This article is a translation and a revision of
Janssens, F. 1997. Collembola uit de omgeving van Friuli-Venezia Giulia, Italië. Antwerpse Vereniging voor Entomologie, Entomo-Info, Jaargang 8, 1997, nr 2, p.54-56.

Currently being revised.


In February 1996, Dr Gianluca Governatori of the Universit… degli Studi di Udine mailed me six samples for determination with Collembola specimens from the (pre-)Alps from the environments of Friuli-Venezia Guilia, Italy.

End January, 1997, I finally determined the last specimen... The following is a summary of what I have found in the samples. Some specimens are detailed with a short description.
