    Abstract:
    Capitulum mitella (Crustacea: Cirripedia) is an important stalked barnacle. The first mitochondrial genome of C. mitella from China was presented, which is a circular molecule of 15,930 bp in length and AT content is 64.4%. It encodes 37 genes, including 13 PCGs, 22 tRNAs, and two rRNAs, which is consistent with most barnacles species reported. There are 15 genes encoded on the light strand and 22 genes encoded on the heavy strand. Identical to most barnacles species reported, srRNA and lrRNA genes are adjacent and separated only by trnV gene. Phylogenetic trees showed that C. mitella clustered with Pollicipes polymerus, indicating Pollicipedidae is monophyletic. However, Scalpelliformes was not monophyletic from the phylogenetic tree. From the level of order, the Lepadiformes was located at the base of the phylogenetic tree, indicating that its divergence time was earlier than Scalpelliformes. The results provided more insights into phylogenetic consideration at the genomic level within superorder Thoracica.
