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.[1] The females stay in the larval form and are about 40–80 mm in length. They have a flat dark body with large scales over the head, resembling trilobites, hence the informal names Trilobite beetle, Trilobite larva or "Sumatran Trilobite larva". The males are much smaller, 8–9 mm, with a beetle-like appearance. Most are found in tropical rainforests, notably in India and South-east Asia.
