SPECIES Ochotona (Pika) argentata

Author:Howell, 1928.
Citation:Proc. Biol. Soc. Wash., 41: 116.
Common Name:Silver Pika
Type Locality:"15 miles [24 km] north-northwest of Ninghsia [Yinchuan], northern Kansu [Gansu, now Ningxia Auton. Reg.], China"
Distribution:Restricted to the Helan Shan range, Ningxia, China (Formozov, 1997; A. T. Smith et al., 1990).
Status:IUCN Critically Endangered (see Formozov, 1997; A. T. Smith et al., 1990).
Comments:Subgenus Pika. Formerly considered a subspecies of O. alpina (see comments therein). There is confusion as to whether argentata is the same as or different from O. helanshanensis. The two forms come from the same area, share similar pelage descriptions, and have similar body and skull measurements, thus appear to be synonyms (Formozov et al., In Press). See also O. pallasi.
