Summary: | 2. Pegomya atricauda Ringdahl, 1944 Figs. 8–12. ‘ Pegomyia maculata Stein’; Stein 1906: 53, 88 (in part); Stein 1916: 125 (in part). Misidentifications. Pegomyia atricauda Ringdahl 1944: 16; Ringdahl 1959: 243, 252. ‘ Pegomya maculata Stein’; Chandler 1998: 168 (in part). Misidentification. Pegomya atricauda Ringdahl; Hennig 1973 a: 527, text-figs. 455, 456, plate-figs. 772, 886 and 925; Michelsen 2004 (Finland, Sweden). Description. Male. Very similar to P. maculata but different as follows: Legs overall darker: All femora fuscous brown, or mid and hind femora fuscous yellow on basal three-quarters; tibiae fuscous brown to fuscous yellow. Short genal setae fewer, uni-serial. Sternite V (Fig. 8) and hypopygium (Figs. 9, 10) only in subtle details different from other species of the P. maculata species group. Gonites (Fig. 11): Postgonite strongly angled backwards on distal half, but without a rounded notch at posterior margin as in P. macrophthalma (Fig. 17). Phallus (Fig. 12): Posterior hump of basiphallus prominent, arising immediately below epiphallus; distiphallus convex at hind surface. Female. Not identified. Material examined. FINLAND: Karelia australis (Ka): Vehkalahti, 2 males 12.vii. 1969 (L. Tiensuu) [FMNH]. GREAT BRITAIN: ENGLAND: Herefordshire: Devereux Pool, male paralectotype of Pegomyia maculata Stein, 3.vi. 1898 (J.H. Wood) [NMS]; SCOTLAND: Inverness: Loch Garten, 1 male 24.vi. 1963 (E.C.M d’Assis-Fonseca) [BMNH]. SWEDEN: Småland (SM): Bolmen, male holotype of Pegomyia atricauda Ringdahl, 27.vi. 1943 (O. Ringdahl) [MZLU]. Torne Lappmark (TO): Abisko, 360m, Ridonjira mouth, 1 male 4.viii. 2001 (D.M. Ackland) [OUMNH]. Distribution. Previously only known with certainty by the male holotype from Sweden: Småland (Ringdahl 1948), as the present study has shown that subsequent records from Finland (Hackman 1976; Hackman & Meinander 1979) and Denmark (Michelsen 2004) are based on misidentifications of P. maculata and P. macrophthalma , respectively. However, other material confirms the occurrence of P. atricauda in Finland and northern Sweden. British records from England and Scotland are also new, as it has previously, e.g. by Chandler (1998), been mixed up with P. m a c u l a t a . : Published as part of Michelsen, Verner & Ackland, Michael, 2009, The Pegomya maculata species group (Diptera Anthomyiidae) in Europe, with description of a new species, pp. 51-65 in Zootaxa 2315 on page 57, DOI: 10.5281/zenodo.275413 : {"references": ["Ringdahl, O.
