Abstract
The type material of eight species of Empididae described by R. Frey in his 1935 paper referring to the Swedish Kamchatka Expedition 1920–1922 of René Malaise are revised: E. (Anacrostichus) pachymorion Frey, E. (A.) vicaria Frey, Empis (Polyblepharis) kamtchatica Frey, E. ( Pachymeria) sjoestedti Frey, Hilara galactoptera Frey, H. ragasides Frey, Rhamphomyia (Pararhamphomyia) albibasis Frey; R. (Ctenempis) malaisei Frey. The lectotype is designated for the following species: Empis (Anacrostichus) pachymorion Frey, 1935; E. (A.) vicaria Frey, 1935; Empis (Pachymeria) sjoestedti Frey, 1935; Hilara ragasides Frey, 1935; Rhamphomyia (Pararhamphomyia) albibasis Frey, 1935; Rhamphomyia (Ctenempis) malaisei Frey, 1935. Six valid species are re-described: Empis (Anacrostichus) pachymorion Frey; E. (Polyblepharis) sjoestedti Frey; Hilara lactescens Frey (= H. galactoptera Frey); H. ragasides Frey; Rhamphomyia (Pararhamphomyia) albibasis Frey; R. (Ctenempis) malaisei Frey.
