Criodrilus ochridensis Georgevitch, 1950

Criodrilus ochridensis: Georgevitch, 1950: 77 .

Habitat. Aquatic (Georgevitch 1950).

Distribution on the Balkans and Anatolia. Macedonia (Lake Ochrid, St. Naum: Georgevitch 1950); Turkey (No records).

Remarks. Until now, this species is known only from the type locality from Macedonia. However, according to Fauna Europaea, C. ochridensis is present in Macedonia and Albania, but this species has never been registered in Albania. Despite of extensive investigations in the area of Lake Ochrid in last fifty years this species has not been registered again (Smiljkov et al. 2005). According to Kerovec and Mršić (1981), C. ochridensis is a synonym of C. lacuum, but no explanations were given, hence this opinion is not acceptable. Generally, it is clear that the presence of species C. ochridensis in Macedonia needs confirmation.
