Abstract

A new species of the hypoptopomatine loricariid genus Parotocinclus is described based on material from the headwaters of the Rio Jequitinhonha, Minas Gerais State, eastern Brazil. The new species is distinguished from all congeners, except P. prata and P. robustus, by the absence of abdominal plates between the pectoral girdle and the anus. It differs from P. prata and P. robustus by having a smaller cleithral width (16.7–20.7 vs. 20.8–27.6% SL in P. prata and 25.9–28.8% SL in P. robustus) in addition to other morphological features.

Uma nova espécie de loricarídeo hypoptomatíneo do gênero Parotocinclus é descrita com base em material das cabeceiras do Rio Jequitinhonha, no estado de Minas Gerais, leste do Brasil. A nova espécie é diferenciada de todos os seus congêneres, exceto P. prata e P. robustus, pela ausência de placas no abdômen entre a cintura peitoral e o ânus. Se distingue das espécies acima pela menor largura cleitral (16.7–20.7 vs. 20.8–27.6% do Comprimento Padrão em P. prata e 25.9–28.8% do Comprimento Padrão em P. robustus), além de outros caracteres morfológicos.
