Introduction

This genus was revised by Constant (2018) and now contains 12 species, all endemic to Australia. In addition, Olonia transversa (Walker) is listed here as a nomen dubium since its identity is unknown (Constant 2005). All species are restricted to parts of North or SE Queensland.

Diagnosis

The genus was created by Stål (1862) who simply included it in a key, written in Latin. The features used bt Stål to identify Olonia from other genera included in his key are: hind tibiae usually three spined; frons transverse, laterally angulate; thorax dorsally broad and short.

The genus was described in more detail by Constant (2018) and diagnosed as "Rather small-sized (6–12 mm), dark brown variegated with black and white, tegmina usually with a white marking along costal margin on nodal line and posterior wings usually with a white marking near externoapical angle, sometimes orange on disc. The genus can be recognized by the following set of characters: (1) gonostyli strongly sclerified and fused basally on about ⅓ of length; (2) gonostyli divided into a centroventral and a laterodorsal part; (3) gonostyli with laterodorsal part with large lateral process projecting laterally and bearing dorsoapical, articulate, spoon-shaped process; (4) aedeagus strongly reduced with dorsal portion of phallobase projecting dorsally as a spine or hook."
