Five species of suctorian ciliates belonging to four different genera attached to meiofaunal organisms of Maldivian archipelago (Suvadiva Atoll) were documented. Three rare species (Acineta sp., Thecacineta urceolata Liao & Dovgal, 2015 and Limnoricus ceter Jankowski, 1981) and one common suctorian ciliate Thecacineta calix (Schröder, 1907) are re-described from nematodes (Croconema cinctum Cobb, 1920, Desmodorella tenuispiculum Allgén, 1928 and Desmodora sp.) and harpacticoid copepod basibionts. In addition, Trophogemma colantonii n. sp. colonizing the abdomen and legs of the harpacticoid copepod Stenhelia sp. is described. The new species differs from the relative species for the less flattened cell body, the absence of both lateral bundles of tentacles and separate lateral tentacles as well as for the presence of longitudinal ribs along the cuticle. The data obtained in this survey give not only new important information on the taxonomy and distribution of Suctorea, but also new insights on their relationship with meiofaunal organisms in one of the most diverse and productive marine micro-habitat of carbonate sediments.
记录了隶属于四个不同属的五种吸管虫纤毛虫，它们附着在马尔代夫群岛（苏瓦迪瓦环礁）的小型底栖生物上。从线虫（1920年的Cobb环纹克罗线虫、1928年的Allgén细刺小线虫和Desmodora属线虫）和猛水蚤类桡足类宿主上对三种稀有物种（Acineta属物种、2015年廖和多夫加尔发现的瓶状鞘吸管虫以及1981年扬科夫斯基发现的中央吸管虫）和一种常见的吸管虫纤毛虫杯状鞘吸管虫（施罗德，1907年）进行了重新描述。此外，还描述了一种定殖于猛水蚤类桡足类Stenhelia属物种腹部和腿部的新物种——科兰托尼滋养吸管虫。该新物种与相关物种的区别在于其细胞体较不扁平，没有侧触手束和单独的侧触手，以及在角质层上有纵向肋条。本次调查获得的数据不仅为吸管虫纲的分类学和分布提供了新的重要信息，也为它们在碳酸盐沉积物中最多样化和生产力最高的海洋微生境之一中与小型底栖生物的关系提供了新的见解。
