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.[1][2]
Genera
Only one genus in the family Tettigarctidae is not extinct, Tettigarcta.[3][4]
Many fossil genera have been historically attributed to this family. However, it has been argued that Tettigarctidae including all of these fossil species is a
paraphyletic group that also includes some cicadas that are more closely related to
Cicadidae than to Tettigarcta.[5]
Dates given in million years ago (Ma).
