Abstract : A checklist of the Rotifera Fauna from the Rhodope Mountains with data about the occurrence of the species is presented. Up to date, 53 taxa from different taxonomical levels were recorded from the freshwater bodies in the Rhodope Mountains. Most of these inhabit the pelagic and littoral zones of different types of natural and artifjcial (reservoirs and fjsh farms) water bodies. Only a few of them were found in other types of habitats. Development and the current state of rotifer faunistics in the Rhodope are discussed and suggestions are given, where new rotifer taxa may be found. Keywords : Rotifera, Bulgaria, Rhodope Mountains, distribution, faunistics, checklist Introduction Tie aim of this study is to summarize the existing data about the Rotifera fauna in the Rhodope Mountains. Also, some new data about the species and their habitats unpublished before are given. In total, 53 taxa of Rotifera at difgerent taxonomic level – genus, species and subspecies, from difgerent types of water bodies –natural, artifjcial and interstitial zones have been found (Tab. 1). In the check list, several subspecies of rotifers that have repeatedly been recorded in numerous recent papers concerning the Rotifera fauna in the Rhodope are included. Tie classifjcation system of the listed Rotifera follows the papers of Voigt (1957), Rudescu (1960), Kutikova (1970, 1994), Koste (1978), Segers (2002), Wallace et al. (2006). Tie used subspecies names mostly from the Brachionidae family are according to the species 2000 it is Catalogue of Life (Segers, ed. 2007). Tie classifjcation of genus Lecane in the checklist follows Segers (1993, 1995, 2006) and Segers & Rico-Martinez (2000). Tiese authors reject the validity of the subgenera in the genus Lecane . L. (s. str.), L. ( Hemimonostyla ) and L. ( Monostyla ), used previously by Kutikova (1970), Koste (1978) and Koste & Shiel (1990).

More than 60 % of the recorded species and subspecies of Rotifera in the Rhodope were established for the fjrst time by Naidenov during the period 1960- 1984 (Naidenov 1964 a, b, c, 1972, 1976, 1977 a, b, c, 1978, 1984, Naidenov & Sais 1983). Tie papers of Ludskanova (1967, 1970, 1972) also contributed signifjcantly to the kowledge base of the Rotifers in the Rhodopes. Check list of Rotifera found in the water bodies of the Rhodope Tie list contains the rotifers found in the water bodies in the Rhodope with localities and authors who have found them. Tiey belong to 1 class, 1 subclas, 2 superorders, 2 orders, and 10 families (Tab. 1).
