Taxonomy

Loricariinae was first described in 1831. Later, in 1979, many genera were described and Loricariinae was divided into four subfamilies: Loricariini, Harttiini, Farlowellini, and Acestridiini. Eventually, the genera of Acestridiini was included under

Hypoptopomatinae The Hypoptopomatinae are a subfamily of catfishes (order Siluriformes) of the family Loricariidae, composed of 17 genus, genera and approximately 80 species. This subfamily represents about one-tenth of all loricariid species. It has been divide ...

and genera of Farlowellini was reclassified into Hartiini. This subfamily has been found to be monophyletic. The most recent papers conclude that there are 30 or 31 genera; the status of ''Cteniloricaria'' is dubious; although recognized as a synonym of '' Harttia'' by some, this conclusion was reached without diagnosing the

type species In zoological nomenclature, a type species (''species typica'') is the species name with which the name of a genus or subgenus is considered to be permanently taxonomically associated, i.e., the species that contains the biological type specime ...

Description

As loricariids, loricariinae species are characterized by a depressed body covered by bony plates, a unique pair of maxillary barbels, and modification of the mouth into a

suckermouth In fish, a suckermouth is a ventrally-oriented (inferior) mouth adapted for grazing on algae and small organisms that grow on submerged objects. All Loricariidae possess a suckermouth as do the cypriniform algae eaters of the genus ''Gyrinocheilus' ...
