Burmagomphus asahinai sp. nov. (holotype ♂: Cambodia, Cardamom Mts., Koh Kong Province, Thma Bang District, 6 km SWof its centre, rapids at the Thma Bang River, 25 August 2011, RMNH) is described fromKohKong Province of Cambodia and Nakhon Nayok, Chiang Mai and Parchuap Khiri Khan Provinces of Thailand and is compared with its nearest congeners. While the mesepisternum pattern is closest to that of B. gratiosus Chao, 1954, the female head sculpture combines structures found separately in B. gratiosus and B. williamsoni Förster, 1914.A redescription of B. gratiosus, including the hitherto unknown male, is provided based on a pair from Guizhou Province, China. © 2012 Worldwide Dragonfly Association.
