Phylogeography and genetic diversity of the widespread katydid Ducetia japonica (Thunberg, 1815) across China.

ABSTRACT: Habitat fragmentation can lower migration rates and genetic connectivity among remaining populations of native species. Ducetia japonica is one of the most widespread katydids in China, but little is known about its genetic structure and phylogeographic distribution. We combined the five-prime region of cytochrome c oxidase subunit I (COI-5P), 11 newly developed microsatellite loci coupled with an ecological niche model (ENM) to examine the genetic diversity and population structure of D. japonica in China and beyond to Laos and Singapore. Both Bayesian inference (BI) and haplotype network methods revealed six mitochondrial COI-5P lineages. The distribution of COI-5P haplotypes may not demonstrate significant phylogeographic structure (N _ST > G _S
