First record of the complete mitochondrial genome and phylogenetic analysis of Limnodrilus hoffmeisteri Claparède, 1862 (Annelida; Clitellata; Oligochaeta)

The complete mitochondrial genome of Limnodrilus hoffmeisteri was analyzed using the Illumina NovaSeq 6000 platform. The length of the complete mitochondrial genome was 15,972 bp. The sequencing data, comprising 13 protein coding genes (PCGs), 2 rRNA genes, 22 tRNA genes, and a putative control region, were submitted to the National Center for Biotechnology Information (MW732144). A phylogenetic tree was constructed based on the sequences of 13 PCGs using the maximum likelihood method. To date, only a single study has been conducted on the complete mitochondrial genome of another aquatic oligochaete. This phylogenetic tree revealed that L. hoffmeisteri is clustered with Tubifex tubifex and forms a sister group to the earthworm group.
