First report on the complete mitochondrial genome of the deep-water scalpellid barnacle (Cirripedia, Thoracica, Scalpellidae).

Scalpellids are one of the largest families of Scalpelliformes and reproduce either androdioeciously or dioeciously. Here, we characterized the first mitogenome of a scalpellid barnacle (), which was 15,593 bp in length with a 71.5% AT content. In comparison with the pollicipedids and , the tRNA genes of . were rearranged between ND3 and ND5, between CYTB and ND1, and between 12S rRNA and ND2. On the mitogenomic tree, the Scalpelliformes families Pollicipedidae and Scalpellidae were not monophyletic, which concurs with previous studies.
