Diagnosis.
This large species, generally with distinct green or blue tinge in the coloration of its fore wings, is distinguished by proportionally long legs and a strongly protruding ovipositor (
Fig. 8
). In its male genital morphology, it resembles
D. stylata
, but never shows spinules on the ventral side of the aedeagus (
Fig. 10M
). The nymphs display no particular pattern of markings (
Fig. 9I
), in contrast to both
D. exilis
and
D. stylata
.
Distribution (
Figs 55A
,
56
,
57
).
In
Italy
we collected the species in
Friuli-Venezia Giulia
,
Emilia-Romagna
and
Basilicata
. Servadei records it also from
Piedmont
and
Veneto
. Some specimens in his collection were misidentified and belong to
D. stylata
. The species has never been recorded from
Sardinia
or
Sicily
.
D. impudica
is widely distributed in Europe and the East Palearctic region to
Kazakhstan
,
Uzbekistan
, and
Kyrgyzstan
(
Nast, 1972
).
We studied specimens from
Albania
,
Bulgaria
,
Czech Republic
,
Germany
,
Greece
,
Hungary
,
Italy
,
Romania
,
Slovakia
,
Spain
,
Turkey
,
Ukraine
.
In addition, there are records for
Austria
(
Holzinger, 2009
);
Belarus
(
Borodin, 2004
);
Bosnia and Herzegovina
(
Horváth, 1903b
);
Denmark
(
Ossiannilsson, 1983
);
Estonia
(
Söderman
et al.
, 2009
);
France
(
Ribaut, 1952
);
Finland
(
Albrecht
et al.
, 2015
);
Great Britain
(
Le Quesne, 1969
);
Kazakhstan
(

);
Kyrgyzstan
(
Dubovsky & Turgunov, 1971
);
Latvia
(

);
Lithuania
(
Vilbaste, 1974
);
Moldova
(
Nast, 1987
);
Poland
(
Dworakowska, 1968
);
Russia
: European part (
Emeljanov, 1964
);
Serbia
(
Janković, 1966
);
Sweden
(
Ossiannilsson, 1983
);
Turkey
: Central part (
Horváth, 1903b
), Eastern Part (
Koçak & Kemal, 2012
);
Uzbekistan
(
Dubovsky, 1966
). The record supposed by
Metcalf (1967)
to concern
the Netherlands
(
Reclaire, 1944
) actually refers to
Germany
.
Remarks.
Ribaut (1952)
writes that the aedeagus of
D. impudica
, in contrast to
D. stylata
, is “dépourvu de carènes latérales à la base”, means that it lacks a shield-shaped base.
Ossiannilsson (1983)
does not mention this character, but gives two figures of the aedeagus in lateral view: one for a specimen from
Poland
, which apparently has no lateral carina, and another one from
Sweden
, which is figured also in ventral view, and which displays a carina, even if it is not very distinct. The material we examined from different regions in Europe (but not from
France
and Fennoscandia), displays generally a distinct basal shield (including specimens from the coast of the Baltic Sea in North
Germany
). Apparently, this character is rather variable, and possibly the populations from western and northern Europe are different in this character in respect of the populations in southern, southeastern and eastern Europe.
Taxonomic remarks.
D. ivanovi
Kusnezov, 1928a
has been recorded from Central European
Russia
, Southern European
Russia
,
Ukraine
(
Nast, 1972
). Until now, there were apparently no figures of this species, and the description given by the author gives no information about the genital morphology. In his description of
D. lukjanovitshi
,
Kusnezov (1929)
indicates the position of the new taxon near
D. ivanovi
and
D. stylata
. This was the only hint to an affinity of
D. ivanovi
to the
D. stylata
group. The examination of
syntypes
of
D. ivanovi
(
Figs 8C, D
;
10Q
;
11I
;
12I
) showed no essential differences to
D. impudica
. Therefore, we establish the synonymy of
D. ivanovi
with
D. impudica
.

Ecology.
In
Italy
the species was found on dry meadows, near the sand coast and above all on the ruderal grasses on the gravel of broad riverbeds at low altitude. On the Balkan Peninsula we collected specimens on dry meadows and steppic habitats. Host plants are
Calamagrostis epigejos
, in northern
Italy
also
Elymus athericus
(and perhaps other
Elymus
species
) (
Nickel, 2003
).
Phenology.
We collected the species from the beginning of June until the end of August.
Nickel (2003)
records the species (as monovoltine) until the end of September.
