Diagnosis.
The species has some characters in common with the
D. stylata
group: The vertex displays (in dark specimens) an intermediate transverse row of markings (similar to
D. stylata
), the aedeagus (
Figs 41G, H
) is smooth, distad narrowing with apical hook, and provided with a basal shield. The hind margin of the female pregenital sternite (
Fig. 34I
) is straight or at most slightly convex. The connective is slightly longer than in
D. stylata
, its branched portion distinctly longer than the basal one, the bifurcation rather narrow. The pygofer displays about 3–4 macrosetae in its dorso-caudal portion. The styles (
Fig. 41I
), however, are not geniculate, but equally curved with acuminate tooth at mid-length and equally narrowing apical portion. The long, apically rounded genital plates (
Figs 41K, L
), which protrude beyond the pygofer apex, form an exclusive character.
Distribution (
Figs 57
,
62B
).
We studied specimens from
Austria
and
Germany
. In addition, there are records for
Czech Republic
(
Lauterer, 1984
),
Poland
(
Dworakowska, 1968
), and
Slovakia
(
Lauterer, 1984
). The record in Metcalf for
the Netherlands
, based on
Reclaire (1944)
is erroneous. Reclaire’s record refers to
Germany
. The species is recorded by
Servadei (1967)
in
Italy
from
Apulia
,
Basilicata
, and
Calabria
. We found specimens (
1 male
,
2 females
) from
Apulia
and
Basilicata
, inserted in his collection as
D. horvathi
. These specimens belong to
D
.
butzele
. The specimens from M. Manfriana (
Calabria
, Monte Pollino) could not be examined. In view of the apparently restricted distribution of
D. horvathi
in Central Europe with records only from
Germany
,
Austria
,
Poland
,
Czech Republic
and
Slovakia
, the presence of
D. horvathi
in southern
Italy
is extremely doubtful.
Ecology.
Helictotrichon pratense
is recorded as host plant (
Nickel, 2003
).
