Based on intensive collecting from various sites in Sweden, the genus Dasyhelea Kieffer, 1911 was reviewed and the number of species now known from the country increased from five to twenty. Among the new species recorded there are two species described as new to science, D. dominiakae sp. nov. and D. gothlandica sp. nov., both in the subgenus Dicryptoscena Enderlein, 1936. The following subgenera are now documented from Sweden: Dasyhelea, Dicryptoscena, Pseudoculicoides Malloch, 1915, Prokempia Kieffer, 1913 and Sebessia Remm, 1979, the two latter subgenera being reported for the first time.
