At three sites in Tyrol (Austria), in Central Alps around Obergurgl ca. 2000 m, and in N. Calcareous Alps around Innsbruck, at ca. 1100-1200 m a.s.l., 25 spider species have been trapped from deep scree, belonging to Mimetidae (I sp.), Theridiidae (2), Linyphiidae (12), Lycosidae (1), Agelenidae (2), Hahniidae (1), Dictynidae (1), Amaurobiidae (1), Liocranidae (2), Gnaphosidae (1), Thomisidae (1). There are some stenotopic inhabitants of the scree system, esp. Rugathodes belIicosus (Theridiidae), Micrargus apertus, Lepthyphantes notabilis, Porrhomma myops (Linyphiidae), present also in Czech Republic, and some regular invaders from the surface layers. Another two stenotopic inhabitants of the scree system of Central Europe were not encountered at the sites investigated, i.e. Bathyphantes simillimus buchari and Wubanoides uralensis (Linyphiidae).
