对一种与Urostyla grandisEhrenberg（Urostyla模式种）高度相似的次毛纤毛虫菌株进行了间期标本、生理重组和分裂形态发生方面的研究，该纤毛虫是从南帕拉伊巴河（巴西里约热内卢）河口的红树林地区采集的。结果显示，尽管是间期标本，但与 U 中已知的形态变异相匹配。巨观，形态发生过程有明显的差异。亲本口区在形态发生过程中完全更新，边缘纤毛表现出独特的发育模式组合，其中左边缘行起源于最内侧左边缘卷曲行的多个原基，而右边缘纤毛起源于单个行内原基。基于这样的特征，一个新的亚种，即U。伟科斯基亚种十一月被提议，因此，U。埃伦伯格，统计数据。十一月成立。明确放置的 18S rDNA 的贝叶斯和最大似然分析。由 otherU 形成的簇的 grandis wiackowskiias adelphotaxon。宏大的序列。讨论了这些发现对尾柱系统学的影响。
Interphase specimens, aspects of physiological reorganization and divisional morphogenesis were investigated in a strain of a hypotrichous ciliate highly similar toUrostyla grandisEhrenberg, (type species ofUrostyla), collected from a mangrove area in the estuary of the Paraíba do Sul river (Rio de Janeiro, Brazil). The results revealed that albeit interphase specimens match with the known morphologic variability inU. grandis, morphogenetic processes have conspicuous differences. Parental adoral zone is entirely renewed during morphogenesis, and marginal cirri exhibit a unique combination of developmental modes, in which left marginal rows originate from multiple anlagen arising from innermost left marginal cirral row, whereas right marginal ciliature originates from individual within‐row anlagen. Based on such characteristics, a new subspecies, namelyU. grandis wiackowskiisubsp. nov. is proposed, and consequently,U. grandis grandisEhrenberg, stat. nov. is established. Bayesian and maximum‐likelihood analyses of the 18S rDNA unambiguously placedU. grandis wiackowskiias adelphotaxon of a cluster formed by otherU. grandissequences. The implications of such findings to the systematics ofUrostylaare discussed.
