Figure 2. Parsimony tree for samples of Cryptocercus from the eastern United States, based on DNA sequence of portions of the mitochondrial 12S and 16S rRNA genes and differential weighting of characters (see text for details). Tree length: 416.81, consistency index: 0.89, retention index: 0.92, rescaled consistency index 0.82; 772 characters had a weight of 1.0 and 109 characters had a weight < 1.0. Numbers above branches are bootstrap values (in %) and those below are decay indices (in steps). Bootstrap values below 50% and dacay indices of 0 are not shown. Numbers enclosed in circles are male diploid chromosome numbers as reported by Kambhampati et al. (1996). 1: Cryptocercus clevelandi,  2: Cryptocercus wrighti,  3: Cryptocercus punctulatus,
4: Cryptocercus garciai, 5: Cryptocercus darwini.
