Description of the first species of Scutigerella (Symphyla, Scutigerellidae) from China, with mitogenomic and genetic divergence analysis.

Scutigerellasinensis Jin & Bu, sp. nov. from China is described and illustrated. It is characterized by a deeply emarginated posterior margin of tergite 2, less differentiated marginal setae on all tergites, absence of seta a3 around the antennal base, and 6-8 setae on the first tergite. The complete mitochondrial genome of the new species is also analyzed and compared with the mitogenome of Scutigerellacauseyae . In the reconstructed Neighbor-Joining tree based on COI gene sequences, S.sinensis sp. nov. clusters with S.causeyae , however, with big distances. The genetic divergence among S.sinensis sp. nov. and congeners, species of Hanseniella and Scutigerella , and both families of Symphyla was analyzed using COI gene sequences.
