Katepisternal setae 1 + 1. Wing hyaline, with one darker apical spot (Fig. 26E); subcostal sclerite and basicosta bare and yellow; tegula dark yellow, with black setulae; costal spine not differentiated; third costal section approximately equal to the fifth; vein R 1 bare; 2‒3 fine black setulae at node of R 2+3 and R 4+5; cell r 4+5 open; WIP (Fig. 30E) with a clearly demarcated green band between an inner magenta band and an outer blue band, with a narrow yellow band along posterior wing margin, and a magenta spot on apical part. Calypter white, halter yellow. Legs dark. Claws and pulvilli small. Fore femur with numerous long setae posteriorly, one ventral row of setae. Fore tibia slightly narrowed basally, with 1 posterior seta, 1 posterodorsal seta and one row of anterodorsal setae, with dense yellow setae on ventral surface in distal half, fore tarsus with dense setulae basally on ventral surface; mid femur with 2 apical posterodorsal setae, mid tibia with 3 anterodorsal setae, 2 ventral setae and 1 row of posterodorsal setae; hind femur with 1 row of anterodorsal setae, hind tibia with 1 row of anterodorsal setae, 4‒5 anteroventral setae, and 5‒6 posterodorsal setae.

Abdomen with dense gray pollinosity. Syntergite 1+2 black; 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; marginal setae on tergite 5 weak. Terminalia: Cercus straight and sharp distally, surstylus with apex straight and with an oval rounded tip in lateral view, long. Pregonite long, tapering distally, postgonite with a long middle seta. Phallus with well-developed ventral and dorsal plates. Distiphallus distinctly Swollen, with a constriction before the membranous tip. (Fig. 28A, F)

Female. Unknown.

Type material. Holotype ♂ [BFUM]: Xinjiang, Altay, Kalamaili, 29.IV.2015, MZ & CW leg. Paratypes: 13 ♂♂ [BFUM]: Xinjiang, Altay, Kalamaili, 29.IV.2015, MZ & CW leg.

Etymology. The specific name is formed from “ super ” meaning above average or extraordinary, and “ ciliosa ” meaning hairy or setose. It refers to the most distinctive feature of this species: dense setulae on the posteroventral surface of the fore first tarsomere (Fig. 29B).

Distribution. China (Xinjiang).

Remarks. The new species belongs to the Sphecapatodes ornata Villeneuve group according to following characters: posterior part of frontal vitta (at vertex) three times as broad as anterior part; frontal bristles fine and not crossed; postpedicel short, about 1.20 × as long as pedicel. It closely resembles to S. kaszabi Rohdendorf & Verves, 1980 and Sphecapatodes xinjiangensis sp. nov. in the wing venation and in the presence of black abdominal spots, but it differs from it by having dense setulae curving anteriorly on the ventral surface of the fore tarsus (Figs 26A (box), 29B), WIP with a slightly lighter and shorter magenta spot on the apical part, and surstylus with apex straight and with an oval rounded tip in lateral view (Figs 28A, 30E).
