REMARKS

This species was originally described from mosses along a pond margin in Germany. Subsequently, D. disjunctus was also found in the hyporheic zone of streams and rivers, as a stygophylous element, and in surface freshwater, as benthic element. Its distribution is relatively wide and scattered across Europe and the species is considered rare in terms of its frequency of occurrence. It has also been recorded from Japan, but this record was questioned by Stoch & Pospisil (2000). It is already known from Germany, France, Sweden, Austria, Czech Republic, Poland and Ukraine. Here recorded for the first time in the Mercantour National Park.
