We report the complete mitochondrial genome of the hybrid flounder
Platichthys stellatus
(♀)
Platichthys bicoloratus
(♂). The mitochondrial genome contained
13
protein-coding genes, 2 ribosomal RNA (rRNA) genes,
22
transfer RNA (tRNA) genes, and 1 control region (D-loop), for a total length of 16,874 bp. The nucleotide composition of the heavy strand was 29.15% C, 26.99% A, 26.14% T, and 17.71% G. A maximum-likelihood phylogenetic analysis showed that the hybrid flat fish was a member of the same clade as
P. stellatus
(maternal inheritance). Our findings add to the extant data on the subfamily Pleuronecidae and provide insight into their molecular phylogeny and taxonomy.
