Introduction

This genus was reviewed by Huang and Bourgoin (1993) who recognised eight species of which one, T. wilsoni Huang & Bourgoin, was recorded in Australia where it is distributed in NE New South Wales and SE Queensland. Since then, T. aschei Huang & Bourgoin, originally described from New Guinea, has been found in the Northern Territory. The species are unusual for the family Tropiduchidae in being dimorphic with a macropterous form with clear wings and a semibrachypterous form with dark coloured wings.

Diagnosis

A comphrehensive description was provided by Huang & Bourgoin (1993). The species are fairly easily identifiable by their small size (3–6 mm), brown colouration and paucity of crossveins in the tegmen which also has only three main longitudinal veins.
