Pseudodendrothrips mori (Niwa, 1908) is major pest of mulberry, Morus alba L. We have determined a complete mitochondrial genome of P. mori of which length is 14,568 bp including 13 proteincoding genes, two ribosomal RNA genes, 22 transfer RNAs, and a single large non-coding region of 985 bp. The base composition was AT-biased (84.0\%). Structure and gene order of mitochondrial genome of P. mori (Niwa) were compared with mitochondrial genome of other Thysanopteran species. In addition, phylogenetic relationship among 10 complete or partial mitochondrial genomes of Thysanoptera were analyzed and discussed.
