Type material. Holotype: ♂ China, Ningxia: Liupanshan, Liangdianxia, 21-VIII-2001, Jianquan Yang ( FAFU).

Vertex mostly smooth with sparse pubescence near epicranial suture ( Fig. 31 ); face with pubescence, somewhat convex, 1.40× wider than high ( Fig. 32 ); notauli distinctly crenulate basally and protruding as tubercles at edge of anterior declivity ( Fig. 35 ); mesoscutum sparsely setose ( Fig. 35 ); T1 2.30× longer than apical width, apical width 1.22× longer than basal width ( Fig. 35 ); 1cu-a small, interstitial ( Fig. 36 ); propodeum without longitudinal ridge in basal 1/3, smooth and then with large medial, square areola with dense pubescence ( Fig. 35 ).

Male ( Figs. 31–36 ). Head. 1st flagellomere 1.40× longer than 2nd, 1st and 2nd flagellomeres 5.20× and 4.50× longer than wide respectively, without long setae ( Fig 31 ); eye glabrous, 1.63× longer than temple length in dorsal view; temple roundly narrow behind eye ( Fig. 32 ); frons almost flat, with dense short pubescence; occipital tubercles absent; face pubescent medially, both sides glabrous, somewhat convex, 1.40× wider than high; vertex mostly glabrous with sparse pubescence ( Fig. 31 ); anterior tentorial pits medium-sized, deep; clypeus convex, punctulate; apical margin of clypeus straight ( Fig. 32 ); head 1.72× wider than medial height; mandible slightly expanded dorsally, tooth 1 dorsal edge upcurved, otherwise mandible almost parallel-sided, 1.90× longer than wide, 3rd tooth large, rounded, 1st tooth separated from 2nd tooth by almost a right angle, 2nd tooth wide, long and pointed, 1.50× longer than wide, 1st tooth smaller than 3rd tooth, with hemispherical incision between 1st and 2nd tooth ( Fig. 33 ).

Mesosoma . 1.54× longer than high; propleuron smooth; notauli distinctly crenulate basally and with tubercles at edge of anterior declivity, obliterated posteriorly; midpit small and round ( Fig. 31 ); mesoscutum with medial lobe sparsely setose, both sides glabrous ( Fig. 35 ); scutellar suture deep and wide with 1 very weak longitudinal carina ( Fig. 31 ); subalar area smooth ( Fig. 34 ); precoxal sulcus shallow, wide and curved; subalar area almost smooth, with transverse and shallow smooth depression anteriorly, crenulate ventrally ( Fig. 34 ); scutellar disc strongly convex, smooth and only margins with sparse pubescence ( Fig. 35 ); propodeum without longitudinal ridge in basal 1/3, with large square areola medially with dense pubescence, other parts of propodeum glabrous ( Fig. 35 ).

Wings. Pterostigma linear and narrow, r arising from basal 1/4 and medially slightly narrower than laterally; 3RSb straight; 1cu-a small, antefurcal; 1st subdiscal cell closed; r:3RSa:3RSb:2RS:r-m=3:17:67:18:9; 1m-cu strongly postfurcal; 2nd submarginal cell 1.76× longer than wide; 2CUb arising below middle of 1st subdiscal cell; 2CUa:2cu-a=2:1; 1cu-a short, 1st subdiscal cell closed, apical width 2.70× longer than basal width ( Fig. 36 ).

Legs. Hind leg almost smooth; tarsal claws slender, simple, and large; femur, tibia, and basitarsus of hind leg 4.70×, 8.70×, and 7.00× longer than wide, respectively.

Metasoma. T1 2.30× longer than apical width, apical width 1.22× longer than basal width, protruding medially, with many ridges laterally; spiracles small, not protruding ( Fig. 35 ), dorsal carinae developed, not converging; laterope medium-sized and narrow ( Fig. 35 ).

Color and size. Body reddish brown; mandible yellow except apex of tooth 2 reddish; antenna brown; legs yellow and smooth; pterostigma light brown; metasoma reddish brown. Body length 2.6 mm.

Female. Unknown.

Etymology. This species is named after the linear and narrow fore wing stigma.

Distribution. China (Ningxia).

Remarks. Tanycarpa lineata and T. chors appear to be most similar to each other morphologically. However, T1 is slender in T. lineata , its length 2.30× longer than its width apically and its width apically 1.22× longer than its width basally; T1 is robust in T. chors , its length 1.70× longer than its width apically and its width apically 2.10× longer than its width basally.
