Fig. 6
Diagnosis. Male. Head wider than long with vertex crest straight. Median clypeal carina not exceeding anterior imaginary line of eyes. Lateral margin of dorsal pronotal area not carinate. Mesoscutellar groove divided into two foveae by median carina. Metapostnotal median carina present, lateral carina incomplete. First median cell of forewing closed and oblong.
Description. Holotype (Fig. 6a). Male. Body length: 3.62 mm. Forewing length: 2.33 mm.
Color. Head black; mandible light castaneous, teeth yellow; antenna yellow. Mesosoma black, posterior margin of pronotum lighter; legs yellow, coxae and femora castaneous; tegula castaneous. Forewing hyaline tinged with pale castaneous; veins pale yellow; radical vein light castaneous; pterostigma light castaneous.
Pubescence. Body with white setae in different density. Antenna with dense appressed setae. Forewing with dense short light castaneous setae.
Head (Figs 6b, 6c, 6d). Head wider than long, LH 0.95 × WH. Mandible with four teeth and all with apex rounded. Median clypeal lobe subtriangular with apex nearly rounded; median clypeal carina not exceeding anterior imaginary line of eyes. Antennomeres II–V in ratio of 127:98:88:80: 84 in length and 2.15, 1.81, 1.40, 1.38, 1.29 × wide respectively; antennal scrobal carina absent. Frons coriaceous with shallow punctures separate at least 2.0 × its diameter. WF 1.24 × LE. LE 3.53 × DEV.Anterior ocellus passing supra-ocular line 2.13 × DAO; POL 1.29 × AOL; OOL 1.16 × WOT; DPV 0.37 × DAO. Vertex coriaceous with shallow punctures separate at least 2.0 × its diameter; vertex crest straight. Sides of head behind eyes rounded. Occipital carina absent. Malar line between mandible and eye present. Gena shiny with shallow sparse punctures separate at least 3.0 × its diameter.
Mesosoma (Figs 6e, 6f, 6g). Dorsal pronotal area coriaceous with tiny sparse punctures, about two-thirds of width; lateral margin not carinate, posterior margin almost straight; cervical pronotal area coriaceous; pronotal flange nearly invisible in dorsal view; lateral pronotal area coriaceous. Mesoscutum coriaceous with shallow punctures separate more than 1.5 × its diameter; parapsidal furrow straight and complete. Mesoscutellum coriaceous with shallow sparse punctures; mesoscutellar pit oval, mesoscutellar groove separated into two pit-like foveae by distinct median carina. Metapectal-propodeal disc wider than long, distinctly coriaceous; metapostnotum imbricate, with oblique rugulae laterally; basal triangular elevated area of metapostnotum present; metapostnotal median carina complete, metapostnotal lateral carina straight but incomplete, two-thirds of metapectal-propodeal disc, converging posteriorly; dorsal propodeal area imbricate, depressing laterally, lateral marginal carina of metapectal-propodeal complex complete, transverse posterior carina of metapectal-propodeal complex slightly incurved medially; propodeal declivity coriaceous; anterior metapleural area coriaceous, metapleural line with three pits; lateral surface of metapectal-propodeal complex coriaceous, upper one fourth with oblique rugulae. Propleuron coriaceous. Lateral surface of mesopectus coriaceous with shallow sparse punctures, slightly elevating around upper mesopleural fovea; mesopleural dentate process absent; upper mesopleural fovea and mesopleural pit developed; ventral surface of mesopectus coriaceous with punctures, mesodiscrimen present.
Forewing (Fig. 6h). First median cell oblong; Rs 2 v 1.70 × M 2 v; 2r-rs&Rs 2 v not arched apically.
Metasoma (Figs 6i, 6j, 6k). Abdominal terga shiny with sparse tiny punctures; longitudinal sulcus of second abdominal tergum extending to half of second abdominal tergum and fovea-like basally. Abdominal sterna shiny; second abdominal sternum with longitudinal carina but not complete; third abdominal sternum, and posterior area of fourth to sixth abdominal sterna with few punctures; posterior margin of fifth abdominal sternum with pair of tufted setae; posterior margin of hypopygium medially invaginated, with pair of median lobes, pair of lateral lobes very weak (Fig. 6i). Genitalia (Figs 6j, 6k): paramere broad with apex rounded, margin with long setae (Fig. 6k); digitus long with apex narrow, with long setae in ventral view (Fig. 6k); cuspis twisted and sparrow head-shaped, dorsal surface papillate (Fig. 6k); aedeagus bottle-shaped (Fig. 6j).
FEMALE unknown.
Type material. Holotype ♂ (ZJUH), China, Yunnan Province, Hekou, Nanxi Town, 22˚39ˊ24˝N, 103˚58ˊ8˝E, 7.vii.2003, Long Hu, No. 20048180. Paratype: 1♂ (ZJUH), China, Yunnan Province, Lushui, Shangjiang, 25˚42ˊ44˝N, 98˚48ˊ43˝E, 19.vii.2006, Bin Xiao, No. 200701115.
Distribution. China (Yunnan).
Etymology. The specific name “ latifrontalis ” is comprised of two Latin words: “ latus ” (wide) and “ frons ”. It refers to the wide frons of this species.
Comments. This species is similar to O. obtusus Xu & He, 2006 by vertex crest straight; metapostnotal lateral carina incomplete, first median cell of forewing oblong. However, O. latifrontalis sp. nov. can be distinguished by having metapostnotal lateral carina extending to two-thirds of metapectal-propodeal disc, WF 3.18 × WE and dorsal pronotal area not convex, whereas O. obtusus having metapostnotal lateral carina extending to four-fifths of metapectal-propodeal disc, WF 2.92 × WE and dorsal pronotal area convex.
