Here we present the complete mitochondrial genome of Tetraclita squamosa squamosa, which is 15,191 bp in length with 67.20% AT content. It contains 13 protein-coding genes, 2 ribosomal-RNA genes and 22 transfer-RNA genes. All PCGs except nad4l in T. squamosa squamosa start with ATN, and terminated with a complete stop codon, except nad3. Phylogenetic analysis based on mitochondrial PCGs shows that T. squamosa squamosa is clustered with T. serrata into a branch (BP ¼ 100). Our result is consistent with previous reports that genus Tetraclita and family Tetraclitidae are not monophyletic. This study contributes to further phylogenetic analysis within Cirripedia.

2019) The first mitochondrial genome of Megabalanustintinnabulum (Sessilia: Balanidae) from China: phylogeny within Cirripedia based on mitochondrial genes, Mitochondrial DNA Part B, 4:2, 4016-4018, ABSTRACTHere we present the complete mitochondrial genome of Megabalanus tintinnabulum. The genome is 15,107 bp in length with a 67.35% AT content. It contains 13 protein-coding genes (PCGs), 2 rRNAs genes, and 22 tRNAs. Both rRNAs are encoded on the light strand, as in the other crustacean and barnacle mitochondrial genomes. Besides five tRNAs are encoded on the light strand (nad1, trnV, trnL1, trnC, trnQ, and trnK). Only one PCG is encoded on the light strand (nad1), whereas the other 12 PCGs are located on the heavy strand, which is consistent with M. ajax. Phylogenetic analysis based on mitochondrial PCGs shows that M. tintinnabulum is clustered with M. ajax into a branch (BP ¼ 100), and the group with M. volcano with high support. This study contributes to further phylogenetic analysis within Cirripedia. ARTICLE HISTORY
