Description.
Size.
Wing length up to 6.4mm.
Male
(
Fig.1
). A delicate, long-winged species with a small head and slender legs and abdomen. Body colour very variable, evidently growing darker by age. Antenna black except ochre-brown on distal part of pedicel. Palp ochre-yellow on basal third to basal half and black distally. Thorax dark, usually more or less translucent ochre-yellow on postpronotal callus and scutellum, covered in brownish grey to dark chocolate brown dusting. Wing and calypteres often intensely dark brown tinged. Legs ochre-yellow with brown tarsi, sometimes brownish infuscate on fore femur and distal parts of mid and hind femora. Abdomen ochreyellow to dark reddish brown, covered in light brownish grey dusting; median dark stripe practically absent. Longest aristal pubescence about 1.5 times as long as greatest basal diameter of arista. Head small, markedly wider than high. Parafrontalia extremely narrow, contiguous, at narrowest point separating eyes by much less than half width of anterior ocellus. Postgenal setation black. Proepimerals: 1 seta and 3‒5 setulae. Lower calypter same size as upper calypter and distinctly projecting behind it in lateral view. Terminalia (
Figs 11
,
16‒19
).
Female
(
Fig. 2
). Antenna black, more or less darkly reddish brown on scape and pedicel. Palp yellow on more than basal half, black on distal part. Thorax dark except ochre-yellow on postpronotal callus, prosternum and scutellum; covered in light bluish grey dusting. Legs, including tarsi, yellow to ochre-yellow. Abdomen ochre yellow to dark reddish brown, shiny through thin light grey dusting. Setation on postgena black except finest setulae yellow. Proepimerals: 1 seta and 2‒4 setulae. Oviscapt (
Figs 64, 65
) moderately long, about same length as preabdomen when fully extended. Sternite VIII pieces each with 1‒3 erratic setulae in front of 2‒3 hind marginal setae.

Type
material.
Meigen (1826)
described
Anthomyia fulgens
on male(s) from “hiesiger Gegend” and female(s) from “Hrn. von Winthem”. The only extant
type
specimen is a male in Meigen’s collection in
MNHNP
(under no.
2096 in
box 49) labelled “meigen / 2291 40”. It is without head, right mid leg, left hind leg and abdomen, a miserable state already mentioned by
Stein (1900a: 153)
. In order to fix the identity of the name
fulgens
I have labelled and designate herewith this ♂ as
lectotype
. It is a valid species of
Pegomya
as identified by
Stein (1906)
and subsequent authors.

Distribution.
PALEARCTIC. Widespread in northern and central Europe, ranging from
Iceland
and northern Fennoscandia to the Spanish Pyrenees and
Corsica
. Isolated East Asian records (
Hennig, 1973b
) from Irkutsk (
Russia
) and Harbin (
China
) are questionable and possibly refer to the closely related boreal and Holarctic
Pegomya transgressa
(see next species).
Biology.
In southern
Finland
(
Hackman 1976
,
Hackman & Meinander 1979
,
Ståhls
et al.
1989
) reared from larvae in sporocarps of the
Leccinum versipelle
and
L. scabrum
species groups (
Boletaceae
).
