Characters distinguishing V. bitatawa from close relatives. Ranges for snout–vent and tail length of V. olivaceus represent our data combined with Auffenberg (1988; 90 specimens) and D. Bennett (2009, unpublished; 28 specimens); dashes, missing data. See electronic supplementary material for definitions and discussion.
