Pleioplectron Hutton, 1897 are small to medium cave weta found in forested and open habitats of North Island and South Island. The genus Weta is probably a synonym of Pleioplectron. Hutton (1899) moved P. diversum to Miotopus diversus, although Richards (1959) suggested a return to Pleioplectron. Unpublished genetic data and morphology suggest retention of Miotopus.
