The complete mitochondrial genome of the Japanese ghost shrimp Nihonotrypaea japonica (Crustacea, Decapoda, Axiidea).

We determined the complete mitochondrial (mt) genome sequence of the Japanese ghost shrimp Nihonotrypaea japonica (Ortmann 1891) (Crustacea, Decapoda, Axiidea). The N. japonica mt genome is first represented in infraorder Axiidea, which, together with infraorder Gebiidea, belonged to infraorder Thalassinidea until recently. The genome sequence of N. japonica is 15,274 bp in size, and the gene arrangement and transcriptional polarity are partially different from that of the Japanese mud shrimp, Upogebia major, which belongs to the infraorder Gebiidea. We present the mt genome of N. japonica, which could provide useful molecular information to construct a stable classification for infraorder Thalassinidea and to better understand the phylogenetic relationship of Thalassinidea with other decapod groups.
