Material examined: NMB- 701a; 1 male; Switzerland, Basel-Landschaft, Binningen , private garden , 47°32′09.67″N, 7°34′38.27″E, 300 m; 01.06.2018; J. D. Gilgado et al. leg.; active capture . – NMB- 701b; 3 females; Switzerland, Basel-Landschaft, Binningen , private garden , 47°32′01.31″N, 7°34′52.79″E, 345 m; 10.08.2018; J. D. Gilgado et al. leg.; active capture . – NMB- 701c; 1 juvenile; same data but 28.09.2018 .

Distribution: Belgium, British Isles, Czech Republic, France, Germany, Italy, the Netherlands, Sweden. Also introduced into North America ( Kime & Enghoff, 2017).

Remarks: This species is usually found in decaying wood and organic matter (such as compost or debris) in contact with the soil. Cylindroiulus vulnerarius has probably an Italian origin, since most records outside this country are in urban or suburban environments ( Kime & Enghoff, 2017). However, as inferred from its presence in caves in Belgium and its abundance in the Netherlands and the British Isles, it is possible that in these areas this species had survived recent glaciations in microrefugia ( Kime, 2004; Kime & Dethier, 2010; Kime & Enghoff, 2017).
