南极洲是一个偏远且孤立的生境，这使其成为研究新特有物种的理想地点。由于有关该地区纤毛虫多样性的文献很少，2006年1月至3月对乔治王岛柯林斯冰川融水中的纤毛虫进行了分类学调查。结果，通过现场观察和银染技术描述了五种纤毛虫的形态和脆弱性，其中包括一个新物种：Gastronauta multistriatanov。规格，Neokeronopsis asiaticaFoissner 等，2010，Paraholosticha muscicolaKahl，1932，Oxytrichasp.，和 Cyclidium glaucomaMüller，1786。Gastronauta multistriatanov。规格通过以下特征组合区别于其同类物：体内细胞大小平均为 80 × 40 μm；左侧睫状体区域有 5-9 个运动；右睫状体有 18-23 个运动，包括 10-12 个后部运动； 7-10 个口前运动；背刷沿背前缘，由5-8组基体组成。当前 N 种群之间唯一的细微差别。 asiatica 和先前描述的南极种群的数量是尾部 cirri（6-10 与 8-15）和背侧运动（11-13 与 12-18）的数量。Paraholosticha sterkiiis 与 P. asiatica 同义词。 muscicola.C的南极种群。青光眼与中国以前的人群非常吻合，唯一的区别是 SKn 中的动体数量（11-17 与 9-11）。这项工作将有助于了解这个小研究领域的纤毛虫多样性。
Antarctica is a remote and isolated biotope which makes it an ideal location for studying new and endemic species. Since there is little literature available on the diversity of ciliates in this area, a taxonomic survey of ciliates from melt-water of Collins glacier, King George Island, was carried out from January to March 2006. As a result, the morphology and infraciliature of five ciliates, including one new species, are described using live observations and silver staining:Gastronauta multistriatanov. spec.,Neokeronopsis asiaticaFoissner et al., 2010,Paraholosticha muscicolaKahl, 1932,Oxytrichasp., andCyclidium glaucomaMüller, 1786.Gastronauta multistriatanov. spec. is distinguished from its congeners by the following combination of characters: cell size in vivo on average 80 × 40 μm; 5–9 kineties in left ciliary field; 18–23 kineties in right ciliary field, including 10–12 postoral kineties; 7–10 preoral kineties; dorsal brush along anterior dorsal margin, consisting of 5–8 groups of basal bodies. The only minor differences between the current population ofN. asiaticaand a previously described Antarctic population are the numbers of caudal cirri (6–10 vs. 8–15) and dorsal kineties (11–13 vs. 12–18).Paraholosticha sterkiiis synonymised withP. muscicola.The Antarctic population ofC. glaucomacorresponds well with a former population from China, the only difference being the number of kinetids in SKn(11–17 vs. 9–11). This work will contribute to the understanding of ciliate diversity in this little studied area.
