Notes on coexistence of closely related Leiobunum rupestre and L. subalpinum (Opiliones, Eupnoi, Sclerosomatidae).

Two closely related, syntopic species, Leiobunum rupestre and L. subalpinum, spend the day at apparently randomly distributed resting sites. In this preliminary research, we studied differences in their microclimatic preferences at a locality in the Pohorje Mts.
