Abstract. Opportunistic sightings of Aglais caschmirensis aesis were recorded for the first time (on two different occasions) from Dibrugarh city in the state of Assam with new elevation records (109 and 113 m) from the north-eastern region of India.

Key words: ; Dibrugarh; Jokai Reserve Forest; Northeast India; Tea Estate.

Resumen. Los avistamientos de Aglais caschmirensis aesis se realizaron por primera vez (en dos ocasiones diferentes) en la ciudad de Dibrugarh en el estado de Assam con nuevos registros de elevación (109 y 113 m) en la región noreste de la India.

North-eastern region of India comprises of Arunachal Pradesh, Assam, Manipur, Meghalaya, Mizoram, Nagaland, Sikkim, Tripura, and Northern parts of West Bengal (Choudhury 2004) and is one of the richest biodiversity zones of India which harbors around 64% of the total butterfly species reported from India (Joshi & Dhyani 2014). are important components of biodiversity and are ecologically important due to the role they play in the food chain of a forest ecosystem (Mac Nally & Fleishman 2004) and acts as a pollinator (Kunte 2000; Tiple et al. 2007), biological indicators (Tiple 2007; Sengupta 2021) of environmental variation and quality, and have significant conservation value (Sawchik et al. 2005). A change in their distribution and abundance may be an early warning towards changing habitat patterns, degradation of environmental qualities of that particular region or areas and ultimately towards alteration of climatic conditions (Mandal 2016). The total number of butterfly species observed from the Indian region is about 1,504 (Tiple et al. 2006), out of which about 962 species belonging to five families and sub families were described from Northeast India alone, which belongs to six families (Papilionidae, Pieridae, , Riodinidae, Nymphalidae and Hesperiidae) (Gupta & Shukla 1988; Joshi & Dhyani 2014). Research works on butterfly fauna of North Eastern region has been carried outby

The Indian Tortoiseshell

The Aglais Dalman, 1816 is represented by three species in India namely Indian Tortoiseshell Aglais caschmirensis (Kollar, 1844) is distributed from Jammu & to Himachal Pradesh, Uttarakhand to Arunachal Pradesh and Nagaland, the distribution of Ladakh Tortoiseshell Aglais ladakensis (Moore, 1878) ranges from Jammu & Kashmir to Sikkim and Mountain Tortoiseshell Aglais rizana (Moore, 1872) is distributed along Jammu & Kashmir to Sikkim (Varshney & Smetacek 2015). In India, the species Aglais caschmirensis (Kollar, 1844) is represented by two subspecies; Aglais caschmirensis caschmirensis (Kollar, 1844) which is a western subspecies known from the Kashmir Valley to Kulu (Himachal Pradesh) (Varshney & Smetacek 2015) and Aglais caschmirensis aesis (Fruhstorfer, 1912) distributed through Uttarakhand to eastern and Northeastern India (Kehimkar 2008; Varshney & Smetacek 2015). In the North-eastern region A. c. aesis has been reported from Arunachal Pradesh (Greeshma 2010; Sondhi & Kunte 2016), Manipur (Irungbam et al. 2017), Meghalaya (Imam & Kharkongor 2019), Nagaland (Naro 2012), Sikkim (Chettri et al. 2018) and Northern parts of West Bengal (Roy et al. 2012).

Observation and significance

On January 11, 2021 at 1145 h, a single individual of A. c. aesis (Fig. 1) was recorded from Jalan Tea Estate (27.4843°N 94.9321°E; elev. 109 m) at Dibrugarh, Assam, India. The species was observed for around 6 minutes before it flew away. On February 20, 2021 at 1624 h, another individual was recorded from the Jokai Reserve Forest (27.3794°N, 94.9233°E; elev. 113 m) at Dibrugarh, Assam, India. The morphological characteristics were not recorded as the individuals were not captured and the identification of the species is done by photographic documentation followed by cross checking in Evans (1932) and Kehimkar (2008). These observations of A. c. aesis from the state of Assam, in the north-eastern region of India, confirm the presence of this species in the state and thus provide the first photographic evidence of A. c. aesis from Assam, India (Fig. 2). According to published literature (Fig. 3), A. c. aesis is restricted to an elevation range of 209-2546 m in the North- eastern region. This observation of A. c. aesis also indicates an unusual low elevation record (which is 109 m) form Assam and thus from the north-eastern region of India.
