摘要

Synodontis, of great edible and ornamental value, is the most species-rich genus of the catfish family Mochokidae, but comparative studies based on its mitogenome data are still lacking. Therefore, we sequenced and analyzed the complete mitogenomes of Synodontis decorus and Synodontis petricola and compared them with those of other Mochokidae or Synodontis species; these were determined to be 16,574 and 16,529 bp, respectively. A phylogenetic analysis further confirmed the position of Synodontis in Mochokidae and showed that the genus Synodontis is polyphyletic. These results are beneficial to a further understanding of the phylogenetic evolution of the Mochokidae family and Synodontis genus and provide a basis for species identification and conservation genetics.
