Anthidium (s. str.) kryzanovskii -sic Wu, 1962: Wu, 2006: 157, ♀, ♂ (new description), fig. 78.

Diagnosis: Both sexes with the paraocular area maculated nearly to the top of the eye ( Figs 4b , 5b , 6b ); clypeus entirely yellow, without a black mark ( Figs 4b , 5b , 6b ); propodeum of female without a fovea behind the spiracle ( Figs 4f ); mandible of male with 3 teeth ( Fig. 5c ); male with apical margin of S3 strongly convex medially ( Fig. 5e ); S5 of male with black combs on the apicolateral projections ( Fig. 5f ); gonostylus of male pointed apically, not notched ( Figs 5g, 5h ).

Material examined: Yunnan, Chenggong Xian (24º54′N, 102º48′E) , 1 ♀, 20.IV.1940, leg. no information on label; Jinping Xian (22º42′N, 103º12′E), 900 m, 1 ♀, 27. V .1956, leg. Panfilov (holotype); Pu’er Xian (23º00′N, 101º00′E), 1400 m, 1 ♀, 4.IV.1955, leg. Kryzhanovsky (paratype); Pu’er Xian, Ximahe Wetland Park (22º48′N, 100º58′E), 1 ♀, 24.IV.2018, leg. Yong WANG ; Xishuangbanna, Damenglong (21º29′N, 100º30′E), 650 m, 1 ♀, 14.IV.1958, leg. Le-Yi ZHENG , 2 ♀, 13.IV.1994, leg. Huan-Li XU; Xishuangbanna, Menglun (21º54′N, 101º12′E), 580 m, 1 ♂, 30.III.1994, leg. Xiao-Lin CHEN ; Simao, Ximahe, Meizihu Park (22º45′N, 100º59′E), 1 ♂, 1.X.2007, leg. Rui ZHANG .

Floral association: Tephrosia hamiltoni (Fabaceae) , Blumea sp. (Asteraceae) , Tridex sp. ( Asteraceae ), Helianthus annuus (Asteraceae) , Eupatoreae sp. ( Asteraceae ).

Distribution: China (Yunnan); Burma ( Myanmar), India, Laos, Thailand, Cambodia.

Remarks: Female P. orientale vary in the number of mandibular teeth including individuals with five teeth and others with six. Number of teeth is apparently variable among at least some species of Pseudoanthidium . A specimen of P. orientale from Thailand has one mandible with five teeth and the other mandible with six. Long series of P. scapulare (Latreille) and P. stigmaticorne (Dours) reared from the same sites show variation in mandibular structure and the extent of facial maculations in females. Pseudoanthidium orientale also varies in markings with mark on frons present ( Fig. 4b ) or absent ( Fig. 6b ).

Examination of type material in the Insect Collection of the Institute of Zoology, Chinese Academy of Sciences, Beijing, China (IZCAS), revealed that information about the types of P. kryzhanovskii differs from that designated by Wu (1962); Wu (2006) misspelled the name as Anthidium (s. str.) kryzanovskii, and misidentified one female [Yunnan, Jingdong Xian (24º24′N, 100º48′E), 1 ♀, 2.V.1957, leg. Zeng-Hao ZHU] as this species, but compared with the holotype, the female belongs to the new species: Pseudoanthidium (Pseudoanthidium) yanruae . The attributes of the female from Chenggong Xian conform to the original description ( Bingham 1897), and differ from the description of Gupta (1993). Gupta (1993) described the female with yellow supraclypeal area and mandible with five teeth.
