is a speciose catfish genus from South America with widely investigated phylogenetic and evolutionary relationships. The complete mitogenomes of and were sequenced, assembled, and annotated using next-generation sequencing. The genome arrangements, gene contents, genome structures, base compositions, evolutionary features, codon usage, and tRNA structures of the two mitogenomes were compared and analyzed with nine published mitogenomes of . Phylogenetic analysis was performed using concatenated nucleotide sequences with 13 protein-coding genes and two rRNAs with 44 mitogenomes of Siluriformes. These results provide information on the mitogenomes of eleven species and evolutionary relationships within the suborder Loricarioidei, which may be applicable for further phylogenetic and taxonomic studies on Siluriformes and Loricarioidei.

: , an endemic fish in the Huaihe River basin, is a newly described species with limited molecular genetic research, hindering understanding of its evolutionary status, population structure, and genetic diversity. This study aimed to characterize its complete mitochondrial genome, clarify its phylogenetic position within , and assess its population genetic diversity. : We obtained the complete mitogenome of (sourced from the Zhugan River) through sequencing, followed by detailed annotation of this genomic sequence.

Background/objectives: To date, no information is available on the complete mitochondrial genome of the genus (Siluriformes: Callichthyidae), a callichthyid catfish. In this study, we report on two complete mitochondrial genome sequences of Cope, 1872, and Miranda Ribeiro, 1912, the only two recognized species within the genus .
Methods: DNA sequencing was performed using the HiSeq platform to obtain their complete mitogenomes.

: In this study, we report the complete mitochondrial genome sequence of Weitzman, 1961 (Siluriformes: Callichthyidae), a callichthyid catfish. : 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 mitogenome, along with 31 other Siluriformes mitogenomes.

The order Siluriformes (catfish) is one of the largest groups of fish. Diversity in the body size among its species, which range from a few centimeters to 4 meters, makes Siluriformes an interesting group to investigate the body size evolution. Here, we present the complete mitogenome of Brachyplatystoma filamentosum (Piraíba), the largest Amazonian catfish, to explore the evolutionary history of Siluriformes and their body size dynamics.

Background/objectives: Accipitridae mitogenomes exhibit unique structural variations, including duplicated control regions (CRs) that undergo gradual degeneration into pseudo-CRs, revealing a complex evolutionary landscape. However, annotation of this characteristic in a subset of accipitrid genomes is lacking. Due to the taxonomic diversity of Accipitridae and the presence of understudied species, comprehensive mitogenomic studies are essential.
