Complete mitochondrial genome ofPseudocrangonyx joolaei(Crustacea: Amphipoda: Pseudocrangonyctidae)

초록

The complete mitochondrial genome of a subterranean pseudocrangonyctid amphipod,Pseudocrangonyx joolaei, was determined in this paper. The complete mitogenome ofP.joolaeiwas 14,814 bp in length with the typical 13 protein-coding genes, 22 transfer RNAs, two ribosomal RNAs, and a control region (CR). The gene order ofP.joolaeiwas unique in that the CR was an inversion, and the gene order ofPseudocrangonyxwas not concordant when compared to that ofP.daejeonensis, a subterranean amphipod found in Korea. A maximum-likelihood tree, constructed based on 26 eumalacostracan mitogenomes, confirmed thatP.joolaeisupported monophyly in the family Pseudocrangonyctidae and is most closely related to the superfamily Crangonyctoidea.
