Complete mitochondrial genome of Kishi velvet shrimp, Metapenaeopsis dalei (Rathbun, 1902) (Crustacea: Decapoda: Penaeidae) in the East China Sea.

We determined the complete mitochondrial genome of Metapenaeopsis dalei (Rathbun, 1902), which is collected from East China Sea (124°E and 33.5°N). Total mitochondrial genome length of M. dalei was 15 939 bp, in which 13 proteins, two ribosomal RNAs, 22 transfer RNAs and a putative control region were encoded. The gene arrangement of M. dalei was well conserved with nine known Penaeidae mitochondrial genomes from COX1 to tRNATyr . The protein-coding genes started with ATN except for COX1 in which ACG is used. Four genes (COX2, COX3, ND3 and ND5) exhibited an incomplete stop codon. Nucleotide sequence identity of M. dalei mitochondrial genome to those of nine Penaeidae species ranged from 78% to 80%. Based on the COI region, M. dalei is most closely related to Penaeus notialis.
