Trilobite beetle, Platerodrilus foliaceus Masek & Bocak, 2014 of south Sarawak / Borneo

Platerodrilus is a genus of beetles from the Lycidae family. In the scientific literature they are often referred to as Duliticola, which is an outdated, more recent synonym. The females retain a larval form as adults and are about 50mm long. The females and larvae have a flattened, dark body with large scales over the head resembling trilobites, therefore the informal common names are trilobite beetle.
