The morphology, infraciliature and small subunit ribosomal RNA gene-based phylogeny of an urostylid ciliate, Monocoronella carnea n. g., n. sp., found in coastal areas off Daya Bay, Southern China, were investigated. The new genus Monocoronella n. g. is recognized by the following features: having conspicuous frontal cirri forming a long and single corona; buccal and frontoterminal cirri present; single marginal row on each side; adoral zone, midventral complex and transverse cirri in Pseudokeronopsis mode. The type species M. carnea n. sp. is diagnosed by the combination of marine habitat and brown-reddish color of the cortical granules. Phylogenetic analyses for the new taxon indicate that Monocoronella n. g. is most closely related to Bergeriella, and is located within the core Urostylida clade. A misidentification in previous literature was recognized and a new species, Monocoronella dragescoi n. sp. [Basionym: Holosticha (Keronopsis) monilata (Kahl 1928) sensu Dragesco (1970) et sensu Dragesco and Dragesco-Kernéis (1986), non sensu Kahl (1928)], was suggested.
对在中国南部大亚湾沿海地区发现的一种后口目缘毛目纤毛虫，Monocoronella carnea n. g.，n. sp. 的形态、纤毛结构和小亚基核糖体 RNA 基因系统发育进行了研究。新属Monocoronella n. g. 的特征为：具有明显的额前纤毛，形成长而单一的冠状物；具有口前纤毛和额前纤毛；每侧有单一的边缘纤毛列；具有伪尾柱目式的口前区、中腹复杂结构和横纤毛。模式种M. carnea n. sp. 的诊断特征为海洋生境和皮质颗粒的棕红色。对新分类群的系统发育分析表明，Monocoronella n. g. 与Bergeriella 最为密切相关，位于核心后口目类群内。先前文献中的一个误鉴定得到了确认，并提出了一个新种，Monocoronella dragescoi n. sp. [原名：Holosticha (Keronopsis) monilata (Kahl 1928) 感 Dragesco (1970) et sensu Dragesco 和 Dragesco-Kernéis (1986)，非 Kahl (1928) 原意]。
