The mitochondrial genomes of five spring and groundwater amphipods of the family Crangonyctidae (Crustacea: Amphipoda) from eastern North America.

ABSTRACT: We sequenced the mitochondrial genomes of one spring-dwelling (Crangonyx forbesi) and four groundwater amphipods (Bactrurus brachycaudus, Stygobromus allegheniensis, S. pizzinii, and S. t. potomacus) from eastern North America using a shotgun sequencing approach on an Illumina HiSeq 4000 (Illumina, San Diego, CA). All five mitochondrial genomes encoded 13 protein-coding genes, 22 transfer RNAs (tRNAs), and two ribosomal RNAs (rRNAs) representative of subphylum Crustacea. Although the four groundwater species exhibited gene orders nearly identical to the ancestral pancrustacean gene order, the spring-dwelling species, C. forbesi, possessed a transposition of the trnH-nad4-nad4l loci downstream after nad6-cytb-trnS2. Moreover, a long nad5 locus, long
