Taxonomic remarks.
Schnabl
in
Schnabl & Dziedzicki (1911)
described
brunneonigra
from one male and one female collected in
Poland
: Ż wir (Warsaw area)
5 May 1909
on flowering
Salix caprea
. The
syntypes
were probably lost during WW2, yet the excellent original illustrations of the male terminalia, including a photomicrograph of sternite V, leave no doubt about the identity of the male
syntype
.
The small, dark-coloured male is easily confused with the common
P. intersecta
but unmistakable by the shape of posterior lobes of sternite V. The female was previously unrecognized, but a reliable difference from the otherwise very similar female of
P. intersecta
may be seen in the narrower parafacials, a character that also applies to males.
Description.
Small (WL 3.4–4.3mm; n=29), overall very reminiscent of
P. intersecta
but differing as follows:
Male.
Parafacial linear, distinctly narrower than basal width of fore tibia. Pair of interfrontal setulae normally absent. Sternite V (
Figs. 65, 66
) very different: long upraised posterior lobes with bare angular lamella strongly expanded meso-distally but apically not extended beyond articulation of digitiform appendage. Hypopygium (
Figs. 67, 68
): cerci less convex and surstyli less subapically expanded in lateral aspect.
Female.
Body covered in darker grey dusting that becomes olive grey on dorsum of thorax and abdomen. Parafacial narrower, in middle barely as wide as basal width of fore tibia.
Material examined.

Distribution.
Apparently a widespread species in the boreal and elevated parts of the Holarctic Region, but easily confused with the common
P. intersecta
occurring in the same areas. It is known with certainty from Europe (
Michelsen 2004
),
Japan
(
Suwa 1974
) and North
America
(
Griffiths 1987
), but some females agreeing well with
P. brunneonigra
have presently been seen from Kashmir (
India
) at the northern border of the Oriental Region.
