Extinct genus of insects
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. In 2019 additional species were described from the Cenomanian-age Burmese amber, and was placed into the monotypic family Proterosceliopsidae.
Taxonomy.
In the initial 2014 description, the genus was placed in the Scelionidae. However, traditional Scelionidae was found to be polyphyletic in a 2007 study, 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.
