Abstract
Burmese amber continues to provide a plethora of unexpected fossils, with its extraordinarily rich and speciose mid-Cretaceous fauna of Arthropoda and particularly of Hymenoptera (Ross, 2015; Rasnitsyn et al., 2017; Li et al., 2018; Rasnitsyn and Öhm-Kühnle, 2018a, b; Zhang et al., 2018a–d). Among these specimens, there are abundant, minute and specialized wasps of the superfamily Serphitoidea, the wasp described in the present paper, in which characters of both Serphitidae and Archaeoserphitidae appear.
