I. plumosus Bagnall, 1940

– Isotomurus plumosus Bagnall, 1940: 101

MB Porco et al. 2014

Remarks: The presence of this species in the Nearctic needs confirmation. It was originally described from Europe ( Great Britain) and the majority of its records are from that region ( Potapov 2001). Asiatic specimens (from Severnaya Zemlya and Chukotka) mentioned by Potapov (2001) and Babenko & Fjellberg (2006) obviously belong to a different, recently described species, viz. I. chaos Potapov & Babenko, 2011 , having a similar general appearance. The occurrence of I. chaos or closely related forms in the Nearctic appears to be more probable than true European I. plumosus . Porco et al. 2014 detected two cryptic genetic units (L1 and L2) within this morphological form, and so several species are probably involved.

General distribution: uncertain.
