Abstract

The enchytraeid fauna of the Rax mountain range (Austria) was investigated. Samples were taken from five different habitats: under Pinus mugo, under Picea abies, under Larix decidua, from a mixed forest (P. abies with Betula pendula) and from an alpine meadow. Forty one enchytraeid species belonging to 12 genera were found and additionally the terrestrial polychaete Hrabeiella periglandulata. In addition to the very frequent species, Fridericia discifera Healy, 1975, another species with very similar spermathecae but differing in some traits was also observed. The characters which could be used to discriminate this new species, F. alpica sp. n. from F. discifera are discussed in this paper. Another species collected from the study site, F. raxiensis sp. n. was also new to science and is described based on both morphological and molecular taxonomic methods.
