Type species Oliarus laertes Kirkaldy, 1906 . Etymology The genus is named after Australia , which is commonly called ‘Oz’. Gender: masculine. Morphology Body length: ♂ 4.1–7.7 mm , ♀ 5.0– 9.3 mm . Head: Vertex (total length) 1.2–2.3 times longer than wide; lateral carinae slightly to strongly elevated; subapical carina forking from lateral margin at 1/3–2/3 of total length of vertex; median carina 1/4–3/4 as long as median length of vertex. Position of maximum width of frons more or less around or distinctly distad centre of frontoclypeal suture; lateral carinae of frons convex (evenly rounded or rectilinear apically) or s­shaped. Anteclypeus with well­developed, evanescent or without median carina. Thorax: Forewing with fork ScRA+RP distad of fork CuA1+CuA2; r­m crossvein basad of fork MA+MP; RP apically bifid; MA apically trifid (rarely bifid); MP apically monofid, bifid or trifid; fork of Pcu+A1 distinctly basad or more or less around centre of clavus. Hind leg: tibia with 3–4 lateral spines; 6 large apical teeth; 1 st tarsomere with 7 (rarely 8) apical teeth and no platellae; 2 nd tarsomere with 7 (rarely 6) apical teeth and no platellae. Male genitalia: Genital styles without long, sclerotised, spinelike, dorsal process. Distribution Australia ( Australian Capital Territory, New South Wales, Northern Territory, Queensland, South Australia, Victoria, Western Australia ), Fiji , Rennell Island . Remarks Fennah recorded Ozoliarus laertes from Fiji ( Fennah 1950 ) and from Rennell Island ( Fennah 1970 ). This material has not been examined to confirm this distribution. Females (unless associated with males, see comments in Material & Methods section) could only be identified to genus level. The chaetotaxy of the hind legs varies slightly within species from the typical arrangement of 7 apical teeth on the 1 st and 2 nd tarsomere seen in this genus. In some specimens of Oz. quadratistylus 8 apical teeth were recorded on the 1 st tarsomere and some specimens of Oz. poculum , Oz. antennoides , and Oz. maru showed only 6 apical teeth on the 2 nd tarsomere. A well­developed median carina of the anteclypeus was recorded in all species, except for Oz. dedariensis (evanescent) and Oz. cynosurus (absent or evanescent median carina).
