Pseudoloricaria laeviuscula is the only species of the monotypic genus Pseudoloricaria, a genus of the family Loricariidae of catfish (order Siluriformes).[2] The phylogenetic position of Pseudoloricaria is uncertain.[2]
This species is endemic to Brazil where it is found in the middle and lower Amazon basin, including the Negro and Branco Rivers.[2][3] P. laeviuscula is found over sandy bottoms, in clear waters, in the main flow of rivers, and in neighboring temporary ponds.[2]
Pseudoloricaria laeviuscula reaches a length of 30.5 centimetres (12.0 in) SL.[3] Although reproductive habits are unknown, this species is probably a lip brooder.[2] Sexual dimorphism includes hypertrophied development of the lower lip suggesting that P. laeviuscula is a lip brooder.[2] This species shows derived features such as a reduction in size and number of teeth, premaxillary teeth absent, a circular head shape, and eyes reduced in size without iris operculum.[2]
