A myxosporean species found to develop in the liver of 10 out of 24 common shrews, Sorex araneus L., caught in South Bohemia, Czech Republic, was identified as Soricimyxum fegati Prunescu, Prunescu, Pucek et Lom, 2007, the unique representative of the genus and the first myxosporean species known to develop from plasmodia to spores in a terrestrial mammal. The original description of this species, based on fixed material, is supplemented with new data based on fresh material and with partial sequence of SSU rDNA (GenBank Acc. No. EU232760). Phylogenetic analysis of SSU rDNA revealed that S. fegati is closely related to myxosporeans infecting gall bladders of freshwater fish.
