Popis:	The genera Teredorus and Systolederus belong to Tetriginae and Metrodorinae respectively. However, species within these two genera have strikingly similar features, made it difficult to identify clearly by morphological characteristics. In this study, we sequenced the mitochondrial genomes (mitogenomes) of two Teredorus species, and compared them with Systolederus mitochondrial sequences. The sequenced mitogenomes of T. hainanensis and T. bashanensis are 14,946 bp and 14,775 bp in size, respectively. The A+T content of mitogenomes is 76.2% (T. hainanensis) and 74.0% (T. bashanensis). Comparative analysis showed that mitochondrial sequences and structure were similar within these two genera. The results of K2P distances and phylogenetic analysis revealed that Systolederus and Teredorus might be likely considered as one genus of Teredorus. It will provide important resources for further understanding of the taxonomy and phylogenetic relationship of Systolederus and Teredorus.
