aRecently found in high -elevation Andean forests (Ramsay et al. 2021); detailed data lacking.
bQuestioned with a High Arctic record (Calloway et al. 2011); taxonomic affinity of the Canadian species is uncertain (P. Gąsiorek and R.M. Kristensen, personal observations). cStec et al. (2022) noticed that the Macrobiotus ariekammensis complex occurs in Arctic and alpine habitats (all known records came from Palaearctic mountains). However,the record of M. adelges, now considered a synonym (probably incorrectly) of M.ariekammensis, came from the Pieniny Mts (Dastych 1988). This mountain range is well known for its relatively mild climatic conditions and, consequently,that is why several tardigrade species known for their xerothermic preferences can be found so far north (e.g. Cornechiniscus cornutus, Parechiniscus chitonides). Thus, the complex was not included in the table given its ecogeographic status is unclear.
