplecostominae, comprising 17 valid species (Pereira, 2005)
Most species of Pareiorhaphis are distributed in the coastal basins of southern, southeastern, and northeastern Brazil, with highest species diversity observed in coastal rivers of Santa Catarina State, from the rio Araranguá basin north to the rio São João
Pereira (2005) described a new species of Pareiorhaphis, P. parmula, that has one, or rarely two, platelets on each side of the pectoral girdle, just posterior to the gill openings. Pareiorhaphis nasuta shares this feature with P. parmula and have two or three small plates in the same region
Summary
Pareiorhaphis Miranda Ribeiro, 1918 is the most diverse genus in the subfamily Neoplecostominae, comprising 17 valid species (Pereira, 2005). These fishes are small to medium-sized suckermouth armored catfishes with maximum standard length between 34 mm (P. nudulus) and 116 mm (P. azygolechis). During the last five years, six new species have been described, which are currently assigned to Pareiorhaphis (Pereira & Reis, 2002 and Pereira, 2005). In recent fish collections made in headwater tributaries of the rio Doce basin, in Minas Gerais State, additional specimens of Pareiorhaphis were collected and discovered to belong to an undescribed species. The present work reports the first record of a Pareiorhaphis species in the rio Doce drainage and again expands the distribution of the genus
