The morphology, ontogenesis, encystment, and 18S rRNA gene sequence of a new soil hypotrich ciliate, Kahliella matisi, were studied. Main characteristics of K. matisi are: (1) two short and six longitudinal cirral rows right of the adoral zone of membranelles and four longitudinal rows left of it; (2) three dorsal kineties, of which kinety 1 extends along the left cell margin, kinety 2 runs in a slightly sigmoidal line, and kinety 3 is distinctly shortened posteriorly. Ontogenesis is similar to that in congeners, especially in the development of the marginal rows and long dorsal kineties, the preservation of some old cirral rows after division, and the direction of the neokinetal wave. However, there are some peculiarities: (1) reorganization of the proximal parental adoral membranelles; (2) splitting of opisthe's anlage II into the cirral streak II and III; and (3) formation of the parental cirral row R3 from anlagen IV and V. During encystment, the body diminishes and becomes globular, the nuclear apparatus is reorganized, and the ciliature is resorbed. In our molecular phylogenies, the family Kahliellidae is polyphyletic and the position of K. matisi is rather poorly resolved, indicating a relationship with oxytrichids.
研究了一种新的土壤寡毛类纤毛虫 Kahliella matisi 的形态、个体发生、胞囊形成和 18S rRNA 基因序列。K. matisi 的主要特征为：（1）口围带区右侧有两短六长的纤毛列，左侧有四长列；（2）有三个背腹联纤毛列，其中 1 列沿左侧胞缘延伸，2 列呈轻微的“S”形，3 列在后部明显缩短。个体发生与近缘种相似，尤其是在缘纤毛列和长背腹联纤毛列的发育、分裂后一些旧的纤毛列的保留以及新动体联纤毛列的方向方面。但也有一些特殊之处：（1）亲代口围带纤毛的重组；（2）口部后纤毛列 II 的分裂成 II 和 III；（3）来自 IV 和 V 的原基形成亲代纤毛列 R3。在胞囊形成过程中，虫体缩小并呈球形，核器重新组织，纤毛消失。在我们的分子系统发育中，Kahliellidae 科是多系的，而 K. matisi 的位置分辨率较差，表明与氧纤毛类关系密切。
