We report herein three epibiotic associations between peritrich ciliate protozoans and polychaete worms, as observed in Tamilnadu, southeastern coast of India. Epibiont ciliates Epistylis sp.1 were found all over the integument of individuals of the terebellid polychaete Terebella sp., collected from Vellar estuary. Epistylis sp.2 ciliates were observed attached to Namalycastis abiuma polychaetes, on both sides of parapodia. Cothurnia sp. ciliates were found on anterior most paleae and hooks of Sabellaria sp. polychaetes, both latter associations from material from the Uppanar estuary. Those epibiont/basibiont associations are all new to science and discussed herein, together with a review on the previous reports of epibiont ciliate protozoans in Indian waters.
我们报告了在印度东南部泰米尔纳德邦观察到的三种缘毛目纤毛虫原生动物与多毛环节蠕虫的共生关系。在采集自维拉尔河口的 terebellid 多毛类 terebella sp.个体全身都发现了共生纤毛虫 Epistylis sp.1。在 Namalycastis abiuma 多毛类动物的体节两侧观察到了附着的 Epistylis sp.2 纤毛虫。在采集自 Uppanar 河口的 Sabellaria sp.多毛类动物的前最鳞片和钩上发现了 Cothurnia sp.纤毛虫。这些共生体/基础体共生关系对科学来说都是全新的，本文对此进行了讨论，并回顾了印度水域中以前报道的缘毛目纤毛虫原生动物共生关系。
