Wings. Pterostigma linear, r arising from basal 1/4; 3RSb slightly sinuate; 1cu-a small, postfurcal; 1CU1:1CU2=1:5–1:8; 1st subdiscal cell closed; r:3RSa:3RSb:2RS:r-m=4:21:68:19:11; 2nd submarginal cell 1.70× longer than wide; 2CUb arising just below middle of 1st subdiscal cell ( Fig. 28 ).

Legs. Hind leg almost smooth; tarsal claws slender, simple, and large; femur, tibia, and basitarsus of hind leg 5.00×, 9.50×, and 7.00× longer than wide, respectively.

Metasoma. T1 1.90× longer than apical width, apical width 1.88× wider than basal width, apical part medially protruding, longitudinally rugose in apical 1/3; spiracles small, not protruding ( Fig. 29 ); dorsal carinae developed, not converging; laterope medium-sized and narrow; ovipositor sheath 0.40× longer than metasoma, 1.40× longer than T1, 0.73× length of hind tibia ( Fig. 30 ).

Male. Head. Head 2.33–2.56× wider than high; antenna with 21–24 flagellomeres; eye 1.20–1.30× longer than temple length in dorsal view.

Mesosoma . 1.55× longer than high; mesoscutum 0.86× longer than wide; precoxal sulcus deep, short, wider posteriorly than anteriorly, crenulate and somewhat curving up posteriorly; mesoscutum medial lobe with sparse pubescence, lateral lobes almost entirely glabrous.

Wings. 3RSb straight; 1cu-a small, interstitial; r short and wide, as long as width of pterostigma; 2nd submarginal cell 1.55–1.75× longer than wide; 2CUb arising below middle of 1st subdiscal cell; 2CUa:2cu-a=2:1.

Metasoma. T1 2.20× longer than apical width, apical width 1.30–1.60× longer than basal width.

Etymology. This species is named after the very distinctive propodeal areola.

Distribution. China (Ningxia).

Remarks. Tanycarpa areolata is most similar morphologically to T. chors , particularly the vertex with dense short white pubescence. The two species are differentiated from one another in the remarks for T. chors .
