DIPTERA OF THE READING AREA

Editor: Miss E. M. Nelmes • For the purpose of this paper the Reading area is defined by a circle of 20 km. radius centred on Reading Museum, including parts of the Watson­ ian vice-counties 12 (North Hampshire), 22 (), 23 (Oxfordshire), and 24 (Buckinghamshire). Within this area, the 1974 boundary changes have transferred part of the former county borough of Reading north of the Thames to Berkshire. Thus the localities of Caversham and Emmer Green are contained in VC 23 but are in the new county of Berkshire. In VC 22, Kingstanding, Moulsford Downs and Unhill now belong to Oxfordshire. Within the Reading area the late Dr. Eric Burtt took most of his coll­ ection of British Diptera, now in Reading Museum. The list which follows is based on his work and may stand as a tribute to his skill and diligence. Jonathan Cole, collecting in a more restricted area over a shorter period, has contributed a list of species actually more numerous than Dr. Burtt's. I am also indebted to P . J. Chandler, Adrian Pont and Alan Stubbs for records of flies which they have captured in the area, to Roger Leeke who submitted 100 specimens for determination, including the rare Minettia dissimilis Col . , and to Adrian Pont, P. J. Chandler and E. A. Fcnseca for assistance with the determination of Mycetophilidae, Platypezidae, Dolichopodidae, Sepsidae and Anthomyiidae. P . N. Crow has also supplied some rarit i.es. For completeness and ease of reference I have incorporated here the information contained in articles by Cole (Reading Naturalist 1959 and 1966) and Leatherdale (ibid. 1961 and 1964) and the annual reports in the same journal of Reading and District Natural History Society's Recorder for Ento­ mology. To the best of my knowledge there ts no ot.her publtshed work on t.he Diptera of this area. Where months of occurence are quoted in the form "May to September", I imply that the fly has also been taken in each of the intervening months; otherwise I have used the form "May, September" . to indicate that there are no records from June, July or August . This does not apply to the years (there is seldom a continuous record of annual captures) but I haye occa­ sionally used the form "1950, 1970" to emphasise that there have been two isolated captures in those years only, separated by a long interval without records . Otherwise only first and last dates are given, with no implication as to the intervening period . Following a convention adopted in the arrangement of the Reading Museum collection by Dr. Burtt, localities for each species are arranged in geog­ raphical order from NW to SE. The nomenclature and species order is that of Kloet and Hincks, " Check­ list of British Diptera" (2nd. edition, Royal Ent. Soc. 1976) in which species are arranged alphabetically within each genus and subgenus. A few changes published since the appearance of Kloet and Hincks are given in the footnotes. The observant will notice that here and there I have altered a termination in order to restore the concord between a noun and its adjective following a change of generic name. 2
