Background/Objectives: In this study, we report the complete mitochondrial genome sequence of
Hoplisoma concolor Weitzman, 1961 (Siluriformes: Callichthyidae), a callichthyid catfish.
Methods: DNA sequencing was performed to obtain its complete mitogenome using the HiSeq platform. To assess the phylogenetic relationships, maximum-likelihood and Bayesian inference phylogenetic trees were constructed using two ribosomal RNA (rRNA) genes and all protein-coding sequences (PCGs) concatenated from the
H. concolor mitogenome, along with 31 other Siluriformes mitogenomes.
Results: The complete mitogenome of
H. concolor is 16,579 base pairs in length, with a nucleotide composition of 32.2% A, 26.0% T, 15.3% G, and 26.5% C. It contains 13 PCGs, 22 transfer RNA genes, and 2 rRNA genes. Phylogenetic analysis based on all PCGs and two rRNAs of the complete mitogenome confirms
H. concolor as a sister species of
H. panda within the subfamily Corydoradinae. In addition, intergenic sequences between
atp6 and
cox3 of 21 species of Corydoradinae provide further support for their phylogenetic relationship.
Conclusions: Given the lack of detailed descriptions regarding the length and nucleotide composition of these intergenic sequences, our study contributes valuable insights into the genetic diversity and evolutionary complexity of Callichthyidae.
