摘要：

A new species of the hypoptopomatine loricariid genus Parotocindus 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.
