9. Pegomya vittigera (Zetterstedt, 1838) (Figs 3, 4, 32, 41, 50, 59, 71) Anthomyza vittigera Zetterstedt, 1838: 697. Pegomya vittigera (Zetterstedt). Hennig 1973 c: 672, text figs 589‒591, table figs 755, 901, 981; Hackman 1976: 133; Hackman & Meinander 1979: 74; Michelsen 1985: 60. Pegomya ( Phoraea ) vittigera (Zetterstedt). Griffiths, 1983: 244, figs 314, 324, 336, 342‒ 345. For further synonymy and references, see Hennig (1973 c) and Griffiths (1983). Description. Different from P. zonata as follows: Size. Slightly larger, wing length up to 6.4mm. Male (Fig. 3). Basal part of antennal postpedicel bright yellow, concolorous with scape and pedicel, remaining part ochre brown to black. Palp yellow. Setation on postgena all black. Thorax extensively ochre yellow, only darkened along a median scutal stripe, on middle part of postnotum and on various smaller pleural areas. Mesonotum and legs with a distinct shine through thin whitish grey dusting. Legs yellow with darkened tarsi and small brownish black marks apico-dorsally on at least mid and hind femora. Abdomen extensively ochre yellow apart from narrow dark bands at hind margins of tergites I‒IV, covered in thin whitish grey dusting. Prealar seta same length as posterior notopleural seta. Wing vein C with a regular row of d setulae. Terminalia (Figs 32, 41, 50, 59): Cerci apically with some longish setae; other diagnostic characters are provided by the surstyli, gonites and phallus. Female (Fig. 4). Postpedicel yellow on about basal third, ochre brown to black on remaining part. Palp yellow. Ocellar triangle outside ocellar tubercle shiny, without any dusting. Setation on postgena all black. Thorax, legs and abdomen shining through thin cover of light grey dusting. Thorax wholly ochre yellow, or darker along a narrow median stripe on scutum. Legs yellow except for dark brown tarsi. Prealar seta same length as posterior notopleural seta. Wing vein C with a row of d setulae. Oviscapt (Fig. 71): Sternite VIII pieces with scattered fine setulae and sensilla on apical half; hypoproct less desclerotized, with a few fine discal setulae besides pair of apical setae; cerci slender, laterally convex, ending in pointed cutting edges.

Northern and central Europe from Britain and Fennoscandia in the north to North Italy in the south. Remarkably few records exist from outside Europe: “Ural” (Hennig 1973 c) and Kamchatka (Ringdahl 1930). NEARCTIC. Widely distributed in the boreal zone from Alaska across the continent to Quebec and New York (Griffiths 1983). Biology. In southern Finland (Hackman 1976, Hackman & Meinander 1979, Ståhls et al. 1989) reared from larvae in bolete sporocarps of the Leccinum scabrum species group (Boletaceae). In Canada reared from Leccinum sp. in Yukon Territory (Griffiths 1983). Bruns (1984) reared it in USA: Minnesota from Boletus edulis . : Published as part of Michelsen, Verner, 2015, Taxonomic review of the major larval pests of bolete fungi (Boletaceae) in Europe: The Pegomya fulgens, furva and tabida species groups (Diptera: Anthomyiidae), pp. 51-80 in Zootaxa 4020 (1) on pages 67-68, DOI: 10.11646/zootaxa.4020.1.2, http://zenodo.org/record/289621 : {"references": ["Zetterstedt, J.
