The complete mitochondrial genome of squat lobster, Munida gregaria (Anomura, Galatheoidea, Munididae)

Abstract

We determined the mitogenome sequence of Munida gregaria (Fabricius, 1793) (Anomura, Galatheoidea, Munididae), which is the first complete mitogenome sequence in the family Munididae Ahyong, Baba, Macpherson, Poore, 2010. The mitogenome of M. gregaria is 16,326 bp and contains 13 protein-coding genes (PCGs), 22 transfer RNAs (tRNAs), two ribosomal RNAs (rRNAs), and two control regions (CRs). Mitogenome analysis of M. gregaria showed an extra copy of the CR and rearrangements of two PCGs (nad2 and nad3) compared to the arthropod ground pattern. Additionally, it contains a tRNA (trnY) inversion and rearrangements of two PCGs (nad1 and nad3) when compared with that of Neopetrolisthes maculatus and Shinkaia crosnieri, respectively. The phylogenetic tree confirmed that M. gregaria belongs to the superfamily Galatheoidea within Anomura. Our results will be useful for the detailed study of mitogenome evolution and the phylogenetic relationships among the superfamily in the infraorder Anomura
