• Oliarus hirsutus Löcker, B., Fletcher, M.J., Larivière, M.-C. & Gurr, G.M. 2006. The Australian Pentastirini (Hemiptera: Fulgoromorpha: Cixiidae). Zootaxa 1290: 1-138 [34].

  Type data:

   Holotype ANIC ♂ (coll: 15.iii.1961, K.D. Harley, light trap), Ingham, Queensland.

Introduction

This species was grouped by Löcker et.al. (2006) with O. hamatus Löcker and O. gracilis Löcker as the "gracilis group" on the basis of the following shared features: dark tubercles contrasting with brighter coloured veins; fork of Pcu+A1 distinctly basad of centre of clavus; aedeagus configuration, i.e., phallotheca with a long, slightly curved spine arising left lateral at apex, a smaller curved spine arising ventrally about midlength, and in one species a long slender spine arising dorsolaterally at apex; flagellum unarmed. As with other species in the group, O. hirsutus is tropical, being distributed across the top end of Western Australia, Northern Territory and Queensland, although it reaches as far south as Brisbane in SE Queensland.
