Head. Antenna with 24 flagellomeres, F1 (including annulus) 1.80 × longer than F2 ( Fig. 13 ), F1, F2, and penultimate flagellomere 5.00, 2.50, and 1.25 × longer than wide, respectively, with protruding ridge between antenna ( Fig. 14 ). Labial palp slender. Face smooth and shiny, with short pubescence medially and longer pubescence laterally ( Fig. 13 ). Eye 0.70 × length of temple (in dorsal view). Temple nearly parallel-sided behind eye ( Fig. 14 ). Frons flat and smooth. Clypeus strongly convex. Malar space without suture, 0.10 × length basal width of mandible; mandible with fourth protuberance divided into two small teeth, medial length 2.00 × longer than maximum width ( Fig. 12 ).

Mesosoma. 1.40 × longer than high. Mesopleuron smooth, precoxal sulcus narrow, deep, and smooth ( Fig. 15 ). Metapleuron smooth dorsally, ventrally with rugae. Episternal scrobe deep and narrow. Mesoscutum smooth, glabrous except some setae where notauli would extend if complete ( Fig. 18 ); notauli deep and crenulate at anterior half of mesoscutum, posterior half smooth and without trace of notauli; midpit deep and elliptical, about 2.00 × wider than width of notauli ( Fig. 18 ). Scutellar sulcus with four carinae ( Fig. 18 ). Scutellum smooth. Metanotum protruding dorsally and largely smooth (other specimens of this species frequently rugose), with complete but weakly protruding mid-longitudinal carina. Propodeum without areola, extensively rugose medially and with few short rugae near mid-longitudinal carina, mid-longitudinal carina of propodeum complete, strongly protruding ( Fig. 18 ); propodeal spiracle small, round, and sub-medially situated ( Fig. 19 ).

Wings. Fore wing ( Fig. 11 ): vein r arising nearly from base of pterostigma; vein 2RS of both wings mostly tubular; r: 3RSa: 3RSb = 2: 4.5: 9.4; 2RS: 3RSa: r-m = 19: 50: 20; 1CU-1: 1CU-2 = 2: 7; vein 1m-cu distinctly postfurcal; vein 2cu-a about as long as vein 2CUa.

Legs. Hind coxa smooth with some pubescence. Tarsal claws slender ( Fig. 16 ). Length of femur, tibia, and basitarsus of hind leg 5.70 ×, 9.00 ×, and 7.00 × longer than wide, respectively. Length of hind tibial spurs 0.25 × and 0.37 × length of hind basitarsus. Inner side of apex of hind tibia not depressed and normally with yellow setae ( Fig. 16 ). Hind tarsus with long setae ( Fig. 16 ).

Metasoma. T1 1.20 × longer than apical width, apical width 2.00 × longer than basal width; medial part and posterior half rugose, rest of T1 smooth ( Fig. 19 ); lateral longitudinal carinae distinctly converging at basal half but not connected and then parallel to posterior margin of T1 ( Fig. 19 ). Width of dorsope shorter than half width of basal T1 and spiracle protruding. Length of ovipositor sheath 1.75 mm, 0.56 × length of fore wing, and 1.60 × longer than hind tibia; ovipositor sheath setiferous, setae increasing in length from base to apex except for pair of very short setae near tip ( Figs 16 ).

Color. Body mostly dark reddish brown. Mandible reddish brown, head reddish brown, antenna brown, scape and pedicel dark yellow brown, palpi yellowish, legs mostly brownish yellow, distal tip of femur and tibia brown, pterostigma dark brown, T1 and mesosoma black brown, abdomen reddish brown except T1.

Male. Most of characters are the same as female. Antenna with 35–37 flagellomeres; temple distinctly convex anteriorly, roundly narrowed posteriorly; mandible rugose with transverse carinae; notauli deep and crenulate in 2/ 3 of mesoscutum, smooth posteriorly, almost reaching midpit; midpit elliptical, deep, and smooth; T1 rugosestriate and with strong dorsal carinae united nearly to its middle, rugose laterally.

Material examined. Holotype, ♀, CHINA Ningxia Liupanshan Xixia, 17-?-2001, Qinge Ji ( BIIC) . Paratypes, 1 ♀, CHINA Ningxia Liupanshan Xixia, 17-?-2001, Qinge Ji ; 1 ♀, CHINA Ningxia Liupanshan Jingyuan, 15-?- 2001, Guanghong Liang ; 1 ♂, CHINA Ningxia Liupanshan Migangshan, 22-?-2001, Zhihui Lin ; 1 ♀ 3 ♂, CHINA Qinghai Qingde, 17-?-2008, Qiong Zhao ; 1 ♀ 2 ♂, CHINA Qinghai Qilianshan 11-?-2008, Qiong Zhao ; 3 ♀ CHINA Qinghai Minhe, 6-?-2008, Qiong Zhao ; 1 ♀, CHINA Qinghai Xining Beijiao 6-?-2008, Qiong Zhao ; 1 ♀, CHINA Qinghai Xining Taershan, 1-?-2008, Qiong Zhao ; 1 ♀, CHINA Qinghai Datong, 20-?-2008, Qiong Zhao ; 1 ♀, CHINA Gansu Xinglongshan, 2-?-2008, Qiong Zhao ( BIIC).

Comparative diagnosis. Anisocyrta xiaoliyaoae is close to A. shelichovi ; it is easily identified by the longer ovipositor and propodeum of male and female with high mid-longitudinal carina. They also differ in color, with A. xiaoliyaoae lighter than A. shelichovi .

Variation. There are some dark specimens and some reddish-brown specimens. Antenna of ♀ with 24–27 flagellomeres, antenna of ♂ with 33–35 flagellomeres; length of fore wing of ♀ 2.75–3.13 mm, length of body of ♀ 2.50–3.13 mm; length of fore wing of ♀ 2.75–4.00 mm; length of body of ♂ 2.38–3.75 mm.

Host. Unknown.

Etymology. Named in honor of Xiaoli Yao, elder sister of the first author.

Distribution. China (Ningxia, Qinghai, Gansu).
