Abstract:
The family Callichthyidae comprises eight genera of fishes widely distributed across the Neotropical region. In the present study,
sequences of the mitochondrial genes 12S rRNA, 16S rRNA, ND4, tRNAHis, and tRNASer were obtained from 28 callichthyid
specimens. The sample included 12 species of Corydoras, three species of Aspidoras, two species of Brochis, Dianema, Lepthoplosternum,
and Megalechis, and two local populations of Callichthys and Hoplosternum. Sequences of Nematogenys inermis (Nematogenyidae),
Trichomycterus areolatus, and Henonemus punctatus (Trichomycteridae), Astroblepus sp. (Astroblepidae), and
Neoplecostomus paranensis, Delturus parahybae, and Hemipsilichthys nimius (Loricariidae) were included as the outgroup. Phylogenetic
analyses were performed by using the methods of maximum parsimony and maximum likelihood. The results of almost all
analyses were very similar. The family Callichthyidae is monophyletic and comprises two natural groups: the subfamilies Corydoradinae
(Aspidoras, Brochis, and Corydoras) and Callichthyinae (Callichthys, Dianema, Hoplosternum, Lepthoplosternum, and
Megalechis), as previously demonstrated by morphological studies. The relationships observed within these subfamilies are in
several ways different from those previously proposed on the basis of morphological data. Molecular results were compared with the
morphologic and cytogenetic data available on the family.
