Prioninae
Tooth-necked and Aberrant Longhorn Beetles, prionids
Prioninae is a subfamily of long-horned beetles (Cerambycidae) comprising large, robust beetles typically measuring 25–70 mm. They are distinguished by males of several genera possessing enlarged mandibles used in male-male combat, analogous to stag beetles. Most species are nocturnal and attracted to light. Larvae are wood-borers, with the majority of documented species feeding on rotting wood or roots.
