Dinaric land leech Xerobdella anulata (Autrum, 1958)(Hirudinea: Xerobdellidae) in Serbia-the easternmost record in Europe

Abstract

Zagreb. Xerobdella anulata is a rare species of land leech endemic to the Dinaric Alps, distributed from southern Slovenia to northern Montenegro. Previously, the only known locality where this species had been recorded in Serbia was the village of Rastište on Mt. Tara, in the far west of the country. In this article, we present the second record of X. anulata in Serbia, found in the village of Sokolac, near Ljubovija. A single specimen was discovered on land near a stream in an area with a limestone substrate. We briefly describe the collected specimen, with particular emphasis on the arrangement of the gonopores. Despite the significant lack of distributional data for this species, we believe that western Serbia and the Podrinje region represent easternmost limit of species' complete distribution. Xerobdella anulata rijetka je vrsta kopnene pijavice koja je endem Dinarida i rasprostranjena je od južne Slovenije do sjeverne Crne Gore. Do sada je jedino poznato nalazište ove vrste u Srbiji bilo u selu Rastište na planini Tari, na krajnjem zapadu zemlje. U ovom članku predstavljamo drugi nalaz X. anulata u Srbiji, u selu Sokolac u blizini Ljubovije. Jedan primjerak pronađen je na tlu, u blizini potoka, na području s vapnenačkom podlogom. Ukratko opisujemo prikupljeni primjerak, s posebnim naglaskom na raspored gonopora. Unatoč značajnom nedostatku podataka o rasprostranjenosti ove vrste, smatramo da zapadna Srbija i područje Podrinja predstavljaju njezinu istočnu granicu rasprostranjenosti.
