Acknowledgments. Eliana Buenaventura, Sven Marotzke and Jenny Pohl, all from the Diptera View in CoL collection of the Berlin Muse-
um, helped to organise a loan of Athyroglossa specimens. Jenny Pohl in particular invested much time searching for a historical specimen of A. flaviventris . The Alexander Koenig Research Museum supported the collecting trip to Georgia. Tony Irwin (Norwich) and Wayne N. Mathis (Washington) read an earlier draft of this manuscript, corrected the English and gave valu- able hints.
