First record of the family Scolebythidae (Hymenoptera) in mid-Cretaceous amber from Myanmar

•Two new genera and species of Scolebythidae are described from Burmese amber.•Cladistic analyses resolve the relationships of the new taxa.•Heightened diversity and disparity among Cretaceous Scolebythidae is supported.•New taxa help to fill in the mid-Cretaceous gap in the fossil record of the family.

Two new genera and species belonging to the family Scolebythidae are described from mid-Cretaceous amber of Myanmar, Cursoribythus silvestris and Siccibythus musculosus. These taxa are introduced into the current phylogenetic tree of the family, in order to analyze their relationships and observe their impacts on our understanding of the family. The implication of the findings (this is the first record of the family in the Cretaceous amber deposits of Myanmar) are discussed.
