Leptoiulus bertkaui (Verhoeff, 1896) Iulus bertkaui Verhoeff, 1896 . Distribution CH , DE, FR-FRA, LU. Meuse, Rhine and Weser river basins. Habitat Humid areas, usually in close proximity to rivers; these may be open (meadows and marshes) or more frequently closed (wooded river margins, inundation forest). It prefers natural or semi-natural biotopes. In the Meuse Basin associated with woodland ( Salix , Alnus , Betula , Quercus , Fagus ) on greensand or in valleys in Jurassic limestone. Most active in springtime. Found as high as 1000 m above sea level in the south of its range. Remarks For almost a century it was known only from the Rhine Basin. Then it was reported from the Rhône Basin, but only near Geneva in Switzerland , not very far from the headwaters of the Rhine (Pedroli- Christen 1993). More recent finds in Alnus and Quercus woods in the Meuse Basin in France and the upper Weser Basin near Kassel in Germany ( Voigtländer & Hauser 1998 ) add extensively to its range.
