• Oliarus lawlerorum Löcker, B., Fletcher, M.J., Larivière, M.-C. & Gurr, G.M. 2006. The Australian Pentastirini (Hemiptera: Fulgoromorpha: Cixiidae). Zootaxa 1290: 1-138 [26].

  Type data:

   Holotype MAGD 7413 ♂ (coll: 1.xi.1972, T. Weir, T. Angeles), 11 km S by W of Nimbuwah Rock, Cooper Creek, Northern Territory [12°17'S 133°20'E].

Introduction

O. lawlerorum is distributed across the northern tropics of Australia from the North Kimberley region in Western Australia to Cape York Peninsula in Queensland. It was grouped by Löcker et.al. (2006) with O. acanthopygophoris Löcker and O. cuberlii Löcker as the "acanthopygophoris group" on the basis of the following shared features: Forewing with 8 apical cells; genital styles with a large (rarely small) spinelike process directed dorsad; aedeagus with one ventral and one dorsal spine and a ventral sclerotised flap; flagellum very small and indistinct.

Diagnosis

Colour. Body dark brown, carinae and pronotum paler; legs light to mid brown; forewing hyaline colourless with indistinct brown marks along crossveins, veins light brown apically darker, tubercles slightly darker than veins, pterostigma light to mid brown; abdominal sternites mid to dark brown. Morphology Body length: ♂ 4.2–5.9 mm, ♀ 4.3–5.0 mm. Head: Vertex (total length) 2.0–2.9 times longer than wide; basal emargination acutely angled, rectangular or obtusely angled. Postclypeus with well-developed median carina. Rostrum not reaching hind coxae. Thorax: Hind margin of pronotum obtusely angled or rectangular. Mesonotum with well-developed median and lateral carinae and evanescent or well-developed sublateral carinae. Forewing 3.3–3.8 times longer than wide; costa without tubercles; 8 apical cells. Male genitalia: pygophore dorsolaterally on each side without long, outwardly curving, spinelike process as in O. acanthopygophoris, genital styles with large (sometimes small) spinelike process directed dorsad. Aedeagus: Phallotheca with a short, moderately curved spine ventrolaterally; a short, moderately curved spine dorsally; and a very reduced sclerotised flap ventrally. Flagellum membranous, unarmed, very small. (Löcker et.al. 2006)
