The present monograph is the fourth of six volumes which review the
Hypotricha, a major group of the spirotrichs. The book is about the
Gonostomatidae, the Kahliellidae, and some taxa of unknown position
in the hypotrichs. Gonostomum was previously misclassified in the
Oxytrichidae because its type species Gonostomum affine has
basically an 18-cirri pattern, which is dominant in the
oxytrichids. A new hypothesis, considering also molecular data,
postulates that this 18-cirri pattern evolved in the last common
ancestor of the hypotrichs and therefore it appears throughout the
Hypotricha tree. The simple dorsal kinety pattern, composed of only
three bipolar dorsal kineties, and gene sequence analyses strongly
suggest that Gonostomum branches off rather early in the
phylogenetic tree. Thus, the Gonostomatidae, previously synonymised
with the oxytrichids, are reactivated to include the name-bearing
type genus and other genera (e.g., Paragonostomum, Wallackia,
Cladotricha) which have the characteristic gonostomatid oral
apparatus. The Kahliellidae are a rather vague group mainly defined
via the preservation of parts of the parental infraciliature. The
kahliellids preliminary comprise, besides the name-bearing type
genus Kahliella, genera such as Parakahliella and its African
pendant Afrokahliella or the monotypic Engelmanniella. In total 68
species distributed in 21 genera and subgenera are revised. As in
the previous volumes almost all morphological, morphogenetic,
molecular, faunistic, and ecological data, scattered in almost 700
papers, are compiled so that the four volumes (Oxytrichidae,
Urostyloidea, Amphisiellidae and Trachelostylidae, Gonostomatidae
and Kahliellida) provide a detailed insight into the biology of
almost 500 species of hypotrichs. The series is an up-to-date
overview about this highly interesting taxon of spirotrichous
ciliates mainly addressed to taxonomists, cell biologists,
ecologists, molecular biologists, and practitioners.
