Basal Cyclorrhapha in Amber from the Cretaceous and Tertiary(Insecta: Diptera), and Their Relationships: Brachycera in Cretaceous Amber Part IX

Diverse new basal (aschizan) Cyclorrhapha fossilized in amber are described from the Tertiary and Cretaceous, and their relationships are examined with character-based phylogenetic hypotheses for each family or family group. There are 18 new species in 15 genera (11 of them new) and four families plus the Syrphoidea. Fossils are from the Early Cretaceous of Lebanon, Late Cretaceous of New Jersey (United States) and Alberta (Canada), Eocene of...
