Abstract
In the framework of a long-term project launched by the Stelvio National Park for monitoring the spatio-temporal patterns in plant, arthropod and vertebrate species assemblages, the results on the sampled cholevid species are reported. The abundance of specimens and the distribution of species has been studied in relation to nine environmental variables. Five species of the tribe Cholevini were sampled during this research: Apocatops nigrita, Catops coracinus, Catops fuliginosu, Catops nigricans and Catops tristis. The most abundant and frequent species were Apocatops nigrita and Catops coracinus. The effect of the environmental variables on the distribution of two of the most abundant species (C. coracinus, A. nigrita) was tested and described. Updated information about the distribution and ecology of the five sampled species were provided.
