Description. Very similar to P. zonata but different as follows: Size. Slightly larger on average; wing length up to 6.4mm. Male. As a rule more dark-colored, especially on thorax, mid and hind femora and on dorsal parts of abdomen. Setation on postgena all black. Hind femur ( Fig. 7 ) on basal two-thirds with a comb row of 7‒10 very short and spinulose pv setae. Terminalia ( Figs 30 , 39 , 48 , 57 ): Good diagnostic characters are found in the profile shape of the surstyli and the structure of the pregonites. Female. Scape and pedicel fuscous ochre brown to black; postpedicel black. Palp darkened on distal third or more. Setation of postgena all black. Thoracic pleura predominantly dark-coloured. Oviscapt ( Fig. 69 ): Sternite VIII pieces broader, with several sensilla on posterior part and some discal setulae; small hypoproct less desclerotized, with a few setulae in front of apical pair of setae; shape of cerci distinctive: slender, parallel-sided, ending in slightly projecting, obtusely rounded cutting edges.

Distribution. PALEARCTIC. Widespread in northern and central Europe, ranging from Iceland and northern Fennoscandia to the Spanish Pyrenees. Outside Europe recorded from Russia: Kamchatka ( Suwa et al. 2000 and above) and Japan ( Suwa 2005). NEARCTIC. Common and widespread across boreal and low arctic North America ( Griffiths 1983) and Greenland ( Griffiths 1983; Michelsen 2006b).

Biology. In Hungary ( Dely-Draskovits & Mihályi 1972) and southern Finland ( Hackman 1976, Hackman & Meinander 1979, Ståhls et al. 1989) reared from larvae in sporocarps of the Boletus edulis , Leccinum versipelle and L. scabrum species groups ( Boletaceae ). Also reared from Leccinum spp. in Finnish Lapland ( Ståhls et al. 1989). According to Hackman (1976), eggs deposited in clusters well beneath the cap surface belong probably to the present species. Also reared from Leccinum spp. in Yukon Territory and British Columbia ( Griffiths 1983). Bruns (1984) reared it from species of the Leccinum aurantiacum group in Minnesota.
