This earwig shows strong differences between the sexes, males reaching about 24.5 to 26.5 mm long with curved forceps of 10 to 11.5 mm, while females are smaller at about 15 to 17 mm long with shorter, straighter forceps of 5.5 to 7.5 mm.
It grips rough surfaces with claws on its feet and smooth surfaces with hairy pads on its legs, and like other earwigs it is active mainly at night, sheltering by day and using its pincers to handle prey and rival males rather than to defend itself against people.
