Scale bars = mm. Megaselia exarcuata Schmitz, 1927 This species was omitted from the keys of Schmitz & Bayer (1965) in error, but was noted in a postscript on page 519. It will key out either at couplet 7 of Abteilung IV, Erste Reihe or on page 522 of Zweite Reihe. It is clearly close to M. gartensis Disney, but the latter consistently has a dark haltere knob, while M. exarcuata has a yellow to dark yellow knob. No specimens of the latter have been collected in the British Isles. It is possible that M. gartensis is merely a subspecies of M. exarcuata, but until more evidence is forthcoming the two segregates are being treated as sibhng species. Megaselia fennicola (Beyer, 1958) This species was described too late to be included in Schmitz's (1957) key to Abteilung II species. It is included in Colyer & Elberg's (1969) key to 'Plastophora' species, which are now included in Megaselia. As this latter key is not readily available, 1 note that males will run to couplet 30 in the key to British species (Disney, 1989a) and I illustrate the male hypopygium in Fig. Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original British Entomological and Natural History Society.
