Proterosceliopsis

Proterosceliopsis is an extinct genus of platygastroid parasitic wasp, known from the Mid-Cretaceous of Eurasia. The genus was first described in 2014 from the Albian amber of the Escucha Formation.[1] In 2019 additional species were described from the Cenomanian-age Burmese amber, and was placed into the monotypic family Proterosceliopsidae.[2]

Taxonomy

In the initial 2014 description, the genus was placed in the Scelionidae.[1] However, traditional Scelionidae was found to be polyphyletic in a 2007 study,[3] which recovered a "main scelionid clade" as monophyletic. In the 2019 study describing the Burmese amber species, it was found to exhibit a unique combination of characters placing it outside both the modified Scelionidae and Platygastridae, thus causing it to be placed in a new family within Platygastroidea.[2]
