NHRS. 1&amp;female;, " <i>Dolerus</i> v. <i>toto</i> [sic!] n. var. Paratypus &amp;female; Malaise det. [written by R. Forsius?]", " <i>Dolerus yukonensis</i> Norton M.Heidemaa det.", MZAT (coll. Forsius). <i>Dolerus yukonensis</i> has a Holarctic distribution, and both red-banded/-marked as well as melanic color forms occur. According to Goulet (1986) the color forms developed independently in the coastal areas of both continents. This speaks against the subspecific status of the melanic color forms suggested by Benson (1959). According to Benson (1934a) <i>D. scoticus</i> Cameron can be distinguished from melanic forms of <i>D. yukonensis</i> by the strongly developed temporal furrows, like in <i>D. junci</i> and <i>D. incisus</i>, which are absent in <i>D. yukonensis</i>. He also wrote that " <i>Dolerus totus</i> Malaise, 1931, from Kamtchatka may be the same species as <i>D. scoticus</i> Cam." Benson (1934b) synonymized them (and <i>D. arcticola</i> Kiaer, 1898) with <i>D. scoticus</i> and later all of them with <i>D. yukonensis</i> (Benson 1958: corrigenda). Latterly, he regarded <i>D. scoticus</i> as a subspecies of <i>D. yukonensis</i> (Benson 1959) and reported it from Switzerland (Benson 1961) and southern Norway, Hallingskarvet District (Benson 1966). However, Benson was not aware of the presence of melanic forms of <i>D. incisus</i> and <i>D. subarcticus</i> in Norway, the males of which can most reliably be identified by their penis valves (Fig. 20C, D). The sculpture of the abdominal terga in <i>D. yukonensis</i>, as in <i>D. subarcticus</i>, is not as stable as is often assumed. The depth of the clypeus emargination and the lateral postocellar furrows also vary. However, no potential male of <i>D. scoticus</i>, which could support its status as a distinct species as proposed by Haris (2000), has so far been recognized. The lectotype female of <i>D. scoticus</i> probably belongs to <i>D. yukonensis</i>, and certainly not to <i>D. junci</i> or <i>D. incisus</i>. Here we retain the synonymy of <i>D. scoticus</i> with <i>D. yukonensis</i> proposed by Benson (1958) and concurred with by Goulet (1986), but admit that more DNA sequence data are needed to test the taxonomic status of the melanic forms, which show at least some coinciding structural differences. We have studied melanic and red-marked color forms from the Palaearctic, but only red-marked forms from the Nearctic.
