| Summary: | The bipolar distribution of fish leeches (Piscicolidae) has been considered and discussed by leech biologists for a long time. All cases of putative bipolar ranges of related taxa that occur in cold and temperate waters of both hemispheres and are absent in the tropics have been morphology-based hypotheses. Here, we present, for the first time, an instance of bipolar distribution substantiated by morphological and molecular data. The latter include the mitochondrial genes 12S rRNA, COI , ND1 and tRNA Leu, and the nuclear 28S rRNA. A new genus and species of Antarctic piscicolids, Austroplatybdellina prodiga , is described. The new leech was part of a Boreal-Arctic monophyletic group that is informally called ‘classic platybdellins’. That clade is the core of the non-monophyletic subfamily Platybdellinae. Austroplatybdellina prodiga gen. nov. sp. nov. was further classified as a member of a monophyletic group along with two Boreal genera, Crangonobdella and Beringobdella , which share a number of ... |
