Cicadoidea
! Tettigarctidae White! Ancestral morphology.
! Two extant species in the genus Tettigarcta White.
! Extant forms inhabit Southeastern Australia and
Tasmania.
! Cicadidae Latrielle! All remaining extant species.
Tettigarctidae
! Exhibit ancestral morphology, similar to fossils.
! Both sexes have a poorly developed timbal
apparatus and lack tympana.
! Males lack an acoustic resonating chamber in
the abdomen.
Tettigarcta crinita Distant
! Expanded pronotum
lacking paramedial
and lateral fissures
and a pronotal collar,
conceals much of the
mesonotum.
! Mesonotum lacks a
cruciform elevation.
