Materials Examined
Type material.Holotype: ♀ China, Ningxia: Liupanshan, Longtan, 15 –VIII– 2001, Zhihui Lin (FAFU). Paratypes:2 ♀ 1 ♂China, Ningxia: Liupanshan, Erlonghe, 23 –VIII– 2001, Jianquan Yang (1 ♀ 1 ♂FAFU, 1 ♀ USNM).
Diagnosis
Diagnosis. Frons glabrous except a few setae laterally (Fig. 15); vertex sparsely setose (Fig. 15); precoxal sulcus deep, curved, extending 4 / 5 th length of mesopleuron (Fig. 18); mesoscutum smooth, medial lobe with sparse pubescence (Fig. 19); propodeum without distinct longitudinal ridge but diverging into two oblique ridges from basal 1 / 4 – 1 / 5, at end of oblique ridges with several oblique irregular ridges on apical 2 / 3 of propodeum, forming areola with several transverse ridges apically, almost glabrous (Fig. 19); scutellar disc setiferous, somewhat triangular in outline (Fig. 19); ovipositor sheath shorter than metasoma.
Description
Female (Figs. 15–22). Head. Antenna with 25–29 flagellomeres, 1 st flagellomere 1.57 × longer than 2 nd, 1 st and 2 nd flagellomeres 4.20–5.50 × and 2.40 –4.00× longer than their widths, respectively, without long setae (Fig. 15); eye glabrous, 1.33 × longer than temple length in dorsal view; temple expanded behind eye (Fig. 15); frons almost flat, smooth without pubescence; occipital tubercles absent; face somewhat convex; temple smooth and with sparse pubescence (Fig. 15); anterior tentorial pits medium-sized, deep; clypeus convex, punctulate; apical margin of clypeus straight; head 1.75 × wider than medial height (Fig. 15); mandible expanded dorsally, 1.45–1.63 × longer than wide, 3 rd tooth large, rounded, clearly separated from 2 nd tooth nearly at right angle, 2 nd tooth wide, relatively long and pointed, basal width 1.00× length, 1 st tooth as large as 3 rd tooth, with hemispherical incision between 1 st and 2 nd tooth (Fig. 17). Mesosoma.1.30–1.35 × longer than high; propleuron smooth with some crenulae medially; mesoscutum 0.80– 0.90 × longer than wide (Fig. 19); notauli distinctly crenulate basally, obliterated posteriorly; midpit long and narrow, nearly 1 / 4 of mesoscutum length; mesoscutal lobes moderately convex, nearly glabrous with only medial lobe basally and near midpit sparsely setose (Fig. 19); scutellar sulcus deep and wide, with 1 rather weak longitudinal carina; subalar area almost smooth, with transverse and shallow smooth depression anteriorly; precoxal sulcus deep, curved, and 4 / 5 mesopleuron length (Fig. 18); scutellar disc convex, smooth; propodeum without distinct longitudinal ridge but dividing into two oblique ridges in basal 1 / 4 – 1 / 5, at end of oblique ridges with several oblique irregular ridges on apical 2 / 3 of propodeum, forming areola sometimes with several transverse ridges, nearly smooth (Fig. 19). Wings. Pterostigma narrowly wedge-shaped (Figs 20, 22); r shorter, length less than pterostigma width; 3 RSb straight; 1 cu-a small, weakly postfurcal; 1 CU 1: 1 CU 2 = 1: 16; 1 st subdiscal cell closed; r: 3RSa: 3 RSb: 2 RS:rm= 4: 17: 63: 18: 8; 2 nd submarginal cell 1.70–1.90 × longer than wide; 2 CUb arising from middle of 1 st subdiscal cell (Fig. 20). Legs.Hind leg almost smooth; tarsal claws slender, simple, and rather large; femur, tibia, and basitarsus of hind leg 4.70 ×, 11.00×, and 6.70 × longer than their widths, respectively (Fig. 22). Metasoma. T 1 1.70–1.80 × longer than apical width, protruding medially, with many ridges laterally; spiracles subdorsal, protruding (Fig. 21), dorsal carinae developed, not converging in basal 1 / 3, laterope medium-sized and wide (Fig. 21); ovipositor sheath shorter than metasoma, 2.00× longer than T 1, 0.73 × longer than hind tibia (Fig. 22). Color. Body dark brown; mandible dark yellow except apex of tooth 2 darker; antenna brown; legs yellow and smooth; pterostigma pale yellow; metasoma except T 1 reddish brown. Male. Not substantially different from female.
Etymology
Etymology. The species name refers to the fact that this species is very similar to T. mitis (as well as T. gracilicornis).
Distribution
Distribution.China (Ningxia).
Discussion
Remarks.Tanycarpa similis is similar morphologically to T. gracilicornis and T. mitis based on the filiform apical three flagellomeres and presence of a mesoscutal midpit. Tanycarpa gracilicornis has longer antennae, with 30-40 flagellomeres; the antennae of T. mitis and T. similis are shorter and have 22–29 flagellomeres. As for T. mitis and T. similis, the propodeum of T. mitis has a longitudinal ridge, and the 2 nd submarginal cell is longer than in T. similis.
