Dr. Baert (Royal Institute of Natural Sciences) kindly put the relevant collections at
my disposal. Although Opiliones were never the object of a sampling session,
the bottles were rich enough to keep me happy for several years on row.
I added some material from my own entomological studies and from the former
Laboratory of Oecology (State University Ghent).
When finally the number of Opiliones minded
people doubled with W. Slosse, I knew that distribution maps with not too many blancs where within reach. His umbrella sampling-method is very succesful,
as proved by the explosion of recent observations in the western part of the country.
