A new genus and species of Collembola in the family lsotomidae are described from Michigan: Micranurophorus musci n. g., n. sp. A redescription of Cryptopygus exilis (Gisin) (= Isotomina exilis Gisin) is also given, based on specimens from Michigan. The new genus is characterized by the lack of a furcula and by abdominal chaetotaxy similar to Isotomodes. It is related to Pseudanurophorus.
