Abstract Five bryozoan species were encountered in a 15-day
survey of freshwater habitats in New Zealand. Listed in order of decreasing
frequency these were:
Fredericella sultana,
Plumatella repens,
P. emarginata,
Paludicella articulata,
and one plumatellid
species not previously described. Microstructural features of the floatoblast
annulus separate the
P. repens specimens into two distinct varieties,
named here
P. repens typica and
P. repens rugosa.
Paludicella, reported almost 100 years ago from the City of Dunedin
waterworks, was still found only in a single reservoir of that city. Species
distribution did not correlate significantly with water temperature, current
velocity, pH, or total dissolved solids. Two additional species believed to
occur in New Zealand,
Fredericella australiensis and
Plumatella
fungosa,
were not seen in this brief survey. An identification key
is provided for New Zealand bryozoans.
