A Revision of the Scandinavian Tachydromiinae (Dipt., Empididae) described by J. W. Zetterstedt By MILAN CHVÁLA Katedra Syst. Zool., Charles University, Vinicná 7, Prague 2, Czechoslovakia Abstract J. W. Zetterstedt described between I8I9-I850 thirty-seven species of the Empidid subfamily Tachydromiinae in combination with Tachydromia Meig. (30), Tachypeza Meig. (5), Drapetis Meig. (I) and Empis L. (I). A revision of these species has been based on a study of Zetterstedt's Collec- tion at Lund, Sweden. Lectotypes or holotypes for thirty-six of Zet- terstedt's species are designated and a further two lectotypes for Platypalpus pallipes (Fall., I8I5) and Platypalpus boreoalpinus Frey, I943 have been selected. Five species are redescribed, viz., Platypalpus brevicornis (Zett., I842) � the male sex is described for the first time � , Crossopalpus curvinervis (Zett., I842), comb.nov., Platypalpus sordidus (Zett., I838), Platypalpus unguiculaws (Zett., I838) and Platypalpus boreoalpinus Frey, I943. The following species are described as new: Platypal pus confiformis sp.n., Platypalpus zetter- stedti sp.n., and Platypalpus alpinus sp.n. Some new synonymy is established: Symball- ophthalmus scapularis Collin, I96I is a synonym of Symballophthalmus fuscitarsis (Zett., I859), Tachydromia gilvipes Coquillett, I900 and Platy- palpus xanthopodus Melander, I928 are synonyms of Platypalpus unguiculatus (Zett., I838), Platy- palpus
