A new genus of minute stingless bees (Meliponini: Hypotrigonina) is described from Southeast Asia. Ebaiotrigona Engel & Nguyen, gen. nov., is based on the type species Lisotrigonacarpenteri Engel, recorded from Vietnam, Thailand, Laos, Cambodia, and southern China. The species was previously considered an enigmatic member of Lisotrigona Moure, but is removed to a new genus based on its unique male terminalia that differs considerably from that of Lisotrigona and instead shares resemblances with Austroplebeia Moure, and the presence of yellow maculation (also similar to that of Austroplebeia). It is possible that Ebaiotrigona is the extant sister group of Austroplebeia, but this requires confirmation by future phylogenetic analyses. Based on available biological observations, Ebaiotrigonacarpenteri could not be confirmed as lachryphagous as is well documented from the tear-drinking species of Lisotrigona and Pariotrigona Moure.
