(Some Anisolabididae show a similar pattern.) The second tarsal segment extends under the first, but isn't wide as in the Forficulidae, and it has brush-like hairs underneath.
Native to many Pacific islands; introduced into Pacific Northwest, CA and FL (likely from Hawaii), and many areas worldwide, esp. tropical(1)(2)
