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 c onstitutes a well defined species, being more highly adapted to microa erobic, cold environments. Our observations on the Austrian population are compared with information available on specimens from the type lo cality in Spain. Morphological discrepancies, especially concerning ch aracteristics of Weber's organ and shape of the eggs are described and discussed. General ecological features indicate that the species is n ot restricted to meromictic or stratified lakes. To agree with the pro visions of the International Code of Zoological Nomenclature the origi nal spelling of A. miraclei Koste, 1991 is emended to A. miracleae Kos te, 1991.
