摘要
本工作采用Chatton-Lwoff氏银浸法及Wilbert氏蛋白银染色法研究了淡水纤毛虫暗尾丝虫Uronema nigricans(Muller,1786)的形态、核器、纤毛下器、银线系及详细的形态发生过程。结果显示其口器发生与已知的同属种类海洋尾丝虫具相似的过程及形式。其口器发生及演化的基本模式可表达成: 前仔虫:原口侧膜→口侧膜,盾片; 后仔虫:原口侧膜→口侧膜,第1小膜,第2小膜,盾片; 原盾片→第3小膜。 文中另外列表比较了本属与其它属的形态发生特征,并据此建立了一新科,拟梭虫科。
The present paper deals with studies on the morphology, infraciliature, silverline system and the morphogenesis of the fresh-water scuticociliate Uronema nigricans. The characteristics of several known species of the genus are biometrically tabled.In the light of the development of its infraciliature and nuclei, 11 morphogenctic stages are described. The buccal ontogeny of U- nigricans can be expressed as follows:for the proter: PM→PM, Sc; for the opisthe: PM→ PM,M1,M2;Sc; Sc→M3 The results demonstrate that the stomatogenesis of this species (genus) is very similar to that of Parauronema and Philasterides.Based on the morphogenetic features some scuticociliates are discussed (Tab. 3). According to that, a new family, Paralembidae nov. fam. is established.
