Etymology

The Greek term ‘olene’ means ‘elbow’. Named after a spine on the phallotheca which is bent like an elbow.

Colour

Body mid, dark brown or black, carinae paler; legs light to mid brown; forewing hyaline colourless with brown marks along crossveins, veins light brown, apically darker, tubercles dark brown (contrasting with veins), pterostigma light to mid brown; abdominal sternites dark brown.

Morphology

Body length: ♂ 4.4–5.1 mm, ♀ 5.2–6.6 mm.

Head: Vertex (total length) 1.6–2.0 times longer than wide; basal emargination obtusely angled or rectangular. Postclypeus with evanescent median carina. Rostrum reaching or not reaching hind coxae.

Thorax: Hind margin of pronotum obtusely angled or rectangular. Mesonotum with absent, evanescent or well­developed median carina, well­developed sublateral carinae and evanescent or well­developed lateral carinae. Forewing 3.3–4.0 times longer than wide; costa with 11–31 tubercles; 7–8 apical cells.

Male genitalia: Anal tube as in Figs 46F–H; ventromedian process of pygophore and genital styles as in Figs 46I–J. Aedeagus ( Figs 46K–M): Phallotheca with a short, almost straight spine (a); and a moderately curved spine (b) left lateral; a large strongly curved spine (c) with flattened, serrated processes; a very long, flattened spine (d); a very slender spine (e); a membranous spine (f); and a very short, dorsal spine (g). Flagellum partly sclerotised with 2–3 spines.

Remarks The material listed above as being excluded from the type series shows a minor variation from the type material. The phallotheca differs from the type in the absence of spine (e and g) and a rounded instead of a flattened spine (d) as in Figs 46N–P. Spine (f) is stronger in the variant than in the type. Further research is needed to clarify whether this variant represents a distinct species.
