在墨西哥凤梨科植物Tillandsia heterophylla的池中发现了凤梨coterillia bromelicola 11 . gen., 11 . specia。用标准方法对其形态、个体发生和18S rDNA进行了研究。黄萎病在身体两侧有许多环状排列。它的独特之处在于，它具有从头开始的背部运动，产生新的运动波，其中亲本背部运动重组为“组合行”，由前面的背刚毛和后面的卷毛组成。因此，长达四代的刚毛和卷毛出现在体背表面。凤梨黄萎病菌体呈淋口状，有胞膜带，纤毛浓密，神经波似蜂窝状下毛。然而，对样本1的从头起源和分子分析令人信服地表明，Cotterillia属于淋虫科，这为改进诊断提供了依据。因此，神经神经波独立地产生了好几次。与Trachelostyla、Gonostomum和Cotterillia不同的形态和成因相比，它们之间的分子差异很小（≤5%），这表明18S rDNA低估了它们的属多样性。我们的研究强调需要结合形态学、个体发生和分子研究来解开欠营养纤毛虫的复杂系统发育和进化。
Cotterillia bromelicola nov. gen., nov. spec. was discovered in the tanks of the Mexican bromeliad Tillandsia heterophylla. Its morphology, ontogenesis, and 18S rDNA were studied with standard methods. Cotterillia has many cirral rows on both sides of the body. Uniquely, and thus used to diagnose the new genus Cotterillia, it has dorsal kineties originating de novo, producing neokinetal waves where the parental dorsal kineties reorganize to “combined rows”, consisting of dorsal bristles anteriorly and of cirri posteriorly. Thus, up to four generations of bristles and cirri occur on the dorsal body surface. Cotterillia bromelicola has a gonostomatid body and adoral zone of membranelles, while the dense ciliature and the neokinetal waves resemble kahliellid hypotrichs. However, the de novo origin of anlage 1 and the molecular analyses show convincingly that Cotterillia belongs to the Gonostomatidae , for which an improved diagnosis is provided. Thus, neokinetal waves originated several times independently. The molecular differences between Trachelostyla, Gonostomum, and Cotterillia are small (≤5%) compared to their distinct morphologies and ontogeneses, suggesting that the 18S rDNA underestimates generic diversity. Our study emphasizes the need of combined morphological, ontogenetic, and molecular investigations to unravel the complex phylogeny and evolution of hypotrich ciliates.
