HRABYEIA-XERKOPHORA N-GEN N-SP, A NEW MICROSPORIDIAN WITH TAILED SPORES FROM THE OLIGOCHAETE NAIS-CHRISTINAE KASPARZAK, 1973

A new microsporidian, Hrabyeia xerkophora n.g., n.sp., is described from the coelomocytes of the body cavity of a freshwater oligochaete, Nais christinae Kasparzak, 1973 from Czechoslovakia. Infected coelomocytes are turned into xenomas 50 μm in size. Of the incompletely known life cycle, diplokaryotic sporonts developing in close contact with the host cell cytoplasm and diplokaryotic spores were studied. The spores of a Nosema-type have a gnarled caudal appendage encased with and compartmentalized by the exospore. © 1990, Gustav Fischer Verlag · Stuttgart · New York. All rights reserved.
