Introduction Belle Vue, near Virton, 22. VIII. 2010, 1 ? on a leaf of , det., leg., coli. In August, September and October 2010 three J. Mortelmans Diptera species were found new to the Belgian fauna: Tephritis divisa Rondani, 1871 (Tephri­ Discussion tidae), Conops ceriaeformis Meigen 1824 (Conopidae) and Salticella fasciata Meigen 1830 Tephritis divisa is a species which can easily (Sciomyzidae). be confused with T. separata and T. mutabilis, but differs from these species by slight Detailed account of the findings differences in the aculeus and wing marking (Ku t u k , 2005 ; M e r z , 1994 ; S m it , 2010). All Tephritis divisa Rondani, 1871 (Tephritidae) specimens collected in this study were found Oostende, achterhaven : (1) 4.

Mortelmans distribution, occurring in most south European Salticella fasciata Meigen, 1830 (Sciomyzidae) countries (S m it , 2010). From neighboring (1) Oostende, duinen Raversijde, 22.

The absence in 2010, lo" on Senecio inaequidens, det., leg., central Europe can be due to the fact this species coll. J.
