Keywordsbiospeleology Gamasida Scandinavia trapping cave mites
Six caves from Scandinavia - two from South Sweden, two from the Baltic island of Gotland, and two from Norway near the Arctic Circle - were investigated for invertebrates by means of pitfall traps and by hand-picking. 1,765 Gamasina mites were found and determined to species and developmental stages. 37 species in 9 families were identified. One species alone, Parasitus loricatus, made up 75.0% of the total number of mites. Six other species, viz. Poecilochirus carabi, Vulgarogamasus oudemansi, Pergamasus robustus, Vulgarogamasus remberti, Cyrtolaelaps mucronatus and Vulgarogamasus kraepelini made up another 20.2% of the total number of mites. The numbers of individuals and species in this investigation exceeded by far those usually reported from investigations of caves in Europe, probably due to our use of pitfall traps.
