During the last three decades the authors have carried out soli Zoological re-search by sampling with Berlese extractors in variotis paris of the worid. main lyin tropical and subtropical regions. These studies h ad a dual aim. On the oneliand. by making thorough examinations we hoped to hecome acquainted with theoribat id latina of these region s. on the other hand. by acquiring a ricli and highlydiverse materiai, we hoped to document and preserve the soli fauna for posteri tyin vlew of the generat ei viron mental degradation whicli is heco ming more and
These Berlese samples were so ricli in material that we and our collabora-cors have described numerous mite species in severat hundred articies. The Mu-seum d 'Histo ire Naturelle of Geneva has also supported many of these researches, the material of whicli has been mostly elaborated by the junior aut hor. Extensive explorations ait over the world have yiel ded a litige quantity of collected materiai, of whicli only a fraction has yet been made public. It is uia likely that this work will be completed in the near future, especialty that concerning the ori balid mites. Consequently we have decided not to proceed with the regular step-bystep publication, but instead give priori ty to those taxa which seem to solve sonae taxonomic problenas by bridging larger gaps, thereby hel ping those colleagues whose primary aim is to create an e Volutionary System.
