Remarks: A possible species complex which can be confused with H. pallidus and the Hypsibius convergens - dujardini complexes ( Kaczmarek & Michalczyk 2009a). The distribution of Hypsibius microps sensu lato is largely Holarctic ( McInnes 1994a) but specimens of this group should be examined extremely carefully as they may represent new species.
