Platerodrilus
Platerodrilus is a genus of beetles of the family Lycidae. They commonly appear in the literature under the name "Duliticola", which is an obsolete junior synonym. The females retain a larval form as adults (larviform females) and are about 40–80 mm in length. The females and larvae have a flattened, dark body with large scales over the head, resembling trilobites, hence the informal names trilobite beetle, trilobite larva or Sumatran trilobite larva. In contrast, the males are much smaller, 8–9 mm, resembling other beetles. Species are found in tropical rainforests of India and South-east Asia.
