Abstract：
This paper provides the first detailed description of a Tetracapsuloides species, Tetracapsuloides vermiformis n. sp., with vermiform stages in the bryozoan host, Fredericella sultana, and its experimental transmission from F. sultana to Cyprinus carpio. The suitability of morphological, biological and 18S rDNA sequence data for discrimination between malacosporean species is reviewed and recommendations are given for future descriptions. Presently, malacosporean species cannot be differentiated morphologically due to their cryptic nature and the lack of differential characters of spores and spore-forming stages in both hosts. We examined biological, morphological and molecular characters for the present description and for revising malacosporean taxonomy in general. As a result, Buddenbrockia plumatellae was split into two species, with its sac-like stages being ascribed to Buddenbrockia bryozoides n. comb. In addition to ribosomal DNA sequences multiple biological features rather than morphological characters are considered essential tools to improve malacosporean taxonomy in the future according to our analysis of the limited traits presently available.
摘要：
本文提供了对四聚类物种的第一个详细描述，虎尾草。,苔藓虫宿主中的蠕虫状阶段，苏丹弗雷德里克氏菌，以及它从F.sultana到鲤鱼的实验性传播。形态学的适用性，审查了用于区分malacosporean物种的生物学和18SrDNA序列数据，并为将来的描述提供了建议。目前,由于它们的隐蔽性以及两个宿主中孢子和孢子形成阶段缺乏差异特征，因此无法在形态上进行区分。我们检查了生物，本说明书的形态和分子特征以及一般用于修订malacosporean分类学的特征。因此,布登布洛克被分为两个物种，其囊状阶段归因于布丁布洛克草。梳子。根据我们对目前可用的有限性状的分析，除了核糖体DNA序列外，多种生物学特征而不是形态特征也被认为是将来改善malacosporean分类学的重要工具。
