Abstract:
Aspidoras comprises 25 species currently considered as valid, being widely
distributed in Brazil, occurring from the upper rio Paraná basin in São Paulo to
coastal basins of Ceará. After Nijssen, Isbrücker’s review more than 40 years ago,
no extensive work regarding the taxonomy of Aspidoras was conducted. Our
paper presents a comprehensive taxonomic revision of the genus, based primarily
on the extensive material that has been collected since then. Considering the new
diagnosis plus the available phylogenetic data, A. pauciradiatus and A. virgulatus
are transferred to Corydoras and Scleromystax, respectively. New synonymies
are proposed: A. eurycephalus and A. taurus with A. albater; A. menezesi and A.
spilotus with A. raimundi; and A. microgalaeus and A. marianae with A. poecilus.
Additionally, a new species from the Araguaia and Paraguay river basins is
described, which can be distinguished from its congeners by the morphology
of its complex vertebra and infraorbital 1. Thereby, the number of valid species
within Aspidoras was reduced from 25 to 18. Redescriptions for A. albater,
A. belenos, A. depinnai, A. fuscoguttatus, A. lakoi, A. maculosus, A. poecilus, A.
psammatides, A. raimundi, and A. velites are provided. An identification key to the
species of Aspidoras is also provided
