Description.

Illustrated ♀ from Liupan Mt., length of body 5.6 mm (of fore wing 5.1 mm).

Head. Antenna with 20 segments; frons coarsely punctate, with smooth interspaces narrower than punctures and with some rugae anteriorly (Fig. 88); vertex largely smooth and strongly shiny posteriorly, but spaced moderately punctate anteriorly (Fig. 87); temple smooth except some punctures near eye and mandible (Fig. 89); head gradually narrowed behind eyes, eye in dorsal view 1.1 times as long as temple (Fig. 87); occipital carina narrow, non-lamelliform and smooth dorsally (Fig. 87); supra-antennal elevations medium-sized (about half as long as scapus), outer side subvertical anteriorly and with few rather small punctures and apically with few striae (Fig. 87); clypeus slightly concave medio-ventrally and with blunt tubercle above it.

Mesosoma. Length of mesosoma 1.5 times its height; propleuron largely rugose; mesopleuron below transverse mesopleural groove rugulose, above groove densely rugose but posteriorly largely smooth (Fig. 84); transverse mesopleural groove wide, deep and coarsely crenulated; mesosternum mainly transversely aciculate; notauli rather wide, deep and coarsely crenulated; middle lobe of mesoscutum transversely rugulose, but posteriorly with some rugae and anterior pair of smooth stripes rather conspicuous, lateral lobe with coarse rugae but laterally largely smooth or superficially rugulose (Fig. 83); scutellar sulcus rather wide and coarsely crenulated; scutellum reticulate-rugulose and medially slightly longitudinally depressed laterally (Fig. 83); metanotum rugose and medially flattened, but submedially convex (Fig. 83); propodeum slender, lateral sides nearly straight, its surface shiny, finely rugose anteriorly and superficially rugulose posteriorly (Fig. 83); posterior propodeal carina narrow lamelliform medially and strongly arched, foramen medially 0.4 times higher than wide basally.

Wings. Fore wing: length of vein 1-M 1.7 times as long as vein 1-SR (Fig. 82); second submarginal cell 1.3 times as long as third cell.

Metasoma. First tergite 0.6 times as long as its apical width, smooth and medially largely depressed (Fig. 85); metasoma smooth and strongly shiny, third–fifth tergites superficially punctulate (Fig. 86); second sternite strongly shiny and convex; second–fourth sternites superficially spaced punctulate or finely punctate; third sternite slightly concave and about 0.3 times as long as second sternite (Fig. 86).

Colour. Black; palpi dark brown basally and pale brown apically; antenna pale brown, but scapus and apical 0.4 of antenna darkened; inner orbita slightly brownish near level of antennal sockets; mandible mainly dark brown, but medially pale brown; sixth tergite yellowish ivory; robust hind trochanter and trochantellus mainly white except some slightly brownish small patches; fore and middle tibiae and tarsi brownish yellow, but middle tibia dark brown posteriorly; remainder of legs, tegulae and pterostigma dark brown; wing membrane subhyaline except for infuscated patch near apex of fore wing (Fig. 82).

Notes.

The holotype of T. alishana fits better with T. alticola than with T. taihorina considering its sculpture. The male holotype has been collected at the same day and locality as the male holotype of T. alticola .

Distribution.

China (*Ningxia, *Shaanxi, Taiwan). Collected at 1236-1800 m.
