This document summarizes a study that recorded a new butterfly species, Euploea radamanthus radamanthus, in the Dudpukuria-Dhopachari wildlife sanctuary in Bangladesh. A total of 64 butterfly species from 7 families were recorded during the study period from October 2013 to June 2014. Euploea radamanthus radamanthus is newly documented as occurring in Bangladesh based on photographs taken of the species mud puddling in the sanctuary. This adds to the knowledge of butterfly diversity and distribution in Bangladesh.

Omar Shahadat, Tanvir Ahmed, Amit Kumer Neogi Abstract A study on butterfly diversity of Dudpukuria-Dhopachari wildlife sanctuary was carried out from October, 2013 to June, 2014. A total 64 species were recorded belonging 7 families and one species Euploea radamanthus radamanthus Fabricius, 1793 (Magpie Crow) under family Nymphalidae (order: Lepidoptera) was newly recorded in Bangladesh as distribution. The findings of the present study is to contribute and to update the butterfly checklist and is documented as new species as distribution in Bangladesh. Keywords: Butterfly, Magpie Crow, Nymphalidae, Lepidoptera, Bangladesh, Distribution. 1. Introduction Butterflies are generally regarded as one of the best taxonomically studies groups of insects [12] . Since early 18 century about 19,238 species of butterflies have been documented worldwide [7] . Studies on butterfly fauna are very few in Bangladesh. Very few studies on butterfly fauna in Bangladesh are well documented. Since 1947 very little research on butterflies has been conducted. According to Larsen only 311 butterfly species had been recorded from Bangladesh [10]. Neogi AK et al. has added 5 more new species to the checklist which takes the total number of butterflies to 316 [13]. Bangladesh for its rich natural properties has long been considered a realm of a number of butterfly species. But it is important to know the exact number of butterfly species that currently exist. Systematic data collections from all parts of the country are essential to compile the checklist to be updated about butterfly fauna of Bangladesh. In due course of an ongoing study on butterflies covering the core area of Dhopachari forest range under the Dudpukuria-Dhopachari wildlife sanctuary, a new butterfly species Euploea radamanthus radamanthus Fabricius, 1793 (Magpie Crow) was recorded for the first time in Bangladesh as distribution in the coordinate of 22属1335.8霞 N & 92属0678.8霞 E. According to Larsen, it should be in Srimangal forests and in the Chittagong hill tracks in Chittagong division [10]. 2. Materials and Methods The butterflies were recorded from the study area during the butterfly survey from October, 2013 to June, 2014. Butterflies were primarily identified directly in the field by capturing photographs (using Nikon D3200 with 70-300 mm lens). Few cases specimen were collected with sweep nets, placed in plastic bottle or plastic bag and carried to laboratory for further identification. Specimens were killed also by killing jar with chloroform and reserved in a plastic bottle. Sometimes specimens were caught for identification and then released without any harm. Collected butterflies were identified using field guides and following the identification key developed by Evans (1932) [5] . 3. Results & Discussion To protect the biodiversity, Dudpukuria-Dhopachari forest had been declared as a wildlife sanctuary in 2010 comprises a total area of 4,717 ha reserve evergreen and semi evergreen tropical forest. The sanctuary is situated along with a borderline of Chittagong, Rangamati and Bandarban districts at the foot of the Karnafuly and Sangu River. Most of parts of the Dudpukuria-Dhopachari wildlife sanctuary consists of Chittagong hills tracks area, is located
~ 23~ International Journal of Fauna and Biological Studies under Dudpukuria east and west Kurushia, west Dhopachari and single Dhopachari mouza. The wildlife sanctuary is located in kurushia range of Rangunia upazilla and dohazari range of Chandanaish upazilla. While surveying for the butterfly diversity, seasonality, availability of larval host plants, observed broad habitat types, ecological, behavioral observations, flight pattern and status of butterflies in the study area during October 2013 to June 2014 around Chittagong hill tracts and total 64 species were identified. The individual Euploea radamanthus radamanthus Fabricius, 1793 (Magpie Crow), was photographed at the time of mud puddling near the cow shed on 10th April, 2014. 9 species from Nymphalidae family has been recorded by previous study under the genus Euploea. Such as Euploea mulciber mulciber Cramer, 1777 (Striped Blue Crow), Euploea midamus rogenhoferi Felder & Felder, 1865 (Blue-Spotted Crow), Euploea klugii kiugii Moore, 1858 (Blue-king Crow), Euploea klugii kollari Felder & Felder, 1865 (Brown King-Crow), Euploea algae deione Westwood, 1848 (Long-Branded Blue Crow), Euploea core core Cramer, 1780 (Common Crow), Euploea crameri nicevillei Moore, 1890 (Sundarbans Crow), Euploea doubledayi doubledayi Felder & Felder, 1865 (Striped Black Crow), Euploea sylvester coreta Godart, 1819 (Double-Branded Crow). According to Larsen, Euploea radamanthus radamanthus Fabricius, 1793 (Magpie Crow) occurs widely in the Arakan and was common in Cachar. It should be both in the Srimangal forests and in the Chittagong Division [1, 2, 3, 10] . Wing span of Magpie Crow is: 80-90 mm. Geographical distribution: India, Bhutan, Myanmar, Sri Lanka, and Singapore. Morphological characteristics: Upper fore wings of male are velvety bluish black with pale blue sub-marginal spots. A pale blue brand present in 1b of upper fore wings. Large white patch present in discal area. Upper hind wings have few long, broad whitish streaks in basal to discal area. Some pale blue spots present in sub- marginal area of upper hind wings. Pale blue spots also present in sub-marginal areas of under hind wings and also white streaks present in basal to discal of under hind wings. Fig A: Dorsal view of E. radamanthus radamanthus during flying after mud puddling Fig B: Ventral view of E. radamanthus radamanthus during mud puddling 4. Conclusion These records decisively confirm the presence of Euploea radamanthus radamanthus Fabricius, 1793 (Magpie Crow), a new butterfly species for Bangladesh as distribution. This kind of finding is significantly important in updating the status and regional distribution of butterfly fauna of Bangladesh. 5.
