A total of 205 tardigrades representing two orders, five families, nine genera and ten species were extracted from a moss sample (104 tardigrades) and a lichen sample (101 tardigrades) collected near Missoula, Montana, in 2016. Three of the species are new to Montana and one is new to science, Platicrista loloensis nov. sp., which is distinguished by its smooth cuticle, the presence of internal cuticular bars at the base of the claws of legs II and III and a median cuticular bar between the claws of leg IV. Keywords: tardigrade; distribution; Montana; new species. [p. 3: ] "The species of tardigrades recovered were not uniformly distributed among the two samples representing two different types of habitats (Table 1). All three members of the family Hypsibiidae were found only in the moss. Three of five Macrobiotidae species were also found only in the moss. Mesobiotus harmsworthi sensu lato, known for its intercontinental distribution, was recovered from both the moss and lichen samples. Milnesium and Ramazzottius were found only in the lichen sample. No pattern of association among the species and their habitats can be determined with only two samples."
