Two new species of Idris Foerster (Hymenoptera: Platygastridae) from Southeastern Brazil parasitoids of Argyrodes elevatus Walckenaer (Araneae:Theridiidae) and Scytodes sp. (Araneae: Scytodidae)

In this study two new species of IdrisFoerster (Platygastridae) are described and illustrated from specimens reared from eggs of the spider species ArgyrodeselevatusWalckenaer(Theridiidae) and Scytodessp. (Scytodidae) collected in Minas Gerais State, Brazil.Scytodidae is a new host family
