Material examined. Xizang ( XAAHU): 1♂, Nyingchi, Mêdog 80k, 2118 m, 9.vii.2018, leg. Pan Zhaohui ; 1♂, Bomi , Y’ong, 2211 m, 12.vii.2017, leg. Pan Zhaohui.

Diagnosis. The appearance of A. sinadmissa is very similar to A. extinctaria . The male genitalia of these species are also similar, with regards to characters of the uncus, gnathos, cucullus and dividing juxta. They can be distinguished by the following differences: the processes of the ampulla are much longer than in A. extinctaria , the basal part of the juxta is joined and not totally dividing as in A. extinctaria .

Distribution. China ( Hubei, Hunan, Gansu, Sichuan, Yunnan, Xizang).
