New and additional records of earthworms (Oligochaeta: Lumbricidae) from Bulgaria: first finding place of endemic species Cernosvitovia munteniana on the Balkan Peninsula

Identifying the earthworm material recently collected from different parts of Bulgaria (Rila Mountain, Danube plain, Thracian Lowland and Sub-Balkan valleys) resulted in twelve records of lumbricids, including two earthworm species discovered for the first time in the country. The occurrence of Cernosvitovia munteniana Zicsi & Pop, 1991 in Bulgaria and also on the territory of the Balkan Peninsula is firstly recorded. The peregrine compost-worm, Eisenia andrei Bouché, 1972, proved to be another new finding for the country. By including these new records, the number of earthworm species known from Bulgaria is raised to 48.
