description: Alloxiphia qinlingia Wei, sp. nov. (Fig.2)   
Description. Female. Body length 14.0 mm (Fig. 2a). Black; clypeus, supraclypeal area, a stripe on lower inner orbit and malar space, an elliptical macula on lateral of postocellar area, a long and narrow stripe on postorbit, a small lateral macula on abdominal tergites 2, 4 and 5, narrow posterior margin of tergite 10, a middle short stripe on ovipositor sheath, yellow white. Body hairs silver. Legs black, a small basal dot on fore and middle tibiae, and basal 1/3 of hind tibia white. Fore wing hyaline in basal 2/3 and infuscate in apical 1/3, hind wing hyaline in basal 3/4 and infuscate in apical 1/4, pterostigma black.  
Body hairs very short. Clypeus with some large and sparse punctures; frons, ocellar area, inner orbits and supraclypeal area coarsely rugose mixed with irregularly carinae (Figs 2b–d), anterior third of postocellar area rugose, lower half of hind orbit densely punctured with some longitudinal carinae (Fig. 2c), upper part of hind orbit smooth with sparse large punctures, postocellar area largely and temple smooth with some minute punctures (Fig. 2b); lateral slope of mesoscutellum rugose with some small smooth patch; abdominal tergite 1 coarsely punctured, inner margin smooth; tergites 2–5 densely microsculptured, almost mat (Fig. 2i); other tergites more weakly microsculptured toward apex.  
Maxillary palpomeres 3 and 4 each more than twice as long as broad, palpomere 5 as long as palpomeres 3 and 4 together, without apical process (Fig. 2g); labial palp stout, palpomere 1 as long as palpomere 3 and 2 times as long as palpomere 2 (Fig. 2f); flat part of malar space shorter than radius of median ocellus; eyes short and broad, inner margins distinctly divergent downwards, distance between eyes at level of antennal toruli slightly broader than longest axis of eye; antenna with 17 antennomeres and about 1.7 times as long as head breadth, antennomeres 1 and 3 strongly bent, length ratio of basal 5 antennomeres about 45: 20: 44: 24: 24 (Fig. 2k), each flagellomere longer than broad and distinctly microsculptured; dorsum of mesoscutellum distinctly narrowed backwards; vein 2r in fore wing meeting cell 1Rs at apex, petiole of hind anal cell clearly shorter than cu-a; claw with a small inner tooth remote from outer tooth (Fig. 2h); ventral margin of ovipositor sheath almost straight, length of ovipositor sheath about 0.41 times as long as abdomen, apical sheath as long as basal sheath; cercus short and almost straight, about 1/5 length of apical sheath (Fig. 2e); sheath in dorsal view gradually narrowed toward apex (Fig. 2j).  
Male. Unknown.  
Etymology. This new species is named after the type locality, Huayin, located in Mt. Qinling.  
Distribution. China (Shaanxi).  
Material examined. Holotype. ♀, Huayin, Shaanxi, China, September 2, 2019, Liangdong Song leg.  
 Remarks. This new species is similar to A. tianmua Wei, sp. nov. from Zhejiang, but differs from the latter by the following: the clypeus and supraclypeal area entirely yellow white, the lateral of postocellar area and hind orbit with distinct yellow white maculae, the abdominal tergite 8 black without lateral white macula, the hind tibia white in basal third, the metabasitarsus black; the apical 1/3 of hind wing and apical 1/4 of hind wing infuscate; the vein 2m-cu remote from 1r-m, the petiole of hind wing clearly shorter than cu-a; the antennomeres 1 and 3 distinctly bent and subequal in length.
