Hungary for his consistent guidance in Noctuidae
work. This present study was
supported by the ICAR- Network Project on Insect Biosystematics. We thank ICAR-Research Complex For NEH
Region, Sikkim for stay and Forest Environment and Wildlife Management
Department, Sikkim for essential arrangements. All type photographs are provided from
the Heterocera Ltd Database. The holotype
of O. elongata annamica is
deposited in the HNHM Budapest, the other specimens in the collection of G‡bor Ronkay (Heterocera
Ltd collection).
Knowledge
on the Noctuidae fauna of Himalayan and some adjacent
territories has been considerably increased from the early 1900s (Benedek et al. 2005).
Most of the Xyleninae and Orthosiini
fauna of the Himalayan region was explored and published by M. Hreblay & Laszlo Ronkay (B‡lint & Katona 2013), Owada (1993), Ronkay & Ronkay (2001), Benedek et al.
(2005), Ronkay et al. (2010), Benedek et al. (2012a,b) , Benedek et al. (2013), Saldaitis
et al. (2014), and Benedek & Saldaitis (2014). The Indian part of the Himalaya, however,
was least explored for Noctuidae in recent years
except for the inclusion of a few described species in major taxonomic
revisions. In the present study
under ICAR-Network Project on Insect Biosystematics a few explorations were
undertaken in parts of Sikkim and we report here new range records of the
Winter Moth Owadaglaea elongata
Hreblay & Ronkay,
1998.
The genus Owadaglaea was first
established by Hacker & Ronkay (1996) with type species Owadaglaea chloromixta
from India, Himachal Pradesh. Hreblay & Ronkay (1998)
provided the detailed characterizations and distribution patterns by describing
seven new species and discussed relationships within four species groups. Further, Ronkay
& Ronkay (2000) reduced those four groups to the lucida, chloromixta and
barna species-groups. Recently, Benedek et al. (2012b) described four new species
from Himalayan region and provided a revised checklist of the genus with the
taxonomic placement of the new species. Hreblay & Ronkay (1999) described two subspecies, viz., Owadaglaea elongata ssp. siamica Hreblay & Ronkay, 1999 and O. e. ssp. annamica
Hreblay & Ronkay,
1999 from Thailand and Vietnam, respectively.
The
specimens included in the study were collected from parts of Sikkim, India, using
ultraviolet light traps. The
voucher material is deposited at the National Pusa
Collection, Division of Entomology, Indian
Agricultural Research Institute (IARI), New Delhi, India (NPC). Nomenclature, male and female genitalia
studies were carried out as described by Ronkay &
Ronkay (2000) and Ronkay et
al. (2010). The abdomen was treated
in 10% KOH for 10 to 20 min at 900C using a Dry Block Heizgerat 2800.
Subsequently, genitalia were cleaned and stored in glycerol. For photographs, genitalia were placed
on a slide in glycerol with a cover slip.
Photographs were taken with a Leica DFC425C digital camera mounted on a
Leica M205FA stereozoom microscope with automontage.

Hacker & Ronkay
Owadaglaea elongata Hreblay & Ronkay 1998
Diagnosis: The closest species of Owadaglaea
elongata are O. yoshimotoi
and O. kulmani. O. elongata can be separated from O. kulmani by the larger size and the more light chocolate
brown-olive forewing pattern. The
male clasping apparatus of the three species is essentially similar, but O. elongata has narrower valva,
a differently curved ampulla and differently shaped cucullus. The female genitalia of the O. elongata has a basin shaped ostium, broader ductus and larger
cervix bursae mostly similar to O. kulmani.
Description (Images 1, 2, 3): Wingspan
33–36 mm, length of forewing 16–17 mm. Front collar striped brindle
with dark brown yellow and black hairs; tegulae
sandy-brown; mid thorax blackish-brown; antennae ciliate; forewings elongate
with pointed apex; ground color of males light shiny
cream color mixed with chocolate brown ground color on male with some olive, females similar but lighter;
subterminal area, costa, reniform
and frame of orbicular light sandy color; cilia
rather long, crenulate and dark brown on male and
females; hindwing oval, male blackish brown and dark
chocolate brown on female; discal spot poorly
visible; cilia short.
Male genitalia (Images 5, 6): Uncus
medium size, apically dilate; tegumen high; juxta large, bell-shaped; vinculum elongate, V-shaped with
thick shafts; valva elongate and narrow,
asymmetrical; cucullus pointed; corona reduced; sacculus asymmetrical, on the right side larger with longer
process; clavus large, thumb-shaped; harpe long, thick and also asymmetrical as left side is
slight longer and more curved downwards; basal shaft long, strongly sclerotized
running down to saccular plate on the ventral margin;
ampulla narrow, asymmetrical, connected with long but narrow basis to the harpe; aedeagus arched at middle,
carinal process weak; vesica
moderately broad with a two diverticulum and one small cornutus.
Female genitalia (Image 7): Ostium
triangular, basin shaped, ductus narrow and
sclerotized; cervix bursae large, conical and gently
ribbed; corpus bursae large, oval.
Material examined: Reg. no: NPC008, 1
male, 2 females, India, Sikkim, Gangtok,
1,650m, 27.32710N & 88.59550E, 21.xi.2013, coll. P.R.
Shashank.
Distribution: Nepal, India (Sikkim, Gangtok) (present study)
Remarks: The specimens collected from Sikkim
are slightly darker and olive in colour compared to type specimen. However,
there is no genitalia variation in these.
This may be due to variation in season or the effect of
environment. Two subspecies, O.
e. ssp. siamica Hreblay
& Ronkay, 1999 and O. e. ssp. annamica Hreblay & Ronkay, 1999, are different from typical O. elongata.
They differ in the wing ground colour, O. e.
ssp. siamica brightly white ocher is more clearly recognizable with elongate blurred
transverse lines that are evidently double and lighter. O. e. ssp.
annamica (Image 4) is blackish-brown. The underside of both
wings are monochrome chocolate-brown with indistinguishable drawings,
which clearly differ from the sharper drawing of O. e. ssp. siamica and O. elongata.
