Pebble Bugs
Nogodinidae Melichar, 1898
Type genus: Nogodina Stål, 1859
(after biodiversity.org.au/afd/taxa/NOGODINIDAE): The Nogodinidae do not present a uniform appearance but are united through features of the male and female genitalia. The male has a massive phallobase with variform processes and distinctive style with long and narrow capitulum devoid of teeth. Within the females, most of the genera are characterised by elongate gonoplacs and narrow connective laminae of gonapophyses VIII and IX.
The Varciini are lacy-winged insects, the Tongini and the Bilbiliini have opaque tegmina and look like small Flatidae or even Issidae while the Lipocalliini are spherical with opaque tegmina which wrap around the body.
