• Oliarus gracilis Löcker, B., Fletcher, M.J., Larivière, M.-C. & Gurr, G.M. 2006. The Australian Pentastirini (Hemiptera: Fulgoromorpha: Cixiidae). Zootaxa 1290: 1-138 [30].

  Type data:

   Holotype QM T123830 ♂ (coll: at light, 2.–5.xii.1986, K. Houston, K. Sadler; originally from QDPI), Horn Island, Queensland [10°37'S 142°17'E].

Introduction

This species was grouped by Löcker et.al. (2006) with O. hamatus Löcker and O. hirsutus 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. It is based on a single male specimen from Horn Island, Torres Strait and a series of males and females from West Claudie River, Cape York Peninsula, North Queensland.
