Ancistrini is a tribe of catfishes (order Siluriformes) of the family Loricariidae.

Taxonomy

Ancistrini has previously been considered a loricariid subfamily. However, it was realized that the subfamily Hypostominae would be paraphyletic if Ancistrinae continued to be recognized. To continue recognizing the monophyly of this group while returning it to Hypostominae, Hypostominae was broken into several tribes.cite web|url=http://www.auburn.edu/academic/science_math/res_area/loricariid/fish_key/ANCISTRIN/ANCISTRIN.html|title=Ancistrini Kner, 1853 |first=Jonathan W.|last=Armbruster|accessdate=2007-07-16] Pterygoplichthyini is sister to the tribe Ancistrini, which shares the derived presence of an evertible patch of plates on the cheek.cite web|url=http://www.auburn.edu/academic/science_math/res_area/loricariid/fish_key/ptergrp/ptergrp.html|title=Pterygoplichthyini Armbruster 2004|first=Jonathan W.|last=Armbruster|accessdate=2007-07-16]

Description

Most Ancistrini species (except for some "Pseudancistrus" and "Spectracanthicus") can be separated from all other loricariids except the Pterygoplichthyini by the presence of evertible cheek plates with hypertrophied odontodes.
