Unter rund 90.000 gesammelten Tieren waren 37 Campodea (Campodea) plusiochaeta, Campodea (Campodea) Doppelschwänze. Sie teilen sich in 7 Arten auf, von denen die remyi, Campodea (Campodea) subdives, Campodea folgenden cavernicol sind: Campodea (Campodea) lankesteri, (Campodea) wallacei, Litocampa humilis humilis. Campodea (Campodea) wallacei, Litocampa humilis humilis. Abstract From 2007 to 2011, animals were collected from 82 caves All 7 species are new for Luxembourg: Campodea in the Grand Duchy of Luxembourg. Within 90,000 (Campodea) lankesteri, Campodea (Campodea) lubbocki, individuals, 37 were diplurans representing 7 species. Campodea (Campodea) plusiochaeta, Campodea (Campodea) The following species are classified as cavernicolous: remyi, Campodea (Campodea) subdives, Campodea Campodea (Campodea) lankesteri, Campodea (Campodea) (Campodea) wallacei, and Litocampa humilis humilis. wallacei, and Litocampa humilis humilis.
