It is a live-bearing species which in Tasmania is known only from a few localities. Like other members of the genus Pseudemoia , the strongly marked Glossy grass skink is not an easy species to identify. It gets its name from the shiny or glossy appearance of the skin. The species also has a distinct mid-lateral line bordered by black lines. The dorsal colour is light to dark olive green.
Frontoparietal shields are seperate.
The interparietal shield is almost as large as a frontoparietal. The midbody scales are in 25-28 rows, the dorsal scales, including paravertebral scales, with three distinct, rounded keels. The prefrontals are widely separated. The Glossy Grass skink is a small species. Males have a head and body length of 49 mm, and females reach 54-63 mm.
