Etymology: Parotocinclus: Greek, para in the side of + greek, ous, otis = ear + Greek, kygklos, ou = a fish (Ref. 45335); seridoensis: The specific name seridoensis refers to the semiarid Caatinga region, popularly known as 'Sertão do Seridó', which encompasses the upper rio Piranhas-Açu basin region in Rio Grande do Norte and Paraíba States, one of the most arid regions in northeastern Brazil, with mean annual rainfall of about 500 mm. 'Seridó' is probably derived from the native Indian language expression 'ceri-toh'. In Tapuia language it means 'little foliage and little shade', in reference to the characteristic Caatinga vegetation, mainly composed by xeric shrub lands and thorn forest, that consists in small, thorny trees that shed their leaves in the dry periods.
