Anthidium (Proanthidium) qingtaoi Niu & Zhu , sp. nov.

Diagnosis: The new species can be distinguished from Anthidium kashgarense ( Cockerell, 1911) by the following combination: Male, anterior surface of F2 is reddish brown ( Fig. 39c ), projection on subapical inside of hind trochanter is sharp and long ( Fig. 39j ), gonostylus is narrow and acute apically ( Fig. 39i ); Female, lower part of genal area is black, without yellow marking ( Fig. 40a ), yellow band on vertex is narrow, sometimes interrupted medially ( Fig. 40f ); anterior surface of F3 is reddish-brown ( Fig. 40e ); the new species differs from Anthidium trochantericum in that the color of anterior surface of male F2 ( Fig. 39c ) and female F3 ( Fig. 40e ) is reddish-brown (black in A. trochantericum ).

Type material: Holotype, ♂, China, Xizan : Zanda Xian, (31º29′N, 79º47′E), 3680 m, 25.VII.2018, leg. Qing- Tao Wu ; Paratypes: 28 ♂, 23 ♀, same label information as the holotype, 3 ♂, 15.VIII.2019, leg. Qing-Tao Wu & Dan ZHANG; Zanda Xian , Xiangzi town, Xixie village (31º46′N, 79º30′E), 4023 m , 6 ♂, 1 ♀, 15.VIII.2019, leg. Qing- Tao WU & Dan ZHANG; Pulan Xian , Pulan Town, Chide village (30º17′N, 81º08′E), 3943 m , 1 ♂, 13.VIII.2019, leg. Qing-Tao WU & Dan ZHANG .

Distribution: China (Xizang).

Floral association: Melilotus officinalis (Fabaceae) .

Etymology: The specific name is dedicated to Mr. Qing-Tao WU who collected the holotype.

Remarks: If A. luteiventre Friese is a synonym of A. trochantericum as claimed by Zanden (1995), in addition to color differences presented in the diagnosis, A. qingtaoi differs from A. trochantericum in the longer spine of the hind trochanter based on study of the A. luteiventre type. Anthidium qingtaoi appears to be closely related to A. kvakicum Mavromoustakis from Tajikistan. Based on the description it appears to differ from A. kvakicum by reduced yellow markings including the absence of an L-shaped yellow stripe laterally and posteriorly on the scutum and the yellow marking of the vertex broadly interrupted. Unfortunately, no mention is made of the hind trochanter in the description.
