Dolerus yukonensis NORTON, 1872

The recent Scottish specimens are at present considered to be a very dark North British form [possibly endemic] of D. yukonensis that initially was determined by Benson (1934) as Dolerus scoticus Cameron, 1881 . Some minor morphological as well as conspicuous colour differences exist between the Scots specimens and a long series of D. yukonensis collected by C. Kutzscher & A. Taeger in Finland (SDEI), det. Heidemaa. Goulet (1986) considered that black, coastal forms have been independently evolved throughout the Holarctic range of D. yukonensis . A revision of these taxa, including the closely similar D. cothurnatus , is being undertaken by M. Heidemaa (Tartu).
