Collecting efforts on the rivers Sura and Moksha in the autono- mous Republic of Mordovia (Russia) have resulted in the detec- tion of 14 species of caddisflies, which are recorded from the Republic for the first time. To date, a total of 39 species are listed for the Republic, which is only a small fragment of the residential fauna. It is expected, that more than 200 species of caddisflies occur in the region.
