Body length. Male. 7.6 – 8.0 mm (+/ 0.2); n= 3. Female. 9.0 mm; n= 1.
Anterior part of vertex and areolets dark brown, posterior corners of vertex stramineous. Frons irregularly testaceous, darkest just above frontoclypeal suture. Postclypeus yellowish, anteclypeus dark brown. Carinae of head yellowish. Pronotum with discoidal and ventral areas dark brown, carinae stramineous. Tegulae stramineous. Mesonotum dark brown with distinct longitudinal stripes: all longitudinal carinae yellowish, area enclosed by lateral carinae on each side testaceous, posterior tip of mesonotum stramineous. Body generally dark brown, legs light brown. Tegmina and wings hyaline, translucent, without conspicuous pattern. Costal vein and pterostigma light brown. Venation of tegmina generally yellowishbrown, Yvein, veins enclosing apical cells and costal vein at junction of Yvein and costal vein slightly darker.
Proportions and carination of head and thorax as well as spinulation of hind legs as described for the genus.
Male genital complex (figs 79–84)
Genital segment (figs 79, 80) bilaterally asymmetrical, dorsal apical angle of subrectangular lobe on left side more strongly pronounced than on right side (fig. 80, arrow). Subrectangular lobes in lateral aspect slender, gradually tapering. Anal segment (figs 81, 82) bilaterally symmetrical, broadly ovate. Parameres (fig. 83) distally produced into a pointed tip. Aedeagus (fig. 84): shaft ventrally with 3 spines (a 1 –a 3) and a weakly developed longitudinal ridge (a 4?): right lateral spine (a 1) compressed, strongly developed, hookshaped, directed laterad to the right side. Median spines (a 2, a 3) short, stout, toothlike, directed straight ventrad and laterad to the left side, respectively. Apical spine of shaft (a 5) long, slender, terete, in repose curved laterobasad to left side; subapical spine (a 6) strongly developed, taeniform, curved laterad to the left side. Flagellum long, in repose reaching base of shaft, distally bispinose.
Female genitalia as described for the genus.
Named for the type locality, Temehani Plateau, on Raiatea.
Endemic to Raiatea.
O. temehani ressembles O. omai from Huahine in external and genital characters; it is distinguished from this species in small, but consistent differences pertaining to the male genital structures, especially the shape of the genital segment (subrectangular process gradually tapering towards apical angle vs. short and stout in O. omai ) and the aedeagus (e.g., flagellum distinctly longer than in O. omai ).
