Diagnosis.
Large species, on average largest of those treated here. Body colouration yellowish brown to ochreous. Wing pattern dark brown, with proximal three anterior spots reduced. Male terminalia with ventral gonostylus large; rostral spines moderate in length, slightly curved. Wing length 6.8–9.6 mm.
Description. Male
. Head. Antenna brown, short, not extending to anterior margin of prescutum. Flagellomeres mostly short-ovoid, with longest verticils subequal in length to their respective segments.
Thorax generally yellowish brown to ochreous, with whitish pruinosity. Pronotum yellowish brown, considerably darkened medially. Prescutum with median area darkened, brown. Pleuron somewhat paler than dorsal parts of thorax. Wing (
Fig. 8
) tinged with yellow. Wing pattern dark brown; proximal three anterior spots reduced: spot 1 indiscernible, spot 2 restricted to dot at Sc2 not reaching anteriorly beyond Sc, spot 3 considerably reduced, sometimes falling into two dots, one at base of Rs, other at tip of Sc1. Spot 4 (pterostigma) distinct and of normal extent. Distinct, moderately broad seam along outer cord, including distal section of Cu. Another seam along distal margin of discal cell. No seam along proximal section of Cu (proximal to m-cu). Apex of wing slightly infuscated. Sc1 without macrotrichia. In contrast to other species, veins intensively darkened on sections covered with wing pattern. Wing venation with discal cell rather long, proximal section of M1+2 (anterior margin of discal cell) mostly longer than distal section. Tip of A2 beyond Sc2. Legs with tips of femora dark brown, sometimes almost black. Halter with knob moderately infuscated. Tarsi with tarsal claws slightly longer than half length of tarsomeres 5 (
Fig. 7
).
Abdomen yellowish brown, distal segments darker. Male terminalia (
Fig. 1
): Tergite 9 with shallow median emargination at posterior margin. Gonocoxite comparatively short, about half length of ventral gonostylus. The latter ovoid, comparatively large, about 1.3 times as long as broad, only slightly enlarged medially in proximal part, with rostral prolongation short, directed more or less medially. Rostral spines short to moderate in length, slightly curved and slightly darkened, distinctly longer than rostrum from base of more distal spine to apex.

Ƥ (collector not given, possibly M. Goetghebuer) (
ISNB
). In 1974, Br. Theowald kindly sent to me the two specimens above, when the
type
series of
D. (D.) luteipennis
was on loan with him from
ISNB
. At that time, I made a drawing of the male terminalia from the
holotype
. Insufficient material and insufficient experience, however, prevented me from recognizing
D. (D.) fuscinota
sp. n.
as a separate species.

Nomenclatural note.
There are two different original spellings of
D. (D.) luteipennis
:
luteipennis
on p.
108 in
the species heading and on p.
109 in
the legend for
Fig. 1
, and
lutripennis
on p.
109 in
the legend for
Fig. 4
(
Goetghebuer & Tonnoir 1920
). Although
lutripennis
may be implicitly considered an inadvertent error, there is no explicit evidence of this in the original publication (
ICZN
, Article 32.5.1.), and, hence,
luteipennis
is fixed here as the correct original spelling (
ICZN
, Article 32.2.1.).
Discussion.
The wing pattern in
D. (D.) luteipennis
is rather peculiar, as regards both its restricted extent and considerable intensity. On a distinctly yellow wing membrane, a dark brown seam along the outer cord is the most conspicuous mark (
Fig. 8
). This full-coloured condition is however not the case for most of the specimens, many of which are more or less teneral. In the structure of the male terminalia,
D. (D.) luteipennis
most resembles
D. (D.) magninota
sp. n.
and
D. (D.) pallidinota
sp. n.
in having a large and broad ventral gonostylus (cf.
Figs 1 and 3–4
), differing from them in the details specified in the discussions of the respective species.
Distribution.
Dicranomyia (Dicranomyia) luteipennis
was recorded from the following countries:
Belgium
,
Bulgaria
,
Czech Republic
,
France
(incl.
Corsica
),
Germany
,
Italy
,
Macedonia
,
Poland
,
Romania
,
Slovakia
,
Switzerland
;
Lebanon
,
Syria
(
Oosterbroek 2009
). The respective specimens from
Bulgaria
,
Czech Republic
and
Slovakia
(
Starý 1974
,
1979
,
Krzemiński & Starý 1989
) all were identified by me and belong to
D. (D.) fuscinota
sp. n.
, as does the material from
Switzerland
(
Geiger 1985
,
1986b
,
Podenas
et al.
2006
) (see Material examined of
fuscinota
sp. n.
). The single specimen from
Poland
(
Krzemiński 1991
) proved to be
D. (D.) chorea
(see Appendix). The record from
Corsica
(
Podenas
et al.
1997
) is based on specimens of
D. (D.) pallidinota
sp. n.
, as are the records from
Lebanon
and
Syria
(
Starý & Freidberg 2007
) (see Material examined of
pallidinota
sp. n.
). The record from
Germany
by
Mendl (1972)
is represented by
D. (D.) chorea
(see Appendix), as apparently is that by
Mendl (1977)
(the specimens not examined but with collection date
14.–24.v.1976
not probable for
luteipennis
, nor
fuscinota
sp. n.
). Another record from
Germany
(
Reusch & Bellstedt 2001
, based on
Rapp 1942
) could not be checked, as could not be the records from
France
(Thomas 1977), that from
Italy
by
Hartig (1971)
[other Italian material recorded by
Starý & Oosterbroek (1996)
pertains to
fuscinota
sp. n.
; see Material examined of
fuscinota
sp. n.
], from
Macedonia
(
Simova 1959
) and
Romania
(
Erhan-Dincă 1984
). Thus, at present,
D. (D.) luteipennis
is reliably only known from
Belgium
,
Czech Republic
and
Slovakia
, with questionable records from
Germany
,
Italy
,
Macedonia
and
Romania
.
