Lygosoma veunsaiense is a species of skink that is endemic to northeastern Cambodia. Its description as a new species was published in 2012, receiving both local and international publicity.
In 2010, at the remote rainforest area of Veun Sai-Siem Pang National Park in Ratanakiri Province, Cambodia a Fauna and Flora International herpetologist, Thy Neang, first discovered Lygosoma veunsaiense. Peter Geissler from Museum Koenig in Germany, was one of the authors who described the skink.
This type of lizard has iridescent rainbow skin with a long tail and short legs. The outer ear opening is absent; supranasals distinct and separated from each other by frontonasal; supranasals not fused with nasals; midbody scales in 22 rows; fontoparietals paired; five supralabial scales; a light stripe present on outer edge of the dorsum; and a dark dorsolateral stripe present, from behind the eye to the tail.
Lygosoma veunsaiense spends most of its life underground in the rainforest.
