Anthidium (Anthidium) pseudomontanum Niu & Zhu , sp. nov.

( Fig. 20 a–f, female)

Diagnosis: The new species is very similar to A. montanum Morawitz, 1865 , but the clypeal margin is apically straight and smooth, with two distinctly lateral tubercles ( Fig. 20c ); on the contrary, the clypeal apical margin of female A. montanum Morawitz, 1865 is coarsely serrate, but still nearly straight medially ( Fig. 13b , Fig. 13c ).

Description: Female. BL = 8.5–9.5 mm ( Fig. 20a ); head broader than long, HW: HL = 63: 57 ( Fig. 20b ); gena slightly broader than eye, GW: EW = 18: 13. Clypeus broader than long, apical margin of clypeus straight and smooth, with two distinctly lateral tubercles ( Fig. 20c ); mandible with six sharp teeth separated by acute notches, apical one longest ( Fig. 20d ); omaular carina absent; pronotal lobe rounded anteriorly; scutellum rounded posterolaterally, without tooth, not greatly overhanging metanotum and propodeum ( Fig. 20e ); propodeum without fovea behind spiracle; fore wing with two submarginal cells, cells nearly equal in length, second recurrent vein meets distal to second submarginal crossvein ( Fig. 20a ); arolia absent; metasomal terga without maculation ( Fig. 20f ). Integument black, except yellow on one small marking on vertex near apex of eye ( Fig. 20a ), dull brownish on tegula ( Fig. 20e ), dull blackish-brown on coxae, trochanters, femora and tibiae, reddish-brown on tarsi ( Fig. 20a ), slightly brownish on sterna. Fore wing hyaline, veins and stigma dark brownish ( Fig. 20a ). Pubescence on T1–T2 pale yellowish-white ( Fig. 20f ), T3 mainly covered with reddish-brown pubescence, but mixed some pale separated yellowish-white pubescence medially, T4–T6 covered with reddish-brown pubescence ( Fig. 20f ); lower part of face with long pale yellowish-white pubescence, mixed with some yellowish-brown pubescence ( Fig. 20c ); vertex, scutum, scutellum and mesepisternum covered with long pale yellowish-white pubescence ( Fig. 20a , Fig. 20b , Fig. 20e ); gena covered with long pale yellowish-white pubescence, mixed with some blackish pubescence ( Fig. 20a ); tarsi covered with reddish-brown hair, femora and tibiae covered with long pale yellowish hair; scopa golden.

Male, unknown.

Type material: Holotype, ♀, China, Xinjiang: Taxkorgan Tajik Zizhixian, Hongqilafu (36º55′N, 75º33′E), 4400–4600 m, 12.VIII.1989, leg. Xue-Zhong ZHANG; paratypes: 1 ♀, same label information as holotype, 1 ♀, 4500 m, 13.VIII.1989, another information as the holotype.

Distribution: China (Xinjiang).
