ABSTRACT
The complete mitogenome of Corydoras nattereri , a species of mailed catfishes from southeastern Brazil, was reconstructed using next-generation sequencing techniques. The mitogenome was assembled using mitochondrial transcripts from the liver transcriptomes of three individuals, and produced a circular DNA sequence of 16,557 nucleotides encoding 22 tRNA genes, two rRNA genes, 13 protein-coding genes and two noncoding control regions (D-loop, OrigL). Phylogeographic analysis of closely related sequences of Cytochrome Oxydase C subunit I (COI) demonstrates high diversity among morphologically similar populations of C. nattereri . Corydoras nattereri is nested within a complex of populations currently assigned to C. paleatus and C. ehrhardti . Analysis of mitogenome structure demonstrated that an insertion of 21 nucleotides between the ATPase subunit-6 and COIII genes may represent a phylogenetically informative character associated with the evolution of the Corydoradinae.
