This is a small, mainly tropical family with Chelisochinae represented in northern Australia by dark brown to black earwigs ranging from 15-25 mm long. They are commonly encountered among the tightly overlapping leaf bases of Pandanus where they are afforded protection during the day.


Hamaxas is small, and has pubescent legs with tibiae smooth above. Chelisoches is larger, robust and the tibiae are flattened and sulcate above. C. morio is synanthropic and widely distributed throughout the Pacific and elsewhere. Proreus is similar to Chelisoches , but more slender, and has slender antennae; Lamprophorella has a strongly depressed body.
