Summary The fauna of endobiotic ciliates from the gut of domestic horses in South Africa was investigated. Samples were collected from horses that were kept in stables, as well as free-grazing ones. Ciliates from 39 species belonging to 22 genera were found, most of them were common in the intestinal fauna of horses. In addition, Spirodinium nanum , suggested to be specific for zebras, and Blepharosphaera ceratotherii , previously found in rhinoceros and zebras, were found. Immunofluorescent staining was used to study the organization of the microtubule cytoskeleton in some endobiotic ciliates. The structure of the ciliature of Ditoxum funinucleum is described for the first time. Conclusions are made about peculiarities of the organization of microtubule cytoskeleton in spirodiniids in the context of the taxonomy of this group of trichostomatids.

Summary The order Leptomyxida (Amoebozoa, Tubulinea) unifies species capable of altering their morphology from monopodial, clavate in active locomotion to flattened ramose or branched while feeding or resting. Species belonging to this order are very polymorphic and are hard to distinguish at the morphological level. The molecular data, namely – gene sequences, remain the primary differentiating character, especially within the genus Leptomyxa . We have isolated a new representative of this genus, Leptomyxa regia n. sp., from the top layer of sediment collected from an artificial pond in Izmailovo Park in Moscow (Russia). A remarkable characteristic of this species is that being monopodial, it moves without forming a pronounced hyaline cap. The latter is visible only at the beginning of locomotion or in non-directed movement. In addition, it differs from other species in the 18S rRNA gene sequence. We provide morphological and molecular data on this remarkable species of Leptomyxida.
Leptomyxida目(变形虫目，管状目)统一了能够改变其形态的物种，从主动运动时的单足棒状到进食或休息时的扁平分枝或分支。属于这一目的物种是非常多态的，在形态水平上很难区分。分子数据，即-基因序列，仍然是主要的区分特征，特别是在Leptomyxa属中。我们从莫斯科(俄罗斯)伊兹梅洛沃公园人工池塘收集的沉积物顶层分离出该属的一个新代表，Leptomyxa regia n. sp.。这种鱼有一个显著的特点，那就是它是单足的，移动时不形成明显的透明帽。后者只有在开始运动或无方向运动时才可见。此外，它与其他物种在18S rRNA基因序列上有所不同。我们提供了这一显著物种的形态和分子数据。

The species of the genus Ophryodendron are epibionts of various invertebrate animals. They are rarely found in nature, and very little research has been dedicated to them recently. Ophryodendron abietinum , an epibiont of a hydrozoan Obelia longissima , was discovered in the White Sea for the first time. This study provides a description of O. abietinum life cycle forms and host-epibiont interactions.
