Abstract

This review deals with those Nematocera and Aschiza which were listed but not provided with Data Sheets by Falk (1991). There are 16 currently recognised families, comprising about 1,226 British Isles species, which are considered in this review.

The first account of threatened British Diptera was included in Shirt (1987). This listed 827 Diptera, 270 as Endangered, 226 as Vulnerable, 328 as Rare, and 3 as Appendix (extinct). Data sheets were included for 82 species (35 Endangered, and 47 Vulnerable), of which four were Nematocera in families treated in this volume, and three were Aschiza. This was followed by the publication of 'A review of the scarce and threatened flies of Great Britain (Part 1)' (Falk 1991). This presented species accounts of threatened species from the better-known families of British Diptera, together with a list of all British flies provisionally assigned to Red Data Book and Nationally Notable (now termed Lower Risk (Nationally Scarce)) categories.

The present volume deals with those Nematocera and Aschiza which were listed but not provided with Data Sheets by Falk (1991). Thus members of the following families are included: Mycetophilidae sensu lato (now five families: Bolitophilidae, Ditomyiidae, Diadocidiidae, Keroplatidae & Mycetophilidae sensu stricto), Trichoceridae, Mycetobiidae (sometimes included in Anisopodidae), Ptychopteridae, Dixidae, Culicidae, Thaumaleidae, Ceratopogonidae, Platypezidae, Phoridae, Lonchopteridae and Pipunculidae. The Atelestidae, included within the Platypezidae by Falk (1991) but now regarded as a family of Empidoidea are dealt with by Falk & Crossley (2005). The state of knowledge of the families dealt with here is variable.
