Compression fossils of three genera and six species of Mymaridae (Hymenoptera: Chalcidoidea) are described from 46 million year old Kishenehn oil shales in Montana, USA.

Three new species of Gonatocerus are also described, G. greenwalti Huber, sp. n. , G. kootenai Huber, sp. n., and G. rasnitsyni Huber, sp.n. Previously described amber fossil genera are discussed and five genera in Baltic amber are tentatively recorded as fossils: Anagroidea, Camptoptera, Dorya, Eustochus, and Mimalaptus.
