Notes on the Palaearctic fauna of Renocera (Diptera, Sciomyzidae)

Abstract

After revision of diagnostic characters of Renocera (either non-genitalic or genitalic) a new identification key for Palaearctic species is offered. The key takes into account the variability of the number of orbital setae in R. striata. Genitalic characters are discussed. The authors find diagnostic use of the shape of surstyli more difficult and less reliable than the shape of sternites 5. As follows from rich examined material, all three species of Renocera have the same trans-Palaearctic distribution — they are restricted to the forest belt.
