Mitogenomics supports the monophyly of Mysidacea and Peracarida (Malacostraca)

Here, we provide the first complete mitochondrial genomes for two higher taxa of Peracarida, Lophogastrida and Stygiomysida. We examined Lophogaster typicus as a representative Spelaeomysis bottazzii Both mitogenomes have all typical metazoan genes (13 protein-coding genes, ribosomal RNA 22 transfer RNAs). The length 15,076 bp in L. 14,806 S. bottazzii. Gene order differs markedly from hypothetical pancrustacean/malacostracan ground pattern both species, typicus, were encoded on heavy strand. This is time this described crustacean. also reconstruct eumalacostracan phylogenies using data set consisting 98 species based alignments comprising protein-encoding well RNAs. find support monophyly Mysidacea three (Mysida, Lophogastrida, Stygiomysida). Moreover, our analyses monophyletic Peracarida with Amphipoda or + sister group to remaining Peracarida.
