摘要

The complete mitogenome of the common Chinese whip scorpion, Typopeltis sinensis (Butler, 1872) was sequenced and compared with another Uropygid mitogenome of Mastigoproctus giganteus (Lucas, 1835). Structural divergences include the absence of one tRNA-Leu and strand inversions in four protein coding genes (PCGs). All PCGs showed Ka/Ks ratios <1, which indicates purifying selection, with COI (0.04) evolving the most conservatively and ATP8 (0.65) accumulating the highest nonsynonymous substitutions. Phylogenetic reconstruction based on 602-bp COI sequences from seven species indicates that T. sinensis is most closely related to T. stimpsonii.
