Ourapteryx dierli
Inoue, 1994
was described from central Nepal (Inoue 1994) with specimens collected during
June (holotype and paratypes of this species were collected on various dates in
vi.1973) between 2,500–2,600 m from central Nepal (Inoue 1994, 1995). Later, O. dierli
was recorded from western Nepal at 1,000 m on 25.vii.1996 (Stüning
2000). Recently, Sondhi et al. (2020) reported it
from Sarmoli village (23.v.2019; 2,200 m; 30.079oN
& 80.235oE) near Munsiari in Pithoragarh district of Kumaon
in Uttarakhand, India. Hence the known
distribution range of O. dierli was noted as
eastern Kumaon in Uttarakhand, India to western and
central Nepal (Sondhi et al. 2020).
During the course of surveys
carried out on insects infesting the western Himalayan oaks, the authors
recorded one individual of this species (Figure 1) in the Chakrata
hills. The individual was attracted to a CFL light on 08.vi.2020 at Kanesar Range Chowki (2,238 m;
30.714oN & 77.859oE; 20:31h; Temp: 17.8oC; RH 77%),
Chakrata Forest Division, Dehradun District of
Uttarakhand, India. The forest habitat around the site is 12/C1a Ban oak forest
(Champion & Seth 1968) with Quercus leucotrichophora
being the dominant tree species along with associates like Deodar Cedrus deodara, Moru Oak Q. floribunda, Horse Chestnut Aesculus indica,
Blue Pine Pinus wallichiana, Alder Alnus nepalensis, Rhododendron
arboretum, Bhamora Cornus
capiatata, Pyrus pashia,
and Dwarf Bamboo Arundinaria falcata. The
earlier record from Uttarakhand by Sondhi et al.
(2020) of this species was also in a similar forest habitat, altitude and
season (pre-monsoon), which suggests the preference by this species for
habitat, altitude, and season.
This finding further extends the
western most limit in the distribution range of this species in the Himalaya to
the Chakrata hills of Garhwal,
Uttarakhand, India. This site of record lies in the Jaunsar
region near the state of Himachal Pradesh
to its west, and is ~250 km from
the nearest known earlier record from Munsiari in Kumaon, India.
