Anthidium (Anthidium) sichuanense Wu, 1993

( Fig. 27 a–h, male, holotype)

Anthidium sichuanensis Wu, 1993: 1398 , ♂.

Anthidium (Anthidium) sichuanensis Wu, 1993 : Wu, 2006: 163, ♂ (redescription), Fig. 85. (incorrect publication as 1992).

Diagnosis: This species is known only from the male. The lateral lobe of S6 large and extending far beyond rest of apical margin, the median lobe of S6 with two strong projections distinguishes this species and the very similar A. (A.) flavotarsum Wu, 1982 . It can be distinguished from A. (A.) flavotarsum by the lateral lobe of S6 broad and blunt ( Fig. 27f ) and metasomal terga covered with dense pubescence ( Fig. 27e ).

Material examined: China, Sichuan: Wenchuan Xian, Yingxiu (31º24′N, 103º36′E), 900–1000 m, 1 ♂ (holo- type), 1.VIII.1983, leg. Xue-Zhong ZHANG ; Xiangcheng Xian, Zhongriwu (31º24′N, 103º36′E), 3800 m, 1 ♂ (paratype), 5.VII.1982, leg. Xue-Zhong ZHANG .

Type locality. China: Sichuan: Wenchuan Xian, Yingxiu .

Distribution: China (Sichuan).

Floral association: unknown.

Remarks: The holotype specimen was dissected, but the genitalia are lost; thankfully, Wu (1993, 2006) previously illustrated the main characters of the species. It is possible that A. sichuanense represents a melanic form of A. sikkimense Mavomoustakis which has similar T7 and S6, similar abundant long pubescence, and has very limited maculations on the terga.
