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°13′35.8′′ N & 92°06′78.8′′ 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
