( Figs 2 View FIGURES 1 – 12 , 16–25 View FIGURES 13 – 23 View FIGURES 24 – 34 )
Description. Body length (from apex of vertex to tip of forewings): male 4.4–5.4 mm (N=6), female 5.2–5.7 mm (N=4).
General colour brown to pitchy, abdomen dark brown. Vertex, pronotum and mesonotum pale yellow to brown ( Figs 10–12 View FIGURES 1 – 12 ). Frons with two pairs of dark markings: one pair round in upper part; other pair oval near postclypeal suture, medially almost fused, looking like one circular patch; all forming obvious three dark patches. Postclypeus dark brown, anteclypeus stramineous with pale yellow median callus, genae pale yellow, lorae diffusely dark brownish ( Fig. 11 View FIGURES 1 – 12 ). Forewings transparent, tips of spines on hind tibiae and tarsi black ( Fig. 10 View FIGURES 1 – 12 ).
Vertex ( Fig. 45 View FIGURES 45 – 55 ) shorter in middle than widest breadth (1:1.3). Frons ( Fig. 47 View FIGURES 45 – 55 ) longer in middle than widest breadth (1.7:1.0). Pronotum ( Fig. 45 View FIGURES 45 – 55 ) broader than long (4.1:1.0). Froewings ( Fig. 48 View FIGURES 45 – 55 ) form about seven apical cells. Hind tibia with 2 distinct lateral spines, spinal formula of hind leg 7–7–2.
Male genitalia. Pygofer ( Fig. 50 View FIGURES 45 – 55 ) symmetrical, high and narrow, anterior margin and posterior margin paralleled. Anal tube ( Figs 50, 53 View FIGURES 45 – 55 ) short, anal style not surpassing anal tube. Gonostyli ( Figs 50–52 View FIGURES 45 – 55 ) bilaterally symmetrical, in lateral view about 1.7 times as long as broad, sickle-like, apical 1/3 broad, middle concave, apex with strong hook-like process arising from laterodorsal margin, acute tip bent lateroventrad, with triangular process arising from base of dorsal margin, apical part with a tooth-like process arises from the inner dorsal margin in side view. Aedeagus ( Figs 50, 54–55 View FIGURES 45 – 55 ) elongate and tubular; shaft slender in lateral view, base very broad, then becoming narrow, tip nozzle-shaped, phallotrema apically exposed. Periandrium ( Figs 50, 54–55 View FIGURES 45 – 55 ) surrounding penis at base, dorsally connected with ventrobasal margin of anal tube, ventral projection well developed, with asymmetrical lobate process, subapical part with one tooth-like process pointed to outer side in left view, ventral margin with 2 teeth.
Type Material. Holotype ♂, Lanping (26°30′N, 99°16′E), Yunnan, China, 12 Aug. 2000, X.-S. Chen. Paratypes: 2♂♂, 1♀, same data as holotype; 4♂♂, 4♀♀, Lanping, Yunnan, 5 Aug. 2012, J.-K. Long and Y.-G. Xiao.
Host plant. Unknown.
Distribution. China (Yunnan).
Etymology. The specific name is a combination of the Latin words “ tri ” (three) and “ maculatus ” (marking), meaning that its frons with three dark brown markings.
Remarks. This species is similar to O. fuscus sp. nov., but can be distinguished from the latter by the frons with two pairs of dark markings: one pair round in upper part; other pair oval near postclypeal suture, looking like one circular patch; all forming obvious three dark patches; gonostyli sickle-like, apical 1/3 broad, middle part concave, apical part with strong hook-like process arising from laterodorsal margin in side view; subapical part of periandrium with one tooth-like process pointed to outer side in left view.
