Tanycarpa mitis Stelfox, 1941: 5. Holotype: female, USNM (examined). Chen and Wu 1994: 140 (redescription, range extension); van Achterberg 1976: 12 (diagnosis relative to T. punctata).
Material examined. 2 ♀ China, Ningxia: Liupanshan, Migangshan, 22 –VIII– 2000, Zhihui Lin (1 FAFU, 1 USNM).
Diagnosis. Eye as long as temple length in dorsal view; midpit elliptical; mesoscutal lobes moderately convex, smooth and with dense setae medially, glabrous laterally; T 1 long and narrow, 1.70 × longer than apical width; propodeum with longitudinal ridge in basal 1 / 3, smooth laterally on both sides adjacent to ridge, ridge then breaking into 2 irregular transverse ridges, and with several longitudinal irregular ridges on apical 0.5 of propodeum.
Distribution. Austria; China (Fujian, Hubei and Ningxia); Czech Republic; Ireland; Russia (Primor'ye Kray, Sakhalin Oblast, Saint Petersburg); United Kingdom.
Remarks. The male is similar morphologically to the female. Tanycarpa mitis is similar morphologically to T. gracilicornis. The differences between the two species are noted in the key, especially as follows: T. mitis has 22– 29 flagellomeres and ovipositor sheath short, much shorter than hind tibia; T. gracilicornis has 30–40 flagellomeres and ovipositor sheath long, much longer than hind tibia. Tanycarpa mitis also has more robust flagellomeres and legs compared to congeners. Further, the pterostigma is almost linear and much narrower in T. mitis than other congeners.
