The arachnofaunistic exploration of the German Alps is still in process. Recent investigations in subalpine and alpine habitats of Bavaria yielded 13 species new to Germany. For 5 taxa the collecting sites are reported, together with comments on general distribution and ecology. Cryphoeca Iichenum nigerrima is a locally-endemic relict, which probably has survived glaciation on the nunatak system. Its distribution area is restricted to few mountain-ranges in the Northem Calcareous Alps, comprising less than 2500 qkm. Two species,Erigone cristatopalpus and Talavera monticola, are endemic to the Alps and adjoining mountains. Micaria aenea shows a boreomontane disjunction. Heliophanus Iineiventris is widely distributed in the southern Palearctic.
During the survey of epigeous spider communities in the Bavarian Alps (Germany, Upper Bavaria), three species of Erigoninae were recorded from Germany for the first time. Micrargus alpinus and Silometopus rosemariae are endemic species of the Alps, Panamomops palmgreni is endemic to the Alpine mountain system. For each species present knowledge on distribution, habitat and phenology is summarized. As Micrargus alpinus was described in 1997, faunistic and ecological data are still very poor. Niche differentiation between the closely related species of the Micrargus herbigradus-group is discussed.
