Pseudancistrus

Pseudancistrus is a genus of suckermouth armored catfishes native to South America.

==Taxonomy== Pseudancistrus is a genus in the tribe Ancistrini of the subfamily Hypostominae. It was described by Pieter Bleeker in 1862, and redescribed by Jonathan Armbruster in 2004. Currently, there are 19 recognized species distributed in northern South America, with the inclusion of the genera Lithoxancistrus, the species formerly known as Hemiancistrus megacephalus, as well as the recently described Pseudancistrus corantijniensis. There is no single morphological feature which distinguishes the group from related genera. Despite this, Pseudancistrus is generally recognized as a monophyletic group.
