Complete mitochondrial genome of (Crustacea: Amphipoda: Pseudocrangonyctidae).

The complete mitochondrial genome of a subterranean pseudocrangonyctid amphipod, , was determined in this paper. The complete mitogenome of . was 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 of . was unique in that the CR was an inversion, and the gene order of was not concordant when compared to that of . , a subterranean amphipod found in Korea. A maximum-likelihood tree, constructed based on 26 eumalacostracan mitogenomes, confirmed that . supported monophyly in the family Pseudocrangonyctidae and is most closely related to the superfamily Crangonyctoidea.
