Comparative mitogenomic analysis of Aposthonia borneensis and Aposthonia japonica (Embioptera: Oligotomidae) reveals divergent evolution of webspinners.

ABSTRACT: In this study, we report the complete mitochondrial genome (mitogenome, mtDNA) of Aposthonia borneensis and compare it with another sequenced webspinner, Aposthonia japonica. The A. borneensis mitogenome is smaller than A. japonica, but the size of each gene and the A + T content of protein-coding genes (PCGs) are almost identical in the two mitogenomes. Among the PCGs, atp6 shows the highest evolutionary rate and cox1 the lowest. The mtDNA map in A. borneensis is similar to Drosophila yakuba, but distinctly different from A. japonica, which has extensive rearrangement. Phylogenetic analyses dated the divergence time of the two webspinners at ca. 103 Ma. We speculate that the most recent common ancestor (MRCA) of A. borneensis and A. japonica was divided into several geographic groups duri
