Item A new bethylid wasp in Lebanese early Cretaceous amber (Hymenoptera, Chrysidoidea), with comments on other Mesozoic taxa. (American Museum novitates, no. 3855)(American Museum of Natural History., 2016-04-07) Engel, Michael S.; Ortega-Blanco, Jaime.; Azevedo, C. O. (Celso O.)A new genus and species of bethylid wasps is described and figured from a female preserved in early Cretaceous (Barremian) amber from Lebanon. Holopsenella primotica, new genus and species, is distinguished from other bethylids and segregated into a new subfamily, Holopsenellinae, along with Cretabythus sibiricus Evans in late Cretaceous (Santonian) Taimyrian amber. Holopsenellines are perhaps basal within the family, representing a stem group to other Bethylidae, and, if so, those features shared with the coeval Lancepyrinae suggest a basal position for that lineage as well. In addition, Lancepyris alavaensis Ortega-Blanco and Engel in early Cretaceous (Albian) amber from northern Spain is considered generically distinct from the type species of the genus, L. opertus Azevedo and Azar in Lebanese amber, and is transferred to the new genus, Zophepyris, resulting in the new combination, Zophepyris alavaensis (Ortega-Blanco and Engel). The genus Archaepyris Evans, currently considered as incertae sedis within the family, is transferred to Lancepyrinae mostly because it shares the same groundplan traits with Lancepyris.Item A new lineage of enigmatic diaprioid wasps in Cretaceous amber (Hymenoptera, Diaprioidea). (American Museum novitates, no. 3771)(American Museum of Natural History., 2013-03-20) Engel, Michael S.; Ortega-Blanco, Jaime.; Soriano, Carmen, Dr., 1976-; Grimaldi, David A.; Martinez-Delclos, Xavier.A new family of microhymenopteran wasps is described and figured from three new species discovered in Cretaceous amber of Spain (Albian) and New Jersey (Turonian). Spathiopterygidae Engel and Ortega-Blanco, new family, is allied to the Diapriidae and Maamingidae (Proctotrupomorpha: Diaprioidea), sharing with these families putatively derived features relative to Monomachidae. The family contains three genera and three species, all new: Spathiopteryx alavarommopsis Engel and Ortega-Blanco, new genus and species, and Myamaropsis turolensis Engel and Ortega-Blanco, new genus and species, both from the early Cretaceous (Albian) of Spain, and Spathopria sayrevillensis Engel, Ortega-Blanco, and Grimaldi, new genus and species, from the late Cretaceous (Turonian) of New Jersey. Spathopria sayrevillensis is reconstructed using X-ray synchrotron microtomography. In addition, a peculiar new genus and species, Iberopria perialla Engel, Ortega-Blanco, and Delclòs, of stem-group Diapriidae is described from Spanish amber. The distinctive features and character combinations of these taxa are discussed in connection with possible relationships to the surviving lineages of diaprioids.
