Dasia olivacea, the olive dasia or olive tree skink, is a semi- arboreal species of skink lizard native to Southeast Asia.
Distribution
Dasia olivacea is found south of approximately 15° north in Southeast Asia, including parts of Laos, Malaysia, Myanmar, Thailand, Singapore, Vietnam, throughout the island of Borneo ( Sarawak, Kalimantan, Brunei), the Indonesian islands of Bali, Java and Sumatra (among others), as well as India’s Andaman and Nicobar Islands.
The species is originally known from a single locality in Cambodia. The northernmost extreme for D. olivacea is possibly the Sakaerat Environmental Research Station in the Nakhon Ratchasima Province of eastern Thailand. [2]
Ecology and conservation
Dasia olivacea lives almost exclusively in trees, only rarely descending to nest or to move between trees. [1] Eggs may be laid more than once per year, in clutches of up to 14 eggs; incubation lasts 69 days. [1] Because it is very widespread and ecologically flexible, D. olivacea is considered to be a species of Least Concern on the IUCN Red List. [1]
Taxonomy
Dasia olivacea was first described by John Edward Gray, in a publication of the Annals of Natural History (1839), [1] [3] as the type species of the (then) newly-discovered genus Dasia. The type locality was "Prince of Wales Island" (now Penang Island). [1] [3]
Description
Mature individuals of Dasia olivacea have a green back, with bronze scales towards the flanks and 12 bands of ocelli (eye-like spots) reaching from side to side. [2] [3] The head is primarily a dark olive-green colour with black markings; the underside of the head is a bluish to yellowish green. [2]
