The Tettigarctidae, known as the hairy cicadas, are a small relict (mostly extinct) family of primitive cicadas. Along with more than 20 extinct genera, Tettigarctidae contains a single extant genus, Tettigarcta, with two extant species, one from southern Australia (T. crinita) and one from the island of Tasmania (T. tomentosa). Numerous fossil species have been described from the Late Triassic onwards. Tettigarcta are the closest living relatives of the true cicadas. Genera Only one genus in the family Tettigarctidae is not extinct, Tettigarcta. Dates given in million years ago (Ma).
