Vanderschoors Stag Beetle (Hoplogonus vanderschoori) is a flightless, glossy black, ground-dwelling beetle reaching up to 30 mm in total length. Stag beetles have enlarged mandibles (or jaws) which, in their resemblance to the antlers of a male deer (or stag), give these beetles their name. Vanderschoors Stag Beetle is found only in a small areas of native forest in north-eastern Tasmania west and south of Pyengana. The species is found in leaf litter and under logs in wet eucalypt forest, damp forest, mixed forest and rainforest. It has also been found in damp and wet gullies within dry forest. A deep layer of accumulated leaf litter is vital to the survival of this Vanderschoors Stag Beetle. The main threat is any activity resulting in exposure and drying of the soil and leaf litter. This includes activities that open up the forest canopy or disturb the forest floor, such as cutting or clearing live or dead vegetation, and burning.
