TABLE 2. Raw pairwise distances (p-distances) between members of the Ctenotus labillardieri species group. Mean p-distances are given in parentheses; intraspecific distances are highlighted in grey. Note the low genetic divergence between Ctenotus catenifer and Ctenotus delli samples relative to congeners.
