Additional notes on taxonomy and ecology of Anuraeopsis miracleae Koste, 1991 (Rotatoria:Monogononta) from an Austrian alpine lake

Although closely resembling Anuraeopsis fissa, Anuraeopsis miracleae constitutes a well defined species, being more highly adapted to microaerobic, cold environments. Our observations on the Austrian population are compared with information available on specimens from the type locality in Spain. Morphological discrepancies, especially concerning characteristics of Weber's organ and shape of the eggs are described and discussed. General ecological features indicate that the species is not restricted to meromictic or stratified lakes. To agree with the provisions of the International Code of Zoological Nomenclature the original spelling of A. miraclei Koste, 1991 is emended to A. miracleae Koste, 1991.
