The naidid genus Branchiodrilus is very common in Asia, and according to some authors, the first discovery of this aquatic oligochaeta in Europe was in the Botanical Garden in London together with tubificid species Branchiura sowerbyi. This specimen described in 1890 as Branchiodrilus semperi. Since then, it has been recorded in the Netherlands, Belgium, France and Slovakia as a species B. hortensis. A recent molecular phylogeny suggested that species complexes may occur within the genus Branchiodrilus, potentially represent 10 different species. However, morphological examination has grouped all specimens from the Palearctic Region and suggests that all of them belong to the same species, probably B. hortensis, one of three nominal species of the genus. Furthermore, the latest molecular analysis conformed that the Oriental region might be the centre of origin, from which Branchiodrilus species have dispersed and radiated. In our latest investigation of the Danube River (September 2018 and April 2019), along a river section of 588 rkm in Serbia, we recorded Branchiodrilus specimens at four localities: Ram (8 ind.), Veliko Gradište (14 ind.), Donji Milanovac (2 ind.), Kladovo (56 ind.). The scattered findings and native distribution of this worm suggests that the introduction in the Danube River has probably been human mediated. These new records are valuable contribution to the knowledge of the species distribution. In this phase we are not able to predict the possible effects of Branchiodrilus on aquatic ecosystems, and therefore, further monitoring of its distribution and population dynamics is necessary.
