Fig. 5
Chronogram showing divergence times among Kalotermitidae, including the asexual and sexual lineages of Glyptotermes nakajimai. The tree was inferred based on an alignment of mitochondrial COII sequences, using the program BEAST v1.8.2. The asexual lineage is highlighted in red, and the sexual lineage is highlighted in blue. Branch lengths are drawn to a time scale given in millions of years. Bars represent 95% confidence intervals for estimates of node times. Four fossil termites provided minimum age constraints for calibration of the molecular clock at the nodes denoted by asterisks (see “Methods” for further details concerning these fossils)
