Drei für Deutschland neue Zwergspinnen aus dem bayerischen Alpenraum (Araneae: Linyphiidae, Erigoninae)

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.
