From the introduction:
"The volume Tullbergiidae presented here is an entirely revised version, updated and translated into English, of the ﬁrst edition (which appeared as Volume 1 of the Synopses on Palaearctic Collembola: Tullbergiinae [1994; in German] by Bettina Zimdars and
Accepting the proposition of Deharveng (2004), the subfamily Tullbergiinae is again elevated to the rank as Tullbergiidae Bagnall, 1947. The diagnoses of species and genera have been completed by our own studies, mainly based on the collections of the Senckenberg Museum of Natural History Gorlitz as well as on material kindly lent to us especially by the Museum of Natural History Geneva, Switzerland, the Museum of Natural History Paris, France and by several colleagues (see acknowledgements). We further took into account studies concerning the sexual status of (partly or possibly totally) parthenogenetical species of the Tullbergiidae (Zimdars & Dunger 2000).
The diagnoses of the 18 palaearctic genera (from 31 genera worldwide) and 64 hol- or palaearctic species are based on original material as far as possible. Nevertheless, to a large extent this monography represents a revision of literature data. Occurrence records have been checked concerning their actuality after new descriptions.
Geographically, arctic species are included from Greenland up to north-eastern Asia as well as species from the Chinese and Himalaya regions north of 30 degrees of latitude. Data available up to the end of 2010 were taken into consideration."
