Abstract:
A phylogenetic study of the Loricariidae with emphasis on the Neoplecostominae is presented based on a maximum parsimony
analysis of 268 phenotypic characters encompassing osteology, arthrology, and external morphology. Results support
previous hypotheses of the monophyly of the Neoplecostominae and each of the included genera: Hirtella,
Isbrueckerichthys, Kronichthys, Neoplecostomus, Pareiorhaphis, and Pareiorhina. In addition, previously undiscovered
diversity was revealed within the subfamily as an additional genus-level taxon, herein described as Euryochus. Relationships
among neoplecostomine genera are: (Kronichthys (Euryochus ((Hirtella + Pareiorhaphis) (Pareiorhina (Isbrueckerichthys
+ Neoplecostomus))))). Additional undescribed diversity was also detected among most neoplecostomine genera
and the Hypoptopomatinae. In addition, recently discovered genera Nannoplecostomus and Microplecostomus were included
in the analysis, and were identified as sequential sister-taxa to Neoplecostominae + Hypoptopomatinae, which are
currently not included in any subfamily and regarded as incertae sedis in Loricariidae. The three species of Lithogenes
were included in an encompassing phylogenetic analysis for the first time, and were identified as a monophyletic unit and
sister group to all remaining loricariids. The other loricariid subfamilies were also corroborated as monophyletic, and presented
the following interrelationships (Lithogeninae (Delturinae (Loricariinae (Hypostominae (Nannoplecostomus (Microplecostomus
(Hypoptopomatinae + Neoplecostominae). The Neoplecostominae and its genera are phylogenetically
diagnosed, and hypothesized relationships are compared to those of previous morphological and molecular phylogenetic
studies.
