The new species Pareiorhina hyptiorhachis belongs to a genus of armored catfishes native to South America where and found only in Brazil. These peculiar fish get their name from their strange elongated mouth barbels that remind of cat's whiskers. The new species is distinguished from others species of the genus by the presence of a conspicuous ridge on the trunk posterior to the dorsal fin (postdorsal ridge). The description of the diminutive new species was published in the open access journal Zookeys.
