Nomenclator Ciliophorum and Monograph of the Hypotricha, two works documenting the biodiversity of ciliates (Ciliophora)
Recent estimates about numbers
of ciliate species range from 3,000 (free-living only) over at
least 8,000 (including 200 fossil forms and 3,000 symbiotic species)
to about 40,000 (free-living only). The wide range demonstrates
that we are far away from knowing the true number of ciliate
species. Unfortunately, we do not even know the exact number
of species described so far and, more important, we do not have
serious estimates about the number of valid species due to lack
of detailed revisions in many groups of ciliates. To overcome
the first problem, the Nomenclator Ciliophorum is prepared. This
catalogue will contain all ciliate names ever published: (i)
basionyms of species; (ii) infrasubspecific taxa; (iii) combinations;
(iv) genera; and (v) suprageneric taxa. Furthermore, important
taxonomic papers are listed for each taxon, so that the nomenclator
will be useful not only for taxonomists, but also for ecologists
and molecular biologists who will benefit from such an index,
for example, in that they can find the updated name (combination)
of a certain organism easily. To estimate the valid number of
species it is necessary to revise a group in detail. The Monograph
of the Hypotricha (Springer) deals with a major group of ciliates,
the hypotrichs, which are a core-group of the spirotrichs. Hypotrichs
are widely distributed in limnetic and marine habitats, but also
in soil. About 1000 nominal species have been described and it
is estimated that 700 to 800 of them are valid. Four volumes
are available (Oxytrichidae; Urostyloidea; Amphisiellidae and
Trachelostylidae; Gonostomatidae and Kahliellidae) and volume
5 (Uroleptidae) will be published in 2013. The final volume is
in preparation and deals, inter alia, with the spiralled genera,
for example, Hypotrichidium, Strongylidium, Spiretella, Chaetospira.
A key to all taxa revised in volumes 16 will be a major part
of volume 6. When the monograph is complete, the hypotrichs will
be the sole very large group of ciliates which is revised in
detail. For further details, see www.protozoology.com/monograph.
The Monograph (vol. 6) and the Hypotricha part of the Nomenclator
are supported by the Austrian Science Fund (FWF), project P23415-B17.
