Ancistrini is a tribe of catfishes (order Siluriformes) of the family Loricariidae.
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. Pterygoplichthyini
to the tribe Ancistrini, which shares the derived
presence of an evertible patch of plates on the cheek.
Most Ancistrini species (except for some Pseudancistrus
) can be separated from all other loricariids except the Pterygoplichthyini by the presence of evertible cheek plates with hypertrophied odontodes
