description: 17. Sphecapatodes xinjiangensis sp. nov.    
(Figs 27, 28B, F, 29A, 30F)  
 Diagnosis. fore first tarsomere curved and with dense ventrobasal setulae curving downwards, tip bent forward, length of second fore tarsomere equal to or shorter than length of first fore tarsomere. Syntergite 1+2 with an inverted mountain-like vitta. WIP with a broad yellow band along posterior wing margin and a broad magenta spot on apical part.   
 Description. Male. Body length 6.5 mm.   
Head. Eye bare, red. Fronto-orbital plate, parafacial plate, and postocular strip black with silvery-white pollinosity; parafacial with sparse and short setulae. Fronto-orbital plate with black setulae. Frontal vitta black, with thick silvery-white pollinosity, becoming narrow in anterior (lower) part, ratio between narrowest and widest 0.34; frons at vertex 0.40 × head width; frontal triangle reaching to lunule; frontal without setulae; frontal row of 8 to 12 setae, becoming closer in anterior part; outer vertical seta differentiated from postocular setae and about 0.80× as long as inner vertical seta, one pair of reclinate orbital setae, two pairs of proclinate orbital setae. Ocelli red, with one pair of strong ocellar setae, ocellar setae directed laterally. Gena ground color brown, with sparse and short black setulae and silvery-gray pollinosity, 0.15 × eye height in lateral view. Antenna dark brown. Postpedicel 1.10 × as long as pedicel. Pedicel with one long seta. Arista black-brown, bare or micro-pubescent, basal third swollen; more than 3 rows of postocular setae. Palpus orange, slightly expanded at apex. Facial ridge with 3‒4 fine black setulae in lower part. Vibrissa well developed.  
 Thorax, ground color black; scutum and scutellum with thick grayish-white pollinosity. Chaetotaxy: acrostichals 2 + 2(1), dorsocentrals 2(3) + 3, intra-alars 1 + 3, supra-alars 2, postpronotals 2, postalars 2, notopleurals 2, scutellum with 2 or 3 pairs of discal and 3 pairs of marginal setae. Katepisternal setae 1 + 1. Scutellum with black setulae on both two sides in distal margin. Wing hyaline, with an apical spot; subcostal sclerite and basicosta bare and yellow. Tegula dark yellow, with black setulae. Costal spine not differentiated; 3rd costal section slightly longer than 5th; vein R 1 bare, 2 fine black setulae at node of R 2+3 and R 4+5; cell r 4+5 open. WIP (Fig. 30F) with a broad yellow band along posterior wing margin and a broad magenta spot on the apical part. Calypter and halter yellow. Legs dark black, claws and pulvilli small; fore femur with numerous long setulae posteriorly and one row of ventral setae, fore tibia slightly narrower in basal third, with 1 posteroventral, 0 or 1(short) apical posterodorsal, 5 anterodorsal setae, and dense yellow setae on ventrally in distal half; fore tarsus curved and with dense basal setulae curving downwards on ventral surface, tip bent forward; mid femur with 2 apical posterodorsal setae, mid tibia with 3 anterodorsal setae, 2 submedian ventral setae, 3 posterodorsal setae, and 2 posterior setae; hind femur with a row of anterodorsal setae and a row of ventral setae; hind tibia with a row of anterodorsal setae, 4 anteroventral setae, and 5 posterodorsal setae.   
Abdomen with dense gray pollinosity. Syntergite 1+2 with an inverted mountain-like vitta, light gray; tergite 3 with three distinct black spots, a black median stripe, and one pair of median marginal setae; tergite 4 with an inconspicuous median spot and a complete row of marginal setae. Terminalia: Cercus and surstylus gently curved forward in profile. Pregonite long, tapering distally, postgonite pointed, and with a long basal seta. Phallus with well-developed ventral and dorsal plates. Distiphallus with a distinct ventral swelling (Fig. 28B, F).  
 Female. Unknown.   
 Type material. Holotype ♂ [BFUM]: Xinjiang, Altay, Kalamaili, 2.V.2015, MZ & CW leg. Paratypes: 3 ♂♂ [BFUM]: Xinjiang, Altay, Kalamaili, 2.V.2015, MZ & CW leg.   
 Etymology. The new species is named after its type locality, the Chinese province Xinjiang.   
 Distribution. China (Xinjiang).   
 Remarks. This new species is similar to Sphecapatodes superciliosa sp. nov., but differs from it as follows: postpedicel 1.10 × as long as pedicel, parafacial with sparse setulae, fore tarsus curved and with dense ventrobasal setulae curving downwards (Fig. 29A), distiphallus with a distinct ventral swelling, without a constriction before the membranous tip (Fig. 28F); WIP with a broad yellow band along posterior wing margin and a broad magenta spot on apical part (Fig. 30F).
