New records of terrestrial tardigrades (Tardigrada) from Ceahlau National Park with zoogeographical and taxonomical remarks on Romanian water bears

Fourteen tardigrade species have been found in moss and lichen samples collected at 14 sampling sites in the Ceahlau National Park in Romania. The study was carried out during the summers of 2009 and 2011, and 613 tardigrade specimens and 11 eggs were found in total. Among them, both Milnesium asiaticum Tumanov, 2006 and Milnesium granulatum (Ramazzotii, 1962) are new records for Romania. M. granulatum was originally described from Chile, later reported from Italy, and this is the second report of this species from Europe. In this paper, we also provide a comprehensive list of the tardigrades known from Romania altogether with zoogeographical and taxonomical remarks on all known Romanian water bears.
