The complete mitochondrial genome of (Malacostraca: Decapoda: Hymenoceridae).

In this study, the complete mitochondrial genome sequence of the is reported for the first time. The length of genome is 15,786 bp, including 13 protein-coding genes, two ribosomal RNA genes, and 21 transfer RNA genes. Nucleotide composition of the whole mitogenome was 37.26% A, 28.42% T, 21.92% C, and 12.40% G. The AT and GC skewness of mitogenome sequence was 0.135 and 0.277, respectively. The reconstructed phylogenetic relationships of 22 Decapoda species based on 13 protein-coding genes were highly supported and the clade of all Palaemonoidea shrimps included had a high support value. Our results shall provide a better understanding in the evolutionary histories of the Decapoda.
