 Gynacantha chaplini  Khan, 2021


Abstract
 Gynacantha chaplini sp. nov. is described based on a male collected from the north-eastern region of Bangladesh. Distinguishing features of the adult male are illustrated and discussed. Gynacantha chaplini sp. nov. is distinguished from its congeners by a dark brown trapezium-shaped mark on the postfrons. An updated key is provided to identify the males of the Gynacantha species known from South Asia (Bangladesh, Bhutan, India, Nepal, Pakistan, Sri Lanka).

Key words: Anisoptera, taxonomy, conservation, diversity and distribution, South Asia
