A new lineage of evaniiform wasps in Cretaceous amber from Myanmar (Hymenoptera: Evanioidea)

Evanioidea are distinctive parasitoid wasps with a comparatively rich fossil record extending to at least the Late Jurassic. Here we report a remarkable mid-Cretaceous species belonging to the clade Evaniiformes, exhibiting a mosaic of features characteristic of Evaniidae alongside traits more typical of plesiomorphic lineages outside of the evaniiforms. Antevania hirsuta gen. et sp. nov. is described and illustrated from a well-preserved female preserved in amber from Kachin, northern Myanmar. The genus is placed within the new family Antevaniidae fam. nov., and comparisons are provided with other living and fossil Evaniiformes, together with brief comments on its potential parasitoid biology.
