China , Yunnan, Lushui, Nima. Originally included specimens : Described from two males and two females. Name-bearing type : Holotype ♂: Yunnan, Lushui/ Nima, 2100m / Chinese Academy of Sciences [white label in Chinese, in black print except “Lushui/ Nima, 2100m ” handwritten in black ink]// 1981. V.29 / Collected by C.M. Chao [“1981. V.29 ” handwritten in black ink, remaining in black print, in Chinese]// HOLOTYPE [red label, in black print]// IOZ(E)216078 [blue label, in black print]// ♂ [white label, in black print]// Metopia / yunnanica / Zhao & Zhang [white label, in black print]// Metopia / yunnanica Chao et Zhang / Identified by C.M. Chao [“Identified by C.M. Chao” in black print, in Chinese, remaining handwritten in blue-black ink]. Holotype in good condition with terminalia in situ . Current identity : Metopia yunnanica Chao & Zhang, 1988 , as correctly listed by Pape (1996) and as treated by Xue & Chao (1998) . Additional type specimens : Allotype ♀: Yunnan, Yunlong, Mt. Zhibenshan, alt. 2500 m , 20.VI.1981 , Coll. by X.Z. Zhang. Paratypes 1♂ : Yunnan, Lushui, alt. 2100 m , 29.V.1981 , Coll. by C.M. Chao; 1♀: Yunnan, Dêqên, alt. 2500 m , 25.VIII.1981 , Coll. by X.Z. Zhang. All specimens in NZMC . Remarks : This species is related to M. suifenhoensis Fan , but can be distinguished from it by the frontal vitta being much wider anteriorly, subequal to the width of first antennal flagellomere; frontal bristle row without an interruption in the middle, entire parafacial covered with dense golden brown pollinosity (see also key in Kurahashi & Chaiwong, 2013 ). The male phallus has a uniquely swollen acrophallus ( Chao & Zhang, 1988a : fig. 13b). FIGURE 6. Metopia yunnanica Chao & Zhang, 1988 , male, holotype. A. Body, lateral view. B. Head, lateral view.

Ocellar bristles directed antero-laterally. Gena ground color black, with black bristles and light golden pollinosity, height 0.13– 0.17× eye height in lateral view ( Fig. 6 B). Antenna brown, almost reaching the level of vibrissal insertion, first flagellomere 3.5× as long as pedicel ( Fig. 6 C); arista short plumose; postocular bristles in six rows; vibrissa developed. Palpus yellow with black tip, slightly expanded in distal part. Thorax ground color black; scutum pollinosity goldenish gray with four black dorsal vittae. Chaetotaxy: acrostichals 0+0, dorsocentrals 2+3, intra-alars 0+2, supra-alars 2, postalars 2, postpronotals 2(3), notopleurals 2, scutellum with 1 apical, 1 marginal, 1 basal and 1 discal bristles. Pleuron with meropleurals 3, katepisternal bristles 1: 1, prosternum, metasternum, proepimeron and proepisternum bare. Wing hyaline; subcostal sclerite and basicosta yellow, bare; tegula black; costal spine not differentiated ( Fig. 6 A); vein R1 bare, vein R4+5 setose dorsally from junction of R2+3 halfway to crossvein r-m; lower calypter yellow.
