Dovgal et al. (2009a) reported this species on the nematode Pseudochromadora sp. from Ratnagiriı Maharastra Stateı central west coast of India (Arabian Sea).

Based on the figure given by Fisher (2003) ı found at nematode Pseudochromadora cazca Gerlachı 1956 ı from the intertidal zone of North-Eastern Queenslandı Australia Dovgal et al. (2009a) identified these ciliates ‘probably as Trematosoma rotunda (Allgénı 1952) ’.

Bhattacharjee (2014) reported the same species on the nematode host Chromaspirina sp from Rushikulya ( Odisha State of India)ı north-western Bay of Bengal in the Indian Ocean.

Ansari and Bhadury (2016) reported this species on the nematode Dorylaimopsis punctata Ditlevsenı 1918 from Sagar Islandı Sundarban mangrove ecosystemı Indiaı Bay of Bengal.

Ghosh and Mandal (2019) reported this species as epibiont on Desmodora scaldensis de Man 1889 from the subtidal zone of Matla estuaryı Sundarbanı India.
