Prostomidae
Prostomidae is a family of beetles with no vernacular common name, though recent authors have coined the name jugular-horned beetles. They are often found in dead wood. The family consist of two genera with about 20 species. "Prostomis mandibularis" is known from North America. Other species of "Prostomis" are found in Africa, the Pacific region and East Asia. Species of "Dryocora" are known from New Zealand, Australia and Tasmania. Prostomidae are elongate beetles with parallel sided elytra. Thy are prognathous and have a large jugular process. The antennae are 11 segmented with a weak club formed by the  last three segments. The large mandibles, small eyes, the eltra and pronotum of the same width, and a tarsal formula of 4-4-4 make them distinctive. Larvae and adults are found mainly inside fallen logs. †"Vetuprostomis consimilis" is an extinct member described from mid-Cretaceous Burmese amber found in northern Myanmar.
