| Abstract |
The re-identification of archive samples revealed that the first records of Corophiidae in Hungary (1917) were erroneously attributed to Chelicorophium curvispinum; the first species expanding its range in the River Danube was in fact C. sowinskyi, while the actual colonization of the Danube and its tributaries by C. curvispinum took place somewhat later. In a sample of 1943 in the River Tisza C. maeoticum was found, representing its first and so far only record for Hungary. At present C. curvispinum is the most widespread corophiid in the country, while the once probably continuous range of C. sowinskyi in the Carpathian Basin has become fragmented; three isolated populations exist in the rivers Danube, Drava, and Tisza. In 2007 C. robustum was found for the first time in Hungary, spreading downstream in the Danube. Our records denote that it has the potential to become an important member of the benthic macroinvertebrate assemblage, and may have negative effects on the corophiid species already present. |
