This checklist has been prepared by Frans Janssens, since 1976, member of the Royal Entomological Society of Antwerp, Belgium; since 1998, laboratory associate of the Department of Biology, Evolutionary Ecology Group, University of Antwerp, Belgium.
The main purpose of this checklist is to resolve synonymy related problems. Typical example: given a taxon name, verify whether or not it is currently valid and if it is not valid what is then its currently valid name.

This taxonomic checklist includes all Collembola species of the world. Included are all valid names with a complete list of synonyms in their original combinations with authors and dates. Old as well as new collembolan literature has been and is causing confusion due to inaccuracies and errors. Many of these have been corrected or will be corrected by examining the original descriptions for taxa and correctly applying the rules of zoological nomenclature. Tentative taxonomic decisions, such as synonymizing taxa or using new classification schemes, are applied to settle open issues and/or resolve conflicting opinions. The checklist is a reflection of the current literature. The classification scheme is based on a compilation of recent classifications. This checklist is kept up to date with newly published papers and corrections are applied when errors are reported. Last but not least, the checklist is a working document, a discussion platform to share opinions on nomenclature, taxonomy, systematics and phylogenetics.

I would like to hear from anyone who has corrections or additions to the list.

I would like to thank

My friend Gie Wyckmans sent me this little poem after he lost his way in the website on 2001.03.22:


dwalen door de paginas van Frans Janssens....
kwelen hoog de vogelaars
en vind geen discrepancies
die lapt furcula aan de laars
en nonsens
en janssens
hoe zit de steel weer aan de vork
hork hork
