Actinor Watson, 1893 is a monotypic genus
represented by Actinor radians (Moore,
1878). The species is distributed in
western Himalaya (from Kumaon in India to Chitral in
Pakistan) (Evans 1932). Moore (1878)
described the species from Dharmasala, Himachal
Pradesh under the genus Halpe Moore,
1878. Subsequently, the species
was reported from Mandi, Himachal Pradesh (Elwes
& Edwards 1897), Doon Valley (Mackinnon & de Nicéville
1898), Utzen Valley (Leslie & Evans 1903; Evans
1910), and Chitral in Pakistan (Evans 1912).
Singh & Bhandari (2003) included the species in the list of
Dehra-Dun valley following Mackinnon & de Nicéville
(1898). Kumar (2010) recorded the
species from Jharipani and Bhatta Phal Village of Mussoorie based on the collection of Zoological Survey of
India (ZSI) in 2003 and 2002 respectively; however, the authors did not provide
detailed information on the record of the species. Interestingly, this record has not been cited
in the list of butterflies from Garhwal, Uttarakhand
by Singh & Sondhi (2016), though Sondhi & Kunte (2018) do
mention the ZSI records. Recently, Tshikolovets & Pagès (2016)
reported the species from Kohala, Muzzafarabad,
Pakistan at an elevation range of 700–800 m.
Currently, this scarce species is known from Chitral to Uttarakhand
through Kashmir, Himachal Pradesh (Kangra, Kullu, Simla) and north Punjab
(Chandigarh) within an elevation range of 600–2,400 m (van Gasse
2017).
In one of our visits to Kalesar National Park (KNP), Haryana (Figure 1), we
encountered a single individual of A. radians (Image 1) at 21.04h
on 09 August 2019. We photographed the
species and later identified with the help of the description provided by Moore
(1878), Watson (1893), Elwes & Edwards (1897), Sondhi & Kunte (2018), and
the photograph available in www.ifoundbutterflies.org (Anonymous 2020). The species recorded from KNP is confirmed as
A. radians by the combination of the following characters: discal band of the forewing is irregular and continuous,
lower angle of the spots of the discal band continued
outward along the veins; three apical spots on forewing shifted in from the discal band; the post discal band
of the hindwing continuous from the vein 1b to 6, the medial band from the vein
1b passes across end cell upto vein 8, top most spot
between vein 7 and 8 of the hindwing shifted out from the medial band; a basal
spot present between upper border of the cell and vein 8 on the hindwing;
margin of the hindwing yellow; vein 2 of the hindwing nearer to the end cell
than the base of the wing; vein 3 of the hindwing originates immediately before
the end cell; vein 5 of the hindwing distinctly traceable; vein 7 of the
hindwing is close to end cell and originating at an acute angle; all the veins
and discal bands pale yellow; antennae with slender
club and sharp hook at the tip.
We recorded the species near a
perennial stream (30.314˚N & 77.564˚E) at an elevation of 345m,
approximately 70m downstream of Chand Sot dam in Tajewala,
southeastern part of KNP. The individual was observed perching on a
grass blade of Saccharum bengalense at a height of one meter above ground (Image
1). The bank of the stream at the
recorded site is mostly covered by Saccharum
bengalense, Parthenium hysterophorus
along with other shrubs and some broad leaf trees, bamboo at the edge
(Image 2).
Kalesar National Park is located in the
eastern part of Yamunanagar, Haryana, in the Shivalik range, south of Himalaya. The river Yamuna described the eastern
boundary of the park. The park is
primarily dominated by Sal and Khair forest with
scattered grassland.
The present record of Actinor radians from KNP is the lowest
distribution limit (elevation 345m). The
present record extend its range ca. 40km from nearest known location (Dehradun
Valley) as well as first report of the species from the state of Haryana. The species was not reported in earlier
studies by Sethy & Ray (2010) and Ranade (2017)
from KNP. With the present record the
number of butterflies of Kalesar National Park
increases to 40. This report highlights
the paucity of knowledge on faunal diversity especially lower taxa in the
region as well as importance of the last remaining forest at the extreme end of
the Terai Arc landscape.
