Ochotona (Pika) collaris Nelson 1893

Ochotona (Pika) collaris Nelson 1893 , Proc. Biol. Soc. Wash., 8: 117.

Type Locality: "about 200 miles [322 km] south of Fort Yukon, Alaska near the head of the Tanana River." [ USA].

Vernacular Names: Collared Pika.

Distribution: WC Mackenzie, S Yukon, NW British Columbia ( Canada); SE Alaska ( USA).

Conservation: IUCN – Lower Risk (lc) ( MacDonald and Jones, 1987).

Discussion: Subgenus Pika . Broadbooks (1965) and Youngman (1975) considered collaris and princeps conspecific. Corbet (1978 c), following Argyropulo (1948) and Gureev (1964), included collaris in alpina . A statistical reevaluation of craniometric data by Weston (1981) indicated that collaris , princeps and alpina are separate species; Hall (1981:286) also recognized collaris as a distinct species. O. collaris and O. princeps share similar chromosome numbers that differ sharply from those of alpina and hyperborea ( Vorontsov and Ivanitskaya, 1973) , but are similar to pusilla ( Erbajeva, 1994) .
