The Urostyloidea are a wide workforce of hypotrichs comprising limnetic, marine, and terrestrial species in famous genera comparable to Holosticha, Urostyla, and Pseudokeronopsis. Holosticha pullaster is without doubt one of the commonest hypotrichs in clean and salt water.
This monograph is the second one of a sequence treating the hypotrichs, an immense a part of the spirotrichous ciliates. just like the first quantity, overlaying the Oxytrichidae, it summarises 230 years of morphological, morphogenetic, faunistic, and ecological info, heretofore scattered in a few 1,300 references from worldwide.
Dichotomous keys result in 36 genera and subgenera comprising 153 species are illustrated by means of greater than 2100 figures. The treatise deals taxonomists, cellphone biologists, and ecologists an intensive and up to date revision, delivering a close record of synonyms, a dialogue of the nomenclature and systematics, and an intensive description of the morphology and ecology, together with just about all released faunistic files, for every species.
Together, the monographs at the Urostyloidea and the Oxytrichidae establish greater than 320 species of hypotrichs, that are a massive
