Fig. 10
Diagnosis. Female. Head wider than long, vertex crest distinctly incurved. Frons with dense punctures. Median clypeal carina reaching anterior imaginary line of eyes. Dorsal pronotal area distinctly coriaceous and papillate. Lateral margin of dorsal pronotal area carinate and papillate. Basal one third of mesoscutum weakly coriaceous and elevated. Mesopleural dentate process developed. Metapostnotal median and lateral carina present. First median cell of forewing closed.
Description. Holotype (Fig. 10a). Female. Body length: 5.86 mm. Forewing length: 3.71 mm.
Color. Head black; mandible castaneous, teeth lighter; antenna dark castaneous, antennomeres I-II lighter. Mesosoma black; legs castaneous, coxae and femora darker; tegula castaneous. Metasoma dark castaneous with posterior margin of each segment lighter. Forewing hyaline tinged with light castaneous; veins and prestigma yellowish; pterostigma castaneous.
Pubescence. Body with white setae in different density. Antenna with dense appressed setae. Forewing with dense short light castaneous setae.
Head (Figs 10b, 10c, 10d). Head wider than long, LH 0.86 × WH. Mandible with four teeth; upper two smaller with apex rounded; lower two triangular. Median clypeal lobe subtriangular with apex slightly rounded; Median clypeal carina reaching anterior imaginary line of eyes. Antennomeres II–VI in ratio of 178:194:160:157: 170 in length and 1.91, 1.81, 1.36, 1.28, 1.60 × wide respectively; antennal scrobal carina present. Frons coriaceous with dense punctures separate at most 1.50 × its diameter. WF 1.44 × LE. LE 1.81 × DEV. Anterior ocellus passing supra-ocular line 1.67 × DAO; POL 1.08 × AOL; OOL 1.49 × WOT; DPV 1.5 × DAO. Vertex coriaceous with dense punctures separate at most 1.50 × its diameter; vertex crest incurved. Sides of head behind eyes slightly converging. Occipital carina absent. Malar line between mandible and eye present. Gena shiny with sparse punctures; ventral area of gena coriaceous, with dense punctures separate at most 2.0 × its diameter.
Mesosoma (Figs 10e, 10f, 10g). Dorsal pronotal area coriaceous and papillate, almost half as long as wide; lateral margin carinate, posterior margin straight; cervical pronotal area coriaceous and papillate; pronotal flange visible in dorsal view; lateral pronotal area coriaceous. Mesoscutum coriaceous with punctures separate by 0.5–2.0 × its diameter; basal one third weakly coriaceous, slightly elevated; parapsidal furrow extending to two-thirds of mesoscutum. Mesoscutellum shiny weakly coriaceous with sparse punctures; mesoscutellar pit oval, mesoscutellar groove with several weak longitudinal carinae. Metapectal-propodeal disc wider than long; metapostnotum with irregular rugulae, median carina complete, lateral carina complete and straight, converging posteriorly; basal triangular elevated area of metapostnotum absent; dorsal propodeal area coriaceous, upper one third with short oblique rugulae; lateral marginal carina of metapectal-propodeal complex complete, transverse posterior carina of metapectal-propodeal complex trapezoidal, incurved posteriorly; dorsal propodeal area imbricate with short irregular rugulae near transverse posterior carina, depressing laterally; propodeal declivity coriaceous; Lateral surface of metapectal-propodeal complex coriaceous, upper one third with short oblique rugulae. Propleuron coriaceous. Lateral surface of mesopectus coriaceous with dense large punctures; dentate process developed, upper mesopleural fovea and mesopleural pit developed; posterolateral area shiny; ventral surface of mesopectus coriaceous, weakly papillate; subpleural signum carinate, mesodiscrimen present.
Forewing (Fig. 10h). First median cell closed; Rs 2 v 2.09 × M 2 v; 2r-rs&Rs 2 v slightly arched apically.
Metasoma. Abdominal terga shiny with sparse tiny punctures; longitudinal sulcus of second abdominal tergum present extending to more than half of second abdominal tergum and fovea-like basally. Abdominal sterna shiny; second abdominal sternum with longitudinal carina; apical half of third abdominal sternum, fifth abdominal sternum papillate; third to sixth abdominal sterna with sparse punctures apically.
MALE unknown.
Variation. Body length: 5.74–5.86 mm; forewing length: 3.69–3.71 mm.
Type material. Holotype ♀ (ZJUH), China, Yunnan Province, Kaiyuan, Nanhe, 39˚49ˊ17˝N, 115˚53ˊ19˝E, 13.vii.2003, Long Hu, No. 20048185. Paratype, 1♀ (ZJUH), China, Yunnan Province, Gaoligong Mountain, 25˚59ˊ17˝N, 98˚49ˊ26˝E, 20–21.vii.2006, Jie Zeng, No. 200701078.
Distribution. China (Yunnan).
Etymology. This species is named after the type-locality.
Comments. This species is similar to O. ovatus Xu & He, 2006 by forewing with first median cell closed; posterior margin of head incurved and frons with dense punctures. However, O. yunnanensis sp. nov. can be distinguished by having metapostnotal lateral carina straight and width of first median cell of forewing less than 1.0 × M 2 v, whereas O. ovatus having metapostnotal lateral carina curved and width of first median cell of forewing at least 3.0 × M 2 v.
