Abstract

Moss samples were collected from trees and rocks in Haida Gwaii, British Columbia, Canada, and examined for the presence of tardigrades. Specimens from 24 taxa were found in 17 out of the 22 examined samples. New species records for British Columbia are provided and undescribed Grevenius and Crenubiotus species were found; a division in four morphogroups of Grevenius, based on number and presence of placoids, is provided to aid in the future identification. In addition, three specimens of a new species belonging to a potential new undescribed Diploechiniscus species were identified. The finding of Macrobiotus occidentalis occidentalis also provides the occasion to transfer the latter one to the genus Diaforobiotus, for which a new dichotomous key for the identification of its species is given and to redefine the family Richtersiusidae. The DNA sequences of selected taxa are also provided. The high number of tardigrade species collected from a relatively low number of samples highlight how still unexplored is tardigrade diversity, particularly in still-largely insular island systems like Haida Gwaii.
