The complete mitochondrial genome data of the native, undescribed Tor sp. (Actinopterygii: Cyprinidae) from Sabah, East Malaysia

The genus Tor , commonly recognized as mahseers, encompasses a diverse group of large cyprinid fish that are ecologically and economically important in South and Southeast Asian freshwater ecosystems. This study reports the first complete mitochondrial genome of the native, undescribed Tor sp. isolated from Tambunan, Sabah, East Malaysia. Measuring 16,579 bp, the mitochondrial genome exhibits a GC content of 43.48% and comprises 13 protein-coding genes, 22 tRNAs, two ribosomal RNAs, and a D-loop control region. All genes are arranged in a typical vertebrate mitochondrial pattern. Furthermore, maximum-likelihood phylogenetic analysis, incorporating a broad range of cyprinids and other Tor species, provided crucial insights into the precise phylogenetic placement of the undescribed Sabah Tor sp. as a distinct species within its genus and confirmed its robust affiliation with the family Cyprinidae. This study provides valuable genomic resources (GenBank accession no. PV837872) for future research on the phylogeny, evolution, and conservation of Tor species in Southeast Asia, particularly aiding in the resolution of their complex taxonomy.
