Two new peculiar mid-Cretaceous braconid genera, Megalyrhyssalus gen. nov. (type species Megalyrhyssalus clavicornis sp. nov.) and Stephanorhyssalus gen. nov. (type species Stephanorhyssalus longiscapus sp. nov.), are described and illustrated from Burmese amber. According to the particular morphology and wing venation of Megalyrhyssalus gen. nov. a new subfamily Megalyrhyssalinae subfam. nov. is created. The subfamily Seneciobraconinae is synonymised under Protorhyssalinae (syn. nov.). Additionally, a key to the genera of Braconidae having second recurrent vein (2m-cu) in forewing is provided.
