Pleistocene Climate Oscillations and Geographic Barriers Shaped the Phylogeographic Structure of <i>Anaplecta omei</i> (Blattodea, Blattoidea, Anaplectidae) in Southern China: Evidence From Mitochondrial Genomes.

ABSTRACT: Anaplecta omei is the only species of Anaplecta widely distributed in southern China yet the processes shaping its genetic structure and range remain unclear. We used 97 complete mitochondrial genomes from 24 distinct geographic populations to characterize the genetic diversity, population structure, and evolutionary history of A. omei. Phylogenetic reconstruction, genetic diversity assessment, and population structure analysis revealed high haplotype diversity but low nucleotide diversity and a clear phylogeographic structure comprising four well-differentiated groups. Selection tests indicated no group-specific shifts in selective pressure, suggesting that physical barriers rather than adaptive divergence underlie this structure. Divergence-time estimates showed that
