ADDENDUM I received the two subsequent contributions of Niedbala while I was correcting the final proof of my paper. Niedbala, W. (1991): Revision of Oribatid mites from the Berlese collection I. Systematic position of Hoploderma hystricinum Berlese, 1908 and Hoploderma pavidum Berlese, 1913 (Acari: Oribatida). Genus, 2 (4): 327-335. Niedbala, W. (1993): Revision of oribatid mites from Berlese's collection. III. Redescription of species from Mesoplophoroidea and Euphthiracaroidea (Acari, Oribatida). Genus, 4 (1): 41-58. Obviously I could not incorporate the results expounded in Niedbala'

s two papers without going into great changes both in the concept of my paper and in the structure of the journal. The only alteration that I could do was to include Niedbala's new name: vanderhammeni for the restricted species of pavidus.
