Conservation
IUCN Red List status is Least Concern, as it has a wide distribution and tolerates habitat modification well.
Physical Description
Brownish or grayish body with a lighter central dorsal stripe bordered by small, dark spots or dashes. The head is relatively distinct from the neck, displaying dark markings on the temporal region and near the back of the head. Scales are typically keeled.
Size & Dimensions
