Abstract

Here, we present the first mitochondrial genome of Eiconaxius baja. The mitogenome contains 13 protein-coding genes (PCGs), two rRNA genes, and 22 tRNA genes. The total length of the complete E. baja mitochondrial genome is 16,212 base pairs, and the GC content is 26.82%. The gene order is consistent with that of Eiconaxius serratus, and most other members of Axiidea. Phylogenetic analysis based on 13 PCGs places E. baja sister to E. serratus within Axiidae.

Keywords: Axiidae; Eiconaxius; mitogenome; phylogeny.
