Lastly, two species belonging to families incertae sedis, both in Burmese amber: Tethepomyiidae (Tethepomyia zigrasi Grimaldi & Arillo sp. , whose closest relatives are from the Late Jurassic of Kazachstan, the Late Cretaceous of New Jersey, and Recent of California). ) Apystomyiidae (Hilarimorphites burmanica Grimaldi & Cumming, sp. n., stem-group species of the family, both in Burmese amber) Apsilocephalidae or near (therevoid family-group) (Kumaromyia burmitica Grimaldi & Hauser, gen. and Microburmyia veanalvena Grimaldi & Cumming, sp. n., in Burmese amber, the only definitive species of the family from the Cretaceous) Mythicomyiidae (Microburmyia analvena Grimaldi & Cumming gen. and Burmacyrtus rusmithi Grimaldi & Hauser gen.

Taxa are as follows, with significance as noted: In Stratiomyomorpha: Stratiomyidae (Cretaceogaster pygmaeus Teskey, Lysistrata emerita Grimaldi & Arillo, gen. They are preserved in amber from the Early Cretaceous (Neocomian) of Lebanon, Albian of northern Spain, upper Albian to lower Cenomanian of northern Myanmar, and Late Cretaceous of New Jersey USA (Turonian) and Alberta, Canada (Campanian). Hauser, MartinĪbstract Thirteen species of basal Brachycera (11 described as new) are reported, belonging to nine families and three infraorders.

Within the family Mesoraphidiidae, Necroraphidia arcuata gen. n., from the Peñacerrada I outcrop (Moraza, Burgos), is the first amber inclusion belonging to the family and described from western Eurasia, thus substantially expanding the paleogeographical range of the family formerly known from the Cretaceous of Brazil and eastern Asia.

The new fossils provide additional information on early ant diversity and relationships and demonstrate that the monophyly of the Sphecomyrminae, as currently defined, is still weakly supported. after two workers remarkably preserved in a single piece of Early Cenomanian French amber. The genus Sphecomyrmodes, hitherto known by a single species from Burmese amber, is also reported and a new species described as S. The diagnosis of the tribe Haidomyrmecini is emended based on the new type material, which includes a gyne (alate female) and two incomplete workers. In this paper, a new sphecomyrmine ant, allied to the Burmese amber genus Haidomyrmex, is described from mid- Cretaceous amber of France as Haidomyrmodes mammuthus gen. Therefore, each new discovery of a Mesozoic ant is of high interest for improving our understanding of their early history and basal relationships. However, the latter is of major importance for ant relationships, as it is considered the most basal subfamily. Recent studies on the ant phylogeny are mainly based on the molecular analyses of extant subfamilies and do not include the extinct, only Cretaceous subfamily Sphecomyrminae.
