Abstract: In an attempt to map the digenetic trematode fauna of the frogs of Western Ghats, India as a part of a major research project, we came across the metacercaria of a trematode parasite, Encyclometra colubrimurorum (Rudolphi, 1819) Dollfus, 1929 infecting the liver, obliquus externus muscle and head of an adult frog, Fejervaria sp. (Anura, Dicroglossidae) and liver of a tadpole of the bicoloured frog, Clinotarsus curtipes (Jerdon, 1853) (Anura, Ranidae), collected during January 2016 to October 2017. Metacercaria has oval to round cyst with thin, transparent wall. Excysted metacercaria has fusiform, aspinose body with oval, subterminal oral sucker and equatorial acetabulam. Caeca was long, asymmetrical, unequal and extend almost up to posterior end of body. This paper is the first report of E. colubrimurorum metacercaria from the frog hosts, C. curtipes and Fejervaria sp. The prevalence of infection in C. curtipes was 25% and the intensity of infection was six. In Fejervaria sp. the prevalence of infection was 2.2% and the intensity of infection was 1.5. Although the metacercaria of E. colubrimorarum was reported earlier their morphological descriptions were not properly recorded. In this paper the morphology of the trematode metacercaria is described.
