The mitochondrial genome of the pentastome parasite Raillietiella orientalis Hett, 1915 (Raillietiellida; Raillietiellidae) with notes on its phylogenetic position.

In this study we sequenced and annotated the complete mitochondrial genome of the invasive reptile parasite Raillietiella orientalis using Illumina DNA sequencing. The length of the mitogenome was 15,320 bp and had a GC content of 33.1%. The mitogenome contained 13 protein-coding genes, two ribosomal RNA genes, and 22 tRNA genes, the order of which was diagnostic of Pancrustacean mitogenomes. A phylogenetic tree constructed from the 13 protein-coding genes of R. orientalis and 26 other Pancrustacean mitogenomes supported the placement of R. orientalis as part of the monophyletic subclass Pentastomida within the Maxillopoda and sister to the subclass Branchiura.
