New records of scuttle flies (Diptera: Phoridae) from Iceland, with a survey of all simultaneously collected Dipteran families

During a visit to Iceland in 2001, 727 specimens of Phoridae were caught. Seven species of Phoridae were identified, five of whichwere recorded fromIceland for the first time: Megaselia coccyx Schmitz, 1965; M. humeralis (Zetterstedt, 1838); M. parnassia Disney, 1986; M. quadriseta (Schmitz, 1941) and M. tarsicia Schmitz, 1926. Themost abundant andmostwidespread phorid fly of the study wasMegaselia coccyx, ofwhich 510 specimens (70% of the catch) on 18 of 29 sampling sites were caught. The female of Triphleba renidens Schmitz, 1927 is given an improved diagnosis, and the abdominal sternite 7 is illustrated for the first time.With the results of this study a total of 11 species of Phoridae have been identified from Iceland. Four of them were also recorded from Greenland and 3 from the Faroe Islands. An overview of all other 36 families of Diptera (more than 48,394 specimens) obtained during the same excursion to Iceland is also presented.
