Pareiorhaphis is a genus of catfish in the family Loricariidae native to South America. This genus can be readily distinguished from other neoplecostomines by the unique combination of having fleshy lobes on lateral margins of head ornamented with hypertrophied odontodes on nuptial males, caudal peduncle ovoid in cross section, abdomen usually naked, dorsal fin spinelet ovoid and adipose fin usually present. The color pattern is usually dark brown and mottled with the abdomen white. Most species in to Pareiorhaphis were originally described in Hemipsilichthys. In 1918, AlÃÂpio de Miranda-Ribeiro proposed the new genus Pareiorhaphis. Whether Pareiorhaphis is monophyletic or not is currently unknown.
