Abstract:Lange Zeit herrschte die Annahme SOBwasser-Rhizopoden w~ren, eigige seltene Formen ausgenomm.en, kosmopolitisch und die Frage nach der geographischen Verbrel. tung daher yon geringer Bedeutung.Da vlele der am beaten bekannten und nicht allzu seltenen Formen ubiquittir slnd und sich also in sehr verschledenen MiUeus (PH, CI-Gehalt, u.s.w., betreffend) Die damals schon bekannten F&lle, das Rhizopodenarten nur in beechr&nkten Gebiete bsobachtet werden (u.a.

Hoogenraad and Groot (1979) cited the species Nebela carinata (Archer) Leidy, N. marginata Penard, N. tubulosa Penard, and Hyalosphenia papilio Leidy as Northern endemics, although they had been found previously in Congo by GauthierLièvre (1954) and Decloitre (1965). Tentatively, the large Nebela speciosa Deflandre appears a good candidate for Northern endemism; its very large size ([200 lm, and even 278 lm) makes it a good flagship species and it has only been reported from North America, Germany and England (Deflandre 1936;Grospietsch 1958;Laminger 1973b;Ogden 1984).…”
