Hymenolepis horrida (Cestoda: Hymenolepididae) and Catenotaenia peromysci (Cestoda: Anoplocephalidae) in Voles from the Canadian Rockies

Cestodes from Clethrionomys gapperi (n ¼ 34) and Microtus longicaudus (n ¼ 8) from Kootenay National Park, British Columbia, Canada are reported. Two species of cestodes, Hymenolepis horrida (sensu lato) and Catenotae- nia peromysci, were found in Clethrionomys gapperi, and 1 species of cestode, H. horrida, was found in Microtus longicaudus. Clethrionomys gapperi represents a new host record for C. peromysci. The Canadian Rockies is a new locality record for both cestode species.
