| Abstract: | The genus Cryphoeca is represented in the Alps by more species than previously assumed. Affinities and distribution patterns are of interest for zoogeography. They seem to be influenced by the Pleistocene glaciations. C. lichenum L. Koch and C. nivalis Schenkel, still listed by Bonnet (1956) as junior synonyms of the type species C. silvicola (C. L. Koch), should be ranked as full species; furthermore there are at least 2 high-alpine forms occurring only in very restricted areas, C. l. nigerrima subsp. nov. and Cryphoeca sp. The 5 taxa can be divided into 2 spp.-groups, each containing a forest-species and 1-2 high-alpine forms. They are characterized and discussed, and a key is included. Patterns are interpreted as follows: the forest-species C. silvicola and C. l. lichenum represent parental forms, overwintering in arboreal refuges outside the Alps and extending and reducing their areas with changing ecological conditions. Allied taxa occurring in and restricted to high biota have evolved from populations isolated in glacial times: C. nivalis (Switzerland), C. l. nigerrima subsp. nov. (northern Tirol [Austria]), Cryphoeca sp. (Southern Alps). |
