Abstract

Palaearctic species of the genus Gymnophora are reviewed. Four new species, G. amurensis sp. n., G. gornostaevi sp. n., G. perpropinqua sp. n., and G. victoria sp. n., are described from the European Russia, Middle Asia, and Russian Far East. Females of two other species from the Far East are described under code letters. G. laciniata Michailovskaya, 1997 is synonymised under G. prescherweberae Disney, 1997. Lectotypes of G. arcuata (Meigen, 1839) and G. verrucata (Schmitz, 1929) are designated. The latter species is redescribed. Palaearctic females of G. nigripennis demonstrate wide variation of taxonomically important features and may, in fact, represent a group of closely related species. One female of G. nigripennis, which has been caught alive, is recorded to be infected with fungi.

Highlights

  • The genus Gymnophora Macquart, 1835 comprises more than 50 species recorded from the Holarctic and Oriental regions

  • European species are covered by Disney (1983, 1997), and Asian species have been treated by Brown (1987, 1988), Liu (1993), and Michailovskaya (1997). This genus is still poorly known in the Palaearctic Region

  • Japanese spe­ cies are satisfactory keyed and illustrated by Brown (1988), and we do not include them unless they are recorded from the mainland

Summary

INTRODUCTION

The genus Gymnophora Macquart, 1835 comprises more than 50 species recorded from the Holarctic and Oriental regions. European species are covered by Disney (1983, 1997), and Asian species have been treated by Brown (1987, 1988), Liu (1993), and Michailovskaya (1997). This genus is still poorly known in the Palaearctic Region. We are reviewing Palaearctic species of this genus, with special reference to the territory of Russia and allied countries. Biological data on Gymnophora are scarce and summarised recently by Brown (1998)
