Abstract

Cercomonads are important components of microbial food webs in soils and aquatic
sediments. Here, we investigated the general morphology, behaviour, life cycle and 18S rDNA
phylogeny of cercomonad cultures from a German grassland soil habitat. We describe ten new species
including two new genera from 23 strains. Three Cercomonas, two Eocercomonas and three
Paracercomonas species are described. Based on large phylogenetic distance and distinct morphology,
we erect two novel clade B genera near the root of the cercomonad tree. Nucleocercomonas nov. gen.
bears a number of characters unusual for cercomonads: Its anterior flagellum is extremely long, it
mostly does not glide, and in its most frequent life stage the cell body does not attach to the
substratum, but produces unattached pseudopodia. Furthermore, it has a unique nucleus with a
peripheral nucleolus that attaches to the nuclear envelope opposite the basal body connection.
Metabolomonas nov. gen. is extremely metabolic. It is characterized by a very high beating frequency of
the anterior flagellum, fast gliding, rapid changes in shape and strong cytoplasmic streams. A new
genus Brevimastigomonas is erected for the previously described species Paracercomonas anaerobica.
Closely related species of cercomonads may have a very different morphology.
