Data from: Molecular phylogeny of the highly diversified catfish subfamily Loricariinae (Siluriformes, Loricariidae) reveals incongruences with morphological classification

The Loricariinae belong to the Neotropical mailed catfish family
Loricariidae, the most species-rich catfish family. Among loricariids,
members of the Loricariinae are united by a long and flattened caudal
peduncle and the absence of an adipose fin. Despite numerous studies of
the Loricariidae, there is no comprehensive phylogeny of this
morphologically highly diversified subfamily. To fill this gap, we present
a molecular phylogeny of this group, including 350 representatives, based
on the analysis of mitochondrial and nuclear genes (8426 positions). The
resulting phylogeny indicates that Loricariinae are distributed into two
sister tribes: Harttiini and Loricariini. The Harttiini tribe, as
classically defined, constitutes a paraphyletic assemblage and is here
restricted to the three genera Harttia, Cteniloricaria, and Harttiella.
Two subtribes are distinguished within Loricariini: Farlowellina and
Loricariina. Within Farlowellina, the nominal genus formed a paraphyletic
group, as did Sturisoma and Sturisomatichthys. Within Loricariina,
Loricaria, Crossoloricaria, and Apistoloricaria are also paraphyletic. To
solve these issues, and given the lack of clear morphological diagnostic
features, we propose here to synonymize several genera (Quiritixys with
Harttia; East Andean members of Crossoloricaria, and Apistoloricaria with
Rhadinoloricaria; Ixinandria, Hemiloricaria, Fonchiiichthys, and Leliella
with Rineloricaria), to restrict others (Crossoloricaria, and
Sturisomatichthys to the West Andean members, and Sturisoma to the East
Andean species), and to revalidate the genus Proloricaria.
