''Baeomorpha'' is an extinct genus of baeomorphid

parasitic wasp Parasitoid wasps are a large group of hymenopteran superfamilies, with all but the wood wasps ( Orussoidea) being in the wasp-waisted Apocrita. As parasitoids, they lay their eggs on or in the bodies of other arthropods, sooner or later causi ...

Taxonomy

In the initial 1937 description, Brues placed the genus within the

Scelionidae The hymenopteran family Scelionidae is a very large cosmopolitan group (over 3000 described species in some 176 genera) of exclusively parasitoid wasps, mostly small (0.5–10 mm), often black, often highly sculptured, with (typically) elbow ...
