Type material.
Holotype: • ♀ ( ICXU) on slide (Fig. 1 H View Figure 1 ): China, Xinjiang, Xinhe , 41°32'33"N, 82°36'12"E, 15.VII.2001, Wei Wu, sweeping GoogleMaps . Paratypes (all in ICXU): China, Xinjiang: • 1 ♀, Jinghe , 44°36'03"N, 82°53'22"E, 15.VII.2001, Hongying Hu et al., sweeping GoogleMaps ; • 4 ♀♀, Xinhe , 41°32'38"N, 82°36'16"E, 1.VI.2001, Wei Wu, sweeping GoogleMaps .
Diagnosis.
Antenna (Fig. 1 B View Figure 1 ) with scape smooth, almost as long as pedicel; F 2 as long as F 6; clava longer than combined length of three preceding flagellomeres and longer than combined length of F 1 – F 3, with eight mps. Mesosoma smooth; pronotum (Fig. 1 C View Figure 1 ) with four setae on each side along anterior margin; scutellum (Fig. 1 C View Figure 1 ) with a frenal row of foveae, they are distinctly wider and apparently shallower; propodeum (Fig. 1 C View Figure 1 ) with a complete median carina shaped posteriorly as an inverted narrow Y-shape. Ovipositor (Fig. 1 G View Figure 1 ) slightly exserted beyond gastral apex.
Description.
Female ( holotype and paratypes). Body length 426–438 μm ( n = 6). Head (Fig. 1 A View Figure 1 ) in frontal view 0.6 × (0.6–0.8 ×) as high as wide. Antenna (Fig. 1 B View Figure 1 ) with scape smooth, 1.8 × (1.8–1.9 ×) as long as wide (including short radicle), almost as long as pedicel; pedicel 2.1 × (1.5–2.1 ×) as long as wide, 2.3 × (1.9–2.4 ×) as long as F 1; F 1 the shortest funicular; F 2 as long as F 6 and both the longest funiculars; F 4 and F 5 subequal in length; F 6 with one mps; clava 3.3 × (2.9–3.7 ×) as long as wide, longer than combined length of three preceding flagellomeres and longer than combined length of F 1 – F 3, with eight mps.
Mesosoma smooth, 1.2 × (1.1–1.3 ×) as long as wide; pronotum (Fig. 1 C View Figure 1 ) divided mediolongitudinally, with four setae on each side along the anterior margin; mesoscutum (Fig. 1 C View Figure 1 ) 0.5 × (0.5–0.6 ×) as long as wide, longer than scutellum; scutellum (Fig. 1 C View Figure 1 ) 0.6 × (0.5–0.6 ×) as long as wide, with a frenal row of foveae, they are distinctly wider and apparently shallower; propodeum (Fig. 1 C View Figure 1 ) with a complete median carina shaped posteriorly as an inverted narrow Y-shape. Forewing (Fig. 1 D View Figure 1 ) 4.1 × (4.1–4.4 ×) as long as wide; disc hyaline, densely setose beyond venation, with discal setae originating behind stigmal vein (Fig. 1 E View Figure 1 ), many of them 5.3–7.2 μm long; longest marginal seta 1.0 × (0.6–1.0 ×) greatest width of forewing; Hind wing (Fig. 1 F View Figure 1 ) 28.9 × (27.2–31.4 ×) as long as wide; disc hyaline, with two rows of setae; longest marginal seta 5.8 × (5.6–6.4 ×) greatest width of hind wing.
Metacoxa (Fig. 1 C View Figure 1 ) smooth, in lateral view a little longer than petiole. Petiole (Fig. 1 C View Figure 1 ) 1.3 × (1.3–1.5 ×) as long as wide, in dorsal view with inconspicuous vertical striations and expanded basally. Ovipositor (Fig. 1 G View Figure 1 ) 1.0 × (1.0–1.1 ×) as long as gaster, slightly exserted by ~ 0.1 × its own total length beyond gastral apex; ovipositor 1.7 × (1.5–1.8 ×) length of mesotibia and 1.5 × (1.3–1.5 ×) length of metatibia.
Measurements of the holotype (μm). Head height: width: 60: 101; mesosoma (in dorsal view) length: width: 115: 95; mesoscutum length: width: 41: 77; scutellum length: width: 30: 53; median carina length: 29; petiole length: width: 28: 22; gaster length: width: 130: 90; ovipositor length: 136; exserted part of ovipositor: 13; antennal segments length: width: scape: 26: 15; pedicel: 25: 12; F 1: 11: 5; F 2: 18: 6; F 3: 11: 6; F 4: 13: 7; F 5: 12: 7; F 6: 18: 8; clava: 56: 17; forewing length: width: 274: 66; longest marginal seta length: 65; discal setae length: 5–7; hind wing length: width: 231: 8; longest marginal seta length: 46; mesotibia length: 79; metatibia length: 89.

Etymology.
The new species is a noun in apposition meaning “ a short scape ” in Latin.
Distribution.
China ( Xinjiang).
Comments.
In this new species, the scape is approximately as long as the pedicel, thus distinguishing it from most species within the subgenus in which the scape is usually longer than pedicel. The unique combination of the posterior margin of the scutellum with a frenal row of foveae that are distinctly wider and apparently shallower and the median carina being complete, forming an inverted Y-shape, separates it from all the other described species in the subgenus.
