Item Fig wasps in Dominican amber (Hymenoptera, Agaonidae) ; American Museum novitates, no. 3541(New York, NY : American Museum of Natural History, 2006) Peñalver, Enrique.; Engel, Michael S.; Grimaldi, David A.The fauna of fig wasps (Hymenoptera: Chalcidoidea: Agaonidae: Agaoninae) preserved in early Miocene (Burdigalian) amber from the Dominican Republic is reported. Three species are described, representing both of the exclusively neotropical genera Tetrapus Mayr and Pegoscapus Cameron: Tetrapus delclosi Peñalver and Engel, new species, T. apopnus Peñalver and Engel, new species, and Pegoscapus peritus Peñalver and Engel, new species. All are described and figured based on females that are exquisitely preserved. The species are distinguished from each other as well as from modern relatives.Item A Miocene halictine bee from Rubielos de Mora Basin, Spain (Hymenoptera, Halictidae). American Museum novitates ; no. 3503(New York, NY : American Museum of Natural History, 2006) Engel, Michael S.; Peñalver, Enrique.A new species of halictine bee (Apoidea: Anthophila: Halictidae) is described and figured from laminated mudstones of early Miocene age from Rubielos de Mora Basin, Teruel, Spain. Halictus petrefactus, new species, is the first bee from these deposits to be formally described. The geological history of the Halictidae and of the bees as a whole is briefly reviewed.Item Two wasp families rare in the fossil record (Hymenoptera) : Perilampidae and Megaspilidae from the Miocene of Spain ; American Museum novitates, no. 3540(New York, NY : American Museum of Natural History, 2006) Peñalver, Enrique.; Engel, Michael S.Three new species of parasitoid wasp are described and figured from early Miocene (early Burdigalian) compression fossils from Rubielos de Mora Basin, Spain. These wasps are significant as they are representative of two families exceedingly rare in the fossil record. The first is a species of the family Perilampidae (Chalcidoidea) and, aside from an old and unconfirmed record of an undescribed Perilampus in Baltic amber, is the only documented fossil of this lineage. Perilampus renzii, new species, is described from a single female. The remaining two species are both of the family Megaspilidae (Ceraphronoidea), which is otherwise known in the fossil record solely from a paucity of species preserved in fossil resins. Conostigmus lazaros, new species, and C. chthonios, new species, are distinguished from each other as well as modern congeners.
