Distribution of the Firefly Genus Pteroptyx Olivier and a New Record of Pteroptyx asymmetria Ballantyne (Coleoptera: Lampyridae: Luciolinae) in Thailand

Abstract The unique congregating synchronous flashing firefly genus Pteroptyx Olivier has long provided economic benefits for many Southeast Asian countries as an ecotourism icon. Seventeen species of Pteroptyx have been identified to date. However, a survey of species diversity and distribution of this genus has never been thoroughly conducted in Thailand. During 2012–2015, several surveys were carried out to assess the species diversity and distribution throughout the mangrove and estuary areas in Thailand. Using both classical morphological examination and DNA data, four species of Pteroptyx were identified. In combination with Pteroptyx specimens examined from museum collections, we report herein the most recent assessment of species diversity and distribution of Pteroptyx in Thailand, with a new country record for Pteroptyx asymmetria Ballantyne. This study will complement and enhance the development of a firefly conservation plan for sustainable ecotourism in Thailand and other countries in the region.
