Introduction

This genus of seven endemic Australian species is still awaiting revision. The species appear to be associated with Acacia (Fabaceae) and some are quite common.

 

Distribution

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 features used by Fletcher (2000 - see ID Keys below) are: lower margin of eye without knob-like process; frons of more or less uniform texture and colour throughout, not traversed by a furrow; antennae with second segment globular or barrel-shaped, no more than twice as long as broad, not or only slightly surpassing eyes and lateral angle of frons; first fork of vein Cu not closer to base of tegmen than to apex of clavus, basal or distal to first fork of vein M; tegmina parallel-sided or widened apically; first fork of vein M near base of tegmen, more or less level with first fork of vein R; lateral marginal angle of frons closer to apex of head than to frontoclypeal suture; first hind tarsomere with a ventral pad of densely packed setae.
