Plain Language Summary
This paper treats an interesting fossil species from Cretaceous Burmese amber that extends the known distribution of the family of parasitic wasps it belongs in. It nicely links previous fossils from Canadian and Russian amber deposits to existing species of the family that now occur only in the southern hemisphere, thus showing that the family was probably once worldwide in distribution. The paper is important because the geographic location of this fossil contradicts a previous theory hypothesizing that the family originated in the northern hemisphere.
