The world genera of the Bobekia-group of Alysiini (Braconidae: Alysiinae) are reviewed and keyed. A new genus (Neodiasta gen. nov.) is proposed for Phasmidiasta ecuadorensis Fischer, 2006, from Ecuador. One new subgenus (Parabobekoides subg. nov.; type species Separatatus (Parabobekoides) yinshani sp. nov. from NW China) is described and illustrated. Neosymphanes Belokobylskij, 1998 is a new synonym of Bobekia Niezabitowski, 1910 (syn. nov.).
