PREFACE TO THIS 2010 UPDATE
This update to A Catalog of the Cecidomyiidae (Diptera) of the World (Gagné 2004b) will allow scientists
and others to track nomenclatural changes and the additional 680 species and 185 genera that have been described since
the cut-off date (sometime in 2003) for Gagné (2004b). The present totals are 6131 species and 783 genera, . This
update lists the taxonomic papers on the group known to me as of March 21, 2010. The original introduction that
follows is changed in minor ways to remain current, but the main points and modus operandi remain the same.
Some changes in presentation of the catalog are made here. All genera, species, and literature cited new to this
update are flagged by an asterisk. All fossil species, including those cited in the original catalog, are now preceded by a
dagger to designate them more clearly. Some commentary following particular genera has been made, added to, or
changed because of new developments or personal realizations. New family group names that have been proposed
since Gagné (2004b) are discussed under Appendix 1, Classification of the Cecidomyiidae. The commentary in that
section is largely rewritten to reflect changes that have occurred in the family since Gagné (2004b). The original
Appendix 2 of Gagné (2004b) listing new type species, species, names, synonyms, and combinations has been omitted.
No new formal taxonomic changes are made here. Some 20 species are now seen to be misplaced in their
present genera or nomina dubia. They remain as were in Gagné (2004b), but are clearly marked, mostly as “per M.
Jaschhof (in litt.).” Future authors are welcome to formalize these suggested changes.
Since 2003, I have found or been made aware of some errors and a few missed papers in the original catalog.
These are remedied in this present update and are listed for the record in an Errata section that follows "Literature
Cited."
Mathias Jaschhof of the Senckenberg Deutsches Entomologishes Institut, Müncheberg, Germany has carefully
reviewed the sections on Catotrichinae, Lestremiinae, and Micromyinae, and has helpfully agreed to keep track of
changes to these groups, the wood midges, from now on. Netta Dorchin and Keith M. Harris kindly read and
commented on Appendix 1 for this update, as did Junichi Yukawa, who also helped with a complete list of literature,
changes and additions by him and colleagues so that I could double-check those sources and results. I am grateful also
for the general reviews of the manuscript and suggestions made by Alexander S. Konstantinov and Allen L. Norrbom,
both of the Systematic Entomology Laboratory (SEL). I thank Mark Metz of the SEL for his technical advice and
expertise, and Alma Solis, Research Leader of SEL, for making this update available on the Laboratory's website.
