Clitellaria ephippium (Fabricius, 1775) (Diptera, Stratiomyidae) rediscovered in Norway. Norw. J. Entomol. 53, 21-22. The stratiomyid fly Clitellaria ephippium (Fabricius, 1775) is recorded from Norway for the first time since 1844. A single male was captured at Skoklefall in Nesodden municipality (AK) in 2005. The species is previously recorded once in Norway, from AK Oslo: Fjeldstuen.

E-mail: o.j.lonnve@nhm.uio.no The genus Clitellaria is characterized by a pair of strong lateral spines on the thorax in front of the wing-base (Rozkošný 1973) (Figs 1-2). The genus is represented in Europe with one species only; Clitellaria ephippium (Fabricius, 1775). The larva of C. ephippium is found in nests of the ant Lasius fuliginosus (Latreille, 1798) which occurs in hollow trees. The species is listed as VU (according to the IUCN criteria) in Sweden (Gärdenfors 2005), and is only known from a few localities. C. ephippium is distributed throughout Europe, but rare in the north. In addition to Norway and Sweden the species are reported from Austria, Belgium, Bulgaria, Croatia, Czech Republic, French mainland, Germany, Hungary, Italian mainland, Lithuania, Poland, Romania, central and south Russia, Slovakia, Slovenia, Spanish mainland, Switzerland, The Netherlands, and Ukraine (Pape 2006, Rozkošný 1983). According to Verrall (1909) the species is reported from Great Britain, but no specimens are available (Rozkošný 1983). C. ephippium has only been recorded once from Norway; AK Oslo: Fjeldstuen (EIS 18), 1 ♂, 1844, leg. Esmark (Siebke 1877, Rozkošný 1973, Falck & Greve 1990). The specimen is deposited in the entomological collection, Natural History Museum, University of Oslo. The species was considered extinct from Norway by Falck & Greve (1990). A single male (Figs 1-2) was captured in a yellow bucket-trap at AK Nesodden: Skoklefall (EIS 28, UTMWGS8432VNM935359) on 11 July 2005, leg. Ole J. Lønnve. The trap was situated in a moist bush-dominated ditch in a residential area at the edge of a pine forest. The specimen is deposited in the entomological collection, Natural History Museum, University of Oslo. REFERENCES Falck, M. & Greve, L. 1990.
