Diagnosis. The new subspecies differs externally from the typical specimens of
D. turana
by the darker fuscous-grey colouration and the more obsolescent pattern. Head, thorax and forewings are rather uniformly dark brownish grey, without ochreous shine. The reniform and orbicular stigmata and the subterminal line are marked with lighter grey scales. The crosslines are marked at the costa with diffuse blackish spots, the cilia are chequered with light grey and blackish scales. The abdomen and the basal part of the hindwings are whitish-grey. The specimens are on average slightly larger than the typical
D. turana
:
37–38 mm
(males),
40 mm
(female).
The male genitalia (
Figs 55–57
) show the taxonomically most important traits. Valvae are longer than those of
D. forficula
and are only gradually tapering distally, i.e. they have neary parallel margins. Clasper acute, slightly falcate, corona consists of 12–14 setae. Vesica is projecting ventrally, without subbasal diverticulum and cornutus, strongly saccate, not recurved helicoidally.

D. turana cisiliensis

Female genitalia (
Fig. 74
). Antrum broad U-shaped, more strongly sclerotised than in the related species; appendix bursae is strongly saccate and much shorter than corpus bursae.
Etymology. The name refers to the region near to the Ili river in
Kazakhstan
.
Note. A further, slightly darker greyish brown and larger male specimen (
41 mm
) was found in the Püngeler collection (
MNB
) with the labels:
“renigera var. turana
m
v. Tancré 2/1900” (hand written with black ink), “Asia centr.
(Issykul)
1894” (printed). It shows the external and genital traits of this subspecies, and it can be geographically allied to this subspecies. Unfortunately, due to the deficient data we desist to consider it as a
Paratype
of this taxon.
Bionomics and distribution. The new subspecies occurs in semi-desertlike submontane areas near to the border of the Djambul and
Almaty
regions of
Kazakhstan
; the moths are on the wing in a relatively early saison (from early June to the end of June).

designation.
The
male specimen, figured by
BANG-HAAS (1922
,
Taf.
XVII: 9) was dissected by
Boursin
(
Slide No. Boursin
MB360
) and is designat- ed here as
Lectotype
(
Fig. 29
). The female with the same label data was dissected by Fibiger (slide No. MF2508) and is treated here as
Paralectotype
(
Fig. 30
).
Diagnosis. The taxon
Agrotis (Lycophotia) renigera
var.
furiosa
Bang-Haas, 1912
was also misidentified until yet, listing as a synonym of
D. forficula
(see, for instance,
http://ftp.funet.fi/ index/Tree_of_life/insecta/lepidoptera/ditrysia/noctuoidea/noctuidae/noctuinae/dichagyris/#8847
). According to the short original description the forewings have a violet-reddish colouration with some rosy shade and with prominent pattern. The transverse lines are marked with deep black spots at the costa and the hindwings are blackish grey, with darker marginal area. The underside of wings is nearly evenly blackish grey, the hindwings are sligthly lighter. Wingspan
37–42 mm
, females slightly larger.
This description can be completed with the following diagnostic traits: the shape of the forewing is more elongate and acute apically than in the related
D. forficula
and
D. turana
, the reddish colouration of the forewings is densely irrorated with blackish-brown scales and the course of the crosslines are more oblique than in
D. turana
.

No.: Boursin MB360m
Male genitalia (
Figs 58
,
59
). Valvae are longer and broader than in
D. forficula
, costa below the cucullus is slightly tapering only, clasper is more elongate and straight than in
D. forficula
and
D. turana
. Aedeagus is relatively thick and short, vesica is tubular, not recurved helicoidally, however it has a short triangular subbasal diverticulum armed with a thin and relatively long needle-shaped cornutus.
Female genitalia (
Figs 75, 76
). The sclerotisation of the antrum is relatively weak and V-shaped. Appendix bursae is much shorter and more saccate than the corpus bursae but less saccate than in
D. turana
.
Distribution. The nominotypical subspecies of
D. furiosa
seems to be localised to a relatively restricted area in
Tajikistan
. The recently collected specimens from “
Tajikistan
, Khodshent reg. Mogoltau, 16-
17.05.1996
, leg. Lukhtanov” (coll.
PG
) can also be considered as representatives of the typical subspecies while the specimens from an other mountain system of the Tien- Shan range in Kirghisia belong to a new subspecies, described below.
