Insulanoplectron is a genus of cave wētā in the family Rhaphidophoridae, with just two species: the Snares Island Wētā and the Tin tokoriro from Rakiura. Insulanoplectron spinosum is endemic to the subantartic Snares Island where it is considered to be naturally uncommon. Insulanoplectron stanneum is known from a single disused mineshaft on Rakiura/Stewart Island, New Zealand. Rhaphidophoridae are nocturnal crickets often found in caves, all around the world. During the day on the Snares, wētā can be found hiding in seabird burrows.
