Abstract
In the article the authors present an overview of the freshwater Oligochaeta and Polychaeta of the Croatian part of the Sava River from the Slovenian state border (i.e. Drenje) to the Serbian state border (i.e. Račinovci). The overview is based on available published data as well as on authors’ unpublished data collected since 1980. In the Croatian part of the Sava River, which is 562 km long (the total length is 940 km), 22 locations were analyzed. In total 43 species were found, out of which 39 belong to Oligochaeta and 4 belong to Polychaeta. The representatives of the Enchytraeidae family have not been determined down to the species level , and they are not included in the list. In this section of the Sava River the following six species have been found for the first time: Uncinais uncinata (Ǿrsted, 1842) – recorded at the 14th location; Propappus volki (Michaelsen, 1916) – recorded at the 19th and 21st locations; Aulodrilus pluriseta (Piguet, 1906) – recorded at the 16th location; Branchiura sowerbyi (Beddard, 1892) – recorded at the 12 th, 15 th, 21 st and 22nd locations; Psammoryctides moravicus (Hrabě, 1934) – recorded at the 4 th, 14 th, 15 th, 16 th, 19th and 20 th locations; Rhynchelmis limosella (Hoffmeister, 1843) – recorded at the 4 th location.
