Catalog of the fossil flies of the world (Insecta: Diptera) (Version 2.0)Catalog of the fossil flies of the world (Insecta: Diptera) (Version 2.0)
Originally published 29 July 1994 by Backhuys Publishers, Leiden, that printed catalog and its original website recorded over 3,100 species of fossil flies throughout the world. This current web version of that catalog (here completely redesigned and revised in 2014) presents the most up-to-date version of each family chapter of the catalog and will be continually updated as published information becomes available. In order to ensure that the information here is current, please send pdf files of your published articles dealing with fossil Diptera to: NealE [at]bishopmuseum[dot] org. Corrections and additions are welcome.
The list below indicates those families that are currently available for viewing online. The family order and classification used here (i.e., valid taxonomically, and/or what genus belongs in what family) follows the standards for the Systema Dipterorum combined with extinct family classification based in part on Pape et al. (2011) as well as recent papers and previous papers dealing with families not listed in that latter work. Listed below are all the family names of recent and fossil Diptera and links to current (updated) html files (with last revised date in last column -- those in red are the most recent updates) and pdf links to their original chapters in the 1994 catalog. Families that are extinct are indicated by an asterisk (*).
Acknowledgments
Many people have been thanked in the original 1994 catalog and many more have assisted since then to help update family chapters, help procure literature, and point out, ommissions, errors, and/or inconsistencies. There are too many to name individually, but their generous help was essential in getting Version 2.0 of this online catalog posted on the web.
Thanks to all!
A short note on phylogenetic classification
The actual phylogenetic classification of families within fossil and extant Diptera has been and will continue to be subject to change as more work is done to better circumscribe family definitions and determine relationships. To avoid frequent changes to this website when revised relationships are discovered -- and also to allow quick searching -- all families are listed here in alphabetical order, with cross reference to senior synonyms if they have been synonymized. The original 1994 catalog followed to a large degree the phylogenetic classification given in Carpenter's 1992 treatise on fossil Diptera genera. Much work has been done in the subsequent decades to improve upon that classification and, as a result, a large number of groups he treated as separate families have been relegated to synonymy under other families, while other taxa have been raised to familial status and new families proposed.
