Hypotrichs是最复杂和高度分化的纤毛虫谱系，具有很大的潜力，为进化的新奇。下毛类系统学中存在的问题主要是由于形态学和遗传学数据（主要是小亚基rRNA基因）之间的不一致。具有两个或两个以上更高级别分类群的形态特征的物种可能是这些冲突的主要促成因素。本研究描述了一个中国人口的一个鲜为人知的有机体与众多的内共生zochlorellae，其形态对应以及模式人口的Limnoholosticha viridis。新获得的信息表明，该物种有一个曲折的midventral卷须模式，是诊断urostylids，而背纤毛的股票功能（存在dorsomarginal kinety和背kinety 3碎片）是典型的oxytrichids。分子系统发育分析揭示了与尖毛类的密切关系。综合形态学、形态发生学、系统发育学和生态学的研究结果表明，L. viridis代表一个新属新科，可能是uorstylids和dorsomatrialians之间的一个中间类型。因此，Bourlandellidae fam. nov.和Bourlandella gen. nov.在此建立。最后，我们推测表型趋同和混合营养可能会产生新组合Bourlandella viridis comb. nov.，适应各种环境条件的能力。
Hypotrichs are the most complex and highly differentiated ciliate lineages and have great potential for evolutionary novelties. Problems in hypotrich systematics are mainly due to discordance between the morphological and genetic data (mainly small subunit rRNA gene). Species with morphologies that are characteristic of two or more higher rank taxa are probably a major contributing factor to these conflicts. The present study describes a Chinese population of a poorly known organism with numerous endosymbiotic zoochlorellae, the morphology of which corresponds well with the type population of Limnoholosticha viridis. Newly obtained information shows this species has a zigzag midventral cirral pattern that is diagnostic of urostylids, whereas the dorsal ciliature shares features (presence of dorsomarginal kinety and dorsal kinety 3 fragmentation) that are typical of oxytrichids. Molecular phylogenetic analyses reveal a close relationship with oxytrichids. An integrative approach combining morphological, morphogenetic, phylogenetic and ecological analyses indicates that L. viridis represents a new genus and new family which might be an intermediate form between uorstylids and dorsomarginalians. Thus, Bourlandellidae fam. nov. and Bourlandella gen. nov. are here established. Lastly, we speculate that phenotypic convergence and mixtrophy might confer on the new combination, Bourlandella viridis comb. nov., the ability to adapt to a wide range of environmental conditions.
