我们在莱茵河中发现了一种具有显著特征的自由生活的缘毛纤毛虫。用标准方法研究其形态和18 S rRNA基因序列。[医]阿氏山慈姑sp.有几个特点。(i)有普通的游动体、大型游动体和小型游动体，它们在盘状基部（柄盘）上形成半球形的莲座，锁定宽约18 μm、长可达2 mm的连续收缩的菌落柄。(ii)柄肌丝仅与小虫相连。(iii)一个莲座丛包含多达50个的游动体，它们彼此不相连，但单独地附着在带有鞘的茎盘上。(iv)普通的游动体呈柱上型，喇叭形（长：宽约6：1），大小约180 × 30 μm，在口腔和背侧之间的顶部下有一个椭圆形大核。(v)游动体的肌丝系统可以单独收缩，在细胞狭窄的后半部形成管状结构。(vi)银线纹属于横纹型。(vii)口器结构正常，第3小笔的第1运动体近端明显缩短。（viii）18S rRNA将A.阿恩蒂; sp.作为一个独特的谱系，靠近涡孢属和Carchesium。这些数据是用来提供一个改进的属Apocarchesium的诊断。特征（i）-（iii）和分子数据表明，Apocarchesium可能是一个新的peritrich科的模式属。
We discovered a free-living peritrich ciliate with outstanding features in the River Rhine. Its morphology and 18S rRNA gene sequence were studied with standard methods. Apocarchesium arndti n. sp. has several peculiarities. (i) There are ordinary zooids, macrozooids, and microzooids, which form a hemispherical rosette on a discoidal base, the stalk dish, locking the ~ 18 μm wide and up to 2 mm long, spirally contracting colony stalk. (ii) The stalk myoneme is connected only to the microzooids. (iii) A rosette contains up to 50 zooids not connected to each other but individually attached to the stalk dish with the scopula. (iv) The ordinary zooids are epistylidid, trumpet-shaped (~ 6:1 length:width), about 180 × 30 μm in size, and have an ellipsoidal macronucleus subapically between oral cavity and dorsal side. (v) The myoneme system of the zooids, which can contract individually, forms a tube-like structure in the narrow posterior half of the cell. (vi) The silverline pattern belongs to the transverse-striate type. (vii) The oral apparatus is of usual structure, with kinety 1 of peniculus 3 distinctly shortened proximally. (viii) The 18S rRNA places A. arndti n. sp. as a distinct lineage near Vorticella and Carchesium. These data are used to provide an improved diagnosis of the genus Apocarchesium. Features (i)–(iii) and the molecular data indicate that Apocarchesium could be the type genus of a new peritrich family.
