Ergebn. der Exped. Filchner nach China und Tibet 1903-05, Vol. 10, 1: 214 . Type Locality: Not specified; fixed by Allen (1938:544) as "...from the Tsingling [mountains] in the vicinity of Sianfu [Xian]." [ China ]. Vernacular Names: Tsing-Ling Pika . Synonyms: Ochotona (Ochotona) syrinx Thomas 1911 ; Ochotona (Ochotona) xunhuaensis Shou and Feng 1984 . Distribution: In the mountains of C China , including Shaanxi , Gansu , Qinghai and Sichuan provinces. Conservation: IUCN – Endangered as O. thibetana huangensis . Discussion: Subgenus Ochotona . Formerly considered a subspecies of thibetana ( Allen, 1938 ; Ellerman and Morrison-Scott, 1955 ; Feng and Zheng, 1985 ; Smith et al., 1990). Yu and Zheng (1992 b ) first suggested full species status for huangensis , based on differing morphology, and later ( Yu et al., 1997 , 2000) supported this with molecular studies. O. huangensis appears to be broadly sympatric with O. thibetana , but largely allopatric in distribution with O. cansus and O. thomasi .
