About
this book 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 Kahliellidae) 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. Taxa included:
Afrokahliella,
Apogastrostyla, Apourosomoida, Bigonostomum, Ciliophora, Circinella,
Cladotricha, Cladotrichidae, Deviata, Echinodermata, Echinomeseres,
Engelmanniella, Fragmocirrus, Gonostomatidae, Gonostomum, Kahliella,
Kahliellidae, Meseres, Neogeneia, Neowallackia, Orthoamphisiella,
Paragonostomum, Parakahliella, Parakahliellidae, Perisincirra,
Protozoa, Pseudokahliella, Rigidohymena, Saudithrix, Stenotricha,
Trachelochaeta, Wallackia, Page 345, line 14: weakly (not
