Pseudodiphascon arrowsmithi, a New Species of Tardigrade from British Columbia, Canada (Macrobiotidae: Eutardigrada: Tardigrada)

Abstract

A new species of macrobiotid tardigrade was found on two mountains on Vancouver Island, British Columbia, during a study of the tardigrades on five mountains on the island. Pseudodiphascon arrowsmithi, n. sp., is distinguished from other species in the genus by its three large macroplacoids with the third as long as or longer than the first, the very large microplacoid and the presence of lunules.
