A New Species of Hemilauxania Hennig (Lauxaniidae) from the Lower Eocene Oise Amber—The Oldest Record of Schizophora (Diptera)? †

SIMPLE SUMMARY: The first finding of a schizophoran fly in Oise amber (France) proved to belong to an extinct genus Hemilauxania Hennig, 1965 (Acalyptratae: Lauxaniidae), known previously only from Baltic amber (ca 48–34 Ma). It is described as a new species, H. parvula, and because it originates fr...

description SIMPLE SUMMARY: The first finding of a schizophoran fly in Oise amber (France) proved to belong to an extinct genus Hemilauxania Hennig, 1965 (Acalyptratae: Lauxaniidae), known previously only from Baltic amber (ca 48–34 Ma). It is described as a new species, H. parvula, and because it originates from the lower Eocene (about 53 Ma) it is apparently the oldest known representative of Acalyptratae as well as of Schizophora (Diptera). ABSTRACT: Hemilauxania parvula sp. nov., a new fossil species of the family Lauxaniidae (Diptera: Acalyptratae), is described and illustrated from Oise amber, France (Eocene, lower Ypresian, ca 53 Ma), and its relationship is discussed. Inasmuch as this first finding of a member of Schizophora in Oise amber probably represents the oldest known record of this group of Diptera, the age of Schizophora, based on the known fossil records, is discussed.
