Abstract: Lilac Silverline Apharitis lilacinus
is a butterfly native to southern, northeastern,
& northern India and northern Myanmar. In northeastern
India it was known from a single record: H. Stevens from N. Lakhimpur, Assam in
1925. Four individuals were photographed on 15 May 2018 in D’Ering
Wildlife Sanctuary, Arunachal Pradesh, which is the first record of the species
after more than 90 years in northeastern India and
the first record from Arunachal Pradesh. The species was again recorded on 22
June 2020 from Dibru-Saikhowa National Park, Assam.
The aerial distance between both records was 36.5 km. This species is legally
protected under Schedule II, Wildlife (Protection) Act, 1972.
Keywords: Arunachal Pradesh, Assam,

Apharitis ranges from southwestern Sahara
(Afrotropical) to the northeastern Himalaya
(Indo-Malayan). There are 11 species in total with three reported in India. Apharitis was previously placed under Cigaritis and Spindasis.
It is different from Aphnaeus in having 11
veins instead of 12 (unlike Cigaritis and Spindasis). Lobe to hindwing not very marked in Apharitis, whereas in Cigaritis
there is no lobe to hindwing, and lobe well developed in Spindasis.
The species of this genus can be separated readily from Cigaritis
by the shape of the wing, and from Spindasis
by the coloration (Riley 1925).
Lilac Silverline Apharitis lilacinus
belongs to the blues butterfly family, measuring 32–36 mm. This group is called
Silverline because brilliant and faded silver lines run through the red bands
of the butterfly. The species is endemic to India and Myanmar. In northeastern India, the species was previously known from
North Lakhimpur, Assam based on a single record by H. Stevens (Riley 1925)
which is the only record of the species in northeastern
India. On 15 May 2018, one male and three females were photographed from D’ering Wildlife Sanctuary, Arunachal Pradesh (27.925N,
95.435E) (Image 1, 2). Two years later, another female was recorded from Dibru Saikhowa National Park,
located at Tinsukia & Dibrugarh district of Assam (27.606N, 95.361E) on 22
June 2020 (Image 3, 4). The aerial distance between the two records is 36.5 km.
The specimens from northeastern India appear to have
darker pigmentation than those from southern India.
The habitat of A. lilacinus is medium height mostly Impereta
cylindrica in D’ering
Wildlife Sanctuary, Arunachal Pradesh and Vivtiveria
sp., Saccrum spontaenium
in Dibru-Saikhowa National Park, Assam whereas the
other Spindasis sp. in northeastern India, prefer woodland/forest habitats. The
species is possibly not rare in a few localities of D’Ering
Wildlife Sanctuary and Dibru-Saikhowa National Park.
British North Lakhimpur covers the present Lakhimpur, Dibrugarh, Dhemaji and Tinsukia district, so the exact record of the
species by H. Stevens could not be ascertained and it could be within Dibru Saikhowa National Park.
This species is legally protected under Schedule II, Wildlife (Protection) Act,
1972.
The species is presently known to
occur from Hessarghata Lake, Benguluru,
where it was photographed for first time in 2012 (https://www.ifoundbutterflies.org/sp/2125/Apharitis-lilacinus).
It was also reported from Agastya Campus, Andhra Pradesh (unpublished data)
& Kumbhalgarh Wildlife Sanctuary, Rajasthan (Sundar et al. 2020) (Figure 1), however the paper wrongly
mentions the record from North Lakhimpur as Uttar Pradesh instead of Assam.
Other than these, there are no present known record of the species in India.
Historically, the species was
known to occur in Mhow, Madhya Pradesh after it was
described in 1884 (Swinhoe 1887); Malda,
West Bengal (de Nicéville 1890). Also known from
Mysore, Karnataka; Kasaul, Himachal Pradesh; Hardwar,
Uttarkhand, (N Lakhimpur) Assam (Riley 1925) and from
Coorg, Karnataka (Yates 1931). The species is known from Assam based on lone
record of the butterfly in North Lakhimpur by H Stevens (Riley 1925; Evans
1932), the only record of the species in northeastern
India (Figure 1).
The species is also known to
occur in Myanmar and possibly in northern Thailand (De Abera
1986), however no recent record is available from either of these countries.
Also, there is no specific locality of the species mentioned by De Abera 1986 in northern Thailand (Ek-Amnuay
2012). Hence, the species occurring in northern Thailand is doubtful.
Although the species is
historically known from many locations in India, the record from North
Lakhimpur, Assam (Riley 1925) is the lone record of the species in northeastern India. Our records from D’ering
Wildlife Sanctuary, Arunachal Pradesh in May, 2018 and Dibru-Saikhowa
National Park, Assam in June, 2020 confirms the existence of the species in northeastern India and first record of the species after
more than 90 years in the region. The record of the species from D’Ering Wildlife Sanctuary, Arunachal Pradesh is also the
first record of the species from Arunachal Pradesh and the record of the
species from Dibru-Saikhowa National Park of Assam is
the second record of the species from Assam since the record of H. Stevens from
North Lakhimpur (Riley 1925). On both the occasions, the species was recorded
in grassland habitats of D’Ering Wildlife Sanctuary
and Dibru-Saikhowa National Park respectively, which emphasis the importance of grassland habitat in Brahmaputra
floodplains for butterflies and other invertebrates. The species was not
recorded in the unprotected grassland habitat in Brahmaputra floodplain lying
adjacent to D’Ering Wildlife Sanctuary or Dibru-Saikhowa National Park, suggesting that the species
might not occur in non-protected grasslands and the butterfly probably prefer
medium height grasses with no cattle grazing in protected areas of Brahmaputra
floodplains.
