Wohlfahrtia hirtiparafacialis Chao & Zhang in Zhang & Chao, 1996a: 215. China, Qinghai, Hoh Xil, Gangqiqu.

Originally included specimens: Described from four males and four females.

Name-bearing type: Holotype ♂: Qinghai, Hoh Xil/ Gangqiqu, 5100m / Chinese Academy of Sciences [white label in Chinese, in black print except “Hoh Xil/ Gangqiqu, 5100m ” in handwritten]// 1990. VI.25 / Collected by X.Z. Zhang [“1990. VI.25 ” handwritten in black ink, remaining in black print, in Chinese]// HOLOTYPE [red label, in black print]// IOZ(E)1218598 [white label, in black print]// Wohlfahrtia / hirtiparafacialis / Chao et Zhang/ Identified by C.M. Chao [“Identified by C.M. Chao” in black print, in Chinese, remaining handwritten in blueblack ink].

Holotype in fair condition and terminalia extracted and fully visible.

Current identity: Wohlfahrtia magnifica ( Schiner, 1862) , as treated by Verves (1985) and here proposed as a senior synonym of Wohlfahrtia hirtiparafacialis Chao & Zhang, 1996 , syn. n.

Additional specimens: Wohlfahrtia hirtiparafacialis Chao & Zhang : Allotype ♀: China: Qinghai, Hoh Xil, Xijir Ulan Lake, alt. 4800m, 12.VII.1990, Coll. by X.Z. Zhang. Paratypes 1♀: China: Qinghai, Hoh Xil, Sangqia, alt. 4700m, 16.VI.1990; 2♂♂, 2♀♀: China: Qinghai, Hoh Xil, Gangqiqu, alt. 4800m, 7–12.VII.1990; 1♂: China: Qinghai, Hoh Xil Lake, alt. 4850m, 30.VII.1990; Coll. by X.Z. Zhang ( NZMC). Wohlfahrtia magnifica (Schiner) : 1♂: Hungary: Nat. park Kiskunsάg, 23.VIII.1986 ( ZMUC); 10♂♂, 6♀♀: China: Xinjiang, Changji, Jimsar, 44°07′25.68′′N, 88°27′33.98′′E, alt. 500m, 25.VI.2014, Coll. by M. Zhang ( MBFU).

Remarks: Chao & Zhang (1996a) compared their new species only with W. stackelbergi Rohdendorf , which has very different male terminalia and in particular has a rather short, blunt, almost straight cercus, and the tip of the distiphallus is bent ventrally at a more or less right angle. We consider the similarities with the male terminalia of W. magnifica as a sufficiently good match to consider the two nominal taxa as conspecific.

Redescription of Male: Body length 8.0–11.0 mm ( Fig. 22 A). Eye bare, red. Fronto-orbital plate, parafacial and postocular strip black with silvery gray pollinosity; fronto-orbital with several black bristles in upper part, parafacial with several black bristles in lower part, about 2.1× as broad as fronto-orbital plate. Frontal vitta 1.3– 1.6× as broad as fronto-orbital plate at the narrowest point; frons at vertex 0.25–0.32× head width ( Fig. 22 C); frontal row of 7 or 8 bristles; outer vertical bristle differentiated from postocular bristles. Ocellar bristles directed antero-laterlly. Gena ground color black, with dense and long black bristles and gray pollinosity, height about 0.3× eye height in lateral view ( Fig. 22 E). Antenna grayish brown, not reaching the level of vibrissal insertion, first flagellomere 2.0× as long as pedicel ( Fig. 22 C); arista micropubescent, basal half swollen. Palpus yellow, expanded in apex ( Fig. 22 D, E).

Thorax ground color black. Chaetotaxy: acrostichals 2(3)+4, dorsocentrals 2+3, intra-alars 1+3, supra-alars 2, postalars 2, postpronotals 3, notopleurals 2, scutellum with 1 apical, 1 marginal, 1 discal and 1 basal bristles. Pleuron with meropleurals 11; katepisternal bristles 1(2): 1, prosternum, metasternum, proepimeron, proepisternum and postalar wall all bare.

Wing hyaline ( Fig. 22 A); subcostal sclerite and basicosta yellow, bare; tegula yellow, with fine black bristles; costal spine not differentiated; vein R1 bare, one ventral and three dorsal bristles at node of R2+3-R4+5; cell r4+5 broadly open; lower calypter yellowish white.

Legs black; fore femur with one row of dorsal bristles (about 9), one row of ventral bristles (about 14) and one row of posterodorsal bristles (about 8), and with slender bristles along dorsal and posteroventral margins, fore tibia with one apical dorsal, one sub-median ventral and two posterodorsal bristles, and with one row of anterodorsal bristles (about 5); mid femur with one row of anterior bristles in basal half (about 5) and one row of ventral bristles in basal half (about 4), mid tibia with three anterodorsal, one or two median ventral, one sub-median posterior and three posterodorsal bristles, and with long bristles along anteroventral, ventral and posteroventral margins; hind femur with one row of anterodorsal bristles and one row of ventral bristles, and with elongated bristles along anterodorsal, anterior and ventral margins, hind tibia with one sub-median anteroventral and three posterodorsal bristles, one row of anterodorsal bristles (about 9, two strong).

Abdomen long oval with yellowish gray pollinosity, tergites with black spots; tergites 4, 5 and 6 with complete row of marginal bristles, epandrium black, tergites 1+2 all black except lateral part, the spot on tergite 3 fused with the spot on tergites 1+2, tergite 4 with three distinct triangular spots on the posterior margin, tergite 5 with three small spots, epandrium black, sternites 1−4 with dense bristles. Terminalia see Fig. 22 B, F.
