Genus Oteana Hoch

Oteana Hoch, 2006: 3 .

Type species Oliarus euphranor Fennah, 1958: 131 , by original designation.

Morphology

Body length: ♂ 6.2–7.7 mm, ♀ 7.2–10.1 mm.

Head: Vertex (total length) 1.4–2.0 times longer than wide; lateral carinae slightly to moderately elevated; subapical carina forking from lateral margin at 1/3–1/2 (in Ot. sponsa 1/3–1) total length of vertex; median carina 1/2–3/4 as long as median length of vertex. Position of maximum width of frons more or less around centre of frontoclypeal suture; lateral carinae of frons convex (evenly rounded or rectilinear apically) or s­shaped. Anteclypeus with well­developed 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; MP apically bifid; fork of Pcu+A1 distinctly basad of (sometimes more or less around Ot. lubra and Ot. sponsa ) centre of clavus. Hind leg: tibia with 3 lateral spines; 6 large apical teeth; 1 st tarsomere with 7 apical teeth and no platellae; 2 nd tarsomere with 5 apical teeth and no platellae.

Male genitalia: Genital styles without long, sclerotised, spinelike, dorsal process.

Distribution

Australia (New South Wales, Northern Territory, Queensland, South Australia, Victoria, Western Australia) , Fiji, New Caledonia, Society Islands , Cook Islands.

Remarks

Fennah recorded Oteana lubra from Fiji ( Fennah 1950) and New Caledonia ( Fennah 1969). 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. The body length measurement given above is derived from females assigned to species level plus additional females which could only be identified to genus.

Oteana differs from all other Australian pentastirine genera in the unique combination of the following features: 2 lateral spines on the hind tibia, 7 apical teeth on the 1 st hind tarsomere and 5 apical teeth on the 2 nd hind tarsomere.

Twelve species of Oteana are recorded from the Society Islands and one species from the Cook Islands ( Hoch 2006), none of which is conspecific with the Australian species. The arrangement of spines on the phallotheca of the Polynesian species shows some similarities to species of the lubra group. In general, they can be differentiated from the Australian species by the presence of a sclerotised distal spine on the flagellum (the flagellum of Australian species is unarmed). The body length of species of Oteana from the Cook and Society Islands (males 4.9–8.0 mm, females 5.5–9.0 mm) is also similar to that of the Australian species.
