50 spider species (Theridiidae 2, Erigoninae 16, Linyphiinae 10, Agelenidae 2, Lycosidae 7, Gnaphosidae 7, Philodromidae 3, Thomisidae 1, Salticidae 2) are recorded from 13 mountains in N-Tyrol and S-Tyrol, 2471-3281 m. According to ecology and areography they group into assemblages already known: euryzonal species with a wide distribution in altitude (S = 8), species occurring mainly in nival environments (S = 7), casual invaders (S = 5), arctic-alpine species (S = 11), species endemic to the Alps (S = 16) as to the Alpine system (S = 7), holarctic mountain species present also in Central Asia and in N.-America (S = 3). Further records are given for Opiliones (S = 3), Pseudoscorpiones (S = 3), Dipiopoda (S = 5), Heteroptera (S = 1), Coleoptera (S = 18), including "high" records from 2900-3100 m for some species of the grasslands of the alpine zone: Mitopus morio (Opil.), Carabidae (5 species), Chrysomela collaris (Col.), Selatosomus rugosus (Col.). Distribution maps are added for two species endemic in the N. Calcareous Alps (Karwendel) (Lepthyphantes severus, Cryphoeca lichenum nigerrima (Ar.)) and for further high alpine species with an area limit along the western (Cryphoeca nivalis, Drassodes heeri (Ar.)) and the eastern border of the Otztal and Stubai Alps respectively (Diplocephalus rostratus (Ar.), Trimerophorella rhaeticum (Dipl.)). Apparently these maps indicate a more continuous distribution from the Southern and South-Western parts of the Alps to Tyrol for some high alpine species, which was already shown for Acantholycosa pedestris (Ar.). Eventually such a distribution might be valid also for some species which are now known only from a few scattered localities (Metopobactrus nodicomis (Ar.), Neobisium dolomiticum (Ps.)).
