Evolutionary relationships among asexual and sexual populations of Glyptotermes nakajimai. Phylogenetic trees were obtained by Bayesian analyses of mitochondrial COII (left) and nuclear ITS2 (right) sequences of G. nakajimai individuals representing each of the collection sites. The asexual lineage is highlighted in red, and the sexual lineage is highlighted in blue. Posterior probabilities (≥ 0.70) are shown at each node. The horizontal bar represents a distance of 0.1 substitutions per site. Multiple Glyptotermes spp. as well as Cryptotermes domesticus and Kalotermes flavicollis were used as outgroups. GenBank accession numbers are shown in parentheses. The topologies shown were very similar to those derived from maximum likelihood analyses, with some minor differences (see Additional file 2: Figure S2)
