F. coeruleogrisea ( Hammer, 1938)

– Isotoma coeruleo-griseus Hammer, 1938a: 43

– Folsomia alpha Grow & Christiansen, 1976: 616

– Folsomia alpha Christiansen & Tucker, 1977: 371

– Isotomina gracilis Stach, 1962: 11

AK Hurd & Lindquist 1958; Christiansen & Tucker 1977 as alpha ; Christiansen & Bellinger 1980, 1998 as alpha ; Danks 1981; Skidmore 1995 as coeruleogriseus, alpha and gracilis ; Potapov & Babenko 2000 as alpha ; Potapov 2001 as alpha ; Babenko & Fjellberg 2006

NU Hammer 1953; Christiansen & Bellinger 1980, 1998; Danks 1981; Fjellberg 1986, 1994 as alpha ; Skidmore 1995 as coeruleogriseus and gracilis ; Babenko & Fjellberg 2006

Remarks: It is extremely likely that all of these Nearctic records belong to a single species originally described from Eastern Greenland, although Hammer’s types have not been re-evaluated. The separate status of the uncoloured European form ( F. janstachi Potapov & Babenko, 2000 = gracilis ) probably also needs further support. General distribution: Nearctic, Eastern Palaearctic and Greenland.
