Description.
Male.
Very similar to
P. maculata
but different as follows: Fore femur fuscous brown, only narrowly fuscous yellow on anterior surface and near apex; mid and hind femora and all tibiae fuscous yellow to yellow, only “knees” of middle and hind legs more or less darkened, fuscous brown. Short genal setae fewer, uni-serial. Sternite V (
Figs. 13, 14
) almost as in
P. maculata
except membranous flap distally on posterior lobes apparently better demarcated from sclerotized part. Hypopygium (
Figs. 15, 16
) scarcely different. Gonites (
Fig. 17
): Postgonite strongly angled backwards on distal half, at mid-length with a deep, rounded notch at posterior margin. Phallus (
Fig. 18
): Posterior hump of basiphallus very prominent, separated from epiphallus; distiphallus nearly straight at hind surface.
Female.
Not identified.

Distribution.
Previously only known by the male
holotype
from
USA
: North Carolina (
Griffiths 1984
). Thus all European records given above from
Austria
,
Denmark
,
Great Britain
(
England
,
Scotland
) and
Sweden
are new. The species has in
Great Britain
been mixed up with
Pegomya maculata
(e.g., Chandler 1998) and in
Denmark
misidentified as
P. atricauda
(e.g.,
Petersen 2001
).
