Lissotes latidens, commonly known as the Wielangta stag beetle or broad-toothed stag beetle, is a species of stag beetle which is only found in an area centred in Wielangta Forest in eastern Tasmania.
The broad-toothed stag beetle has been recorded at less than 40 sites, scattered across an area of 280 square kilometres (110 sq mi), since it was first discovered in 1871.
It lives and breeds in moist decaying wood underneath logs on the ground.
Stag beetles are an ancient lineage thought to have evolved with the dinosaurs over 200 million years ago.
[2] It is threatened by bulldozing and burning, because this disturbs leaf litter and logs, removes old trees and dries out the forest by removal of the canopy.
