n. sp. (Digenea, ) from the intestine of the water skipper, (Anura, Dicroglossidae), inhabiting the Western Ghats, India is described and illustrated. n. sp. is new to the genus and is separated from its congeners on the basis of differences in morphology and morphometry. It is named after the host,.

Two new species of digenetic trematodes of the genus infecting the freshwater frogs, and inhabiting the Western Ghats, India are described and illustrated. n. sp. and n. sp. are separated from their congeners on the basis of differences in the morphology and morphometry. The prevalence of infection of n. sp. in is 8.99% and in 12.5% and the intensity is 6.5 and 7.0 respectively. Prevelance of n. sp. in. is 4.49% and in 6.25% and the intensity is 11.25 and 6 respectively. Since trematode parasites have complex life cycles, with multiple hosts that follow trophic level transfer, the parasite larvae may serve as reliable indicators of species diversity in an ecosystem.

Four species of digenean parasites, Ganeo glottoides, Pleurogenoides cyanophlycti, Tremiorchis ranarum and Encyclometra colubrimurorum infecting the frog Fejervarya sp. (Anura: Dicroglossidae) of the Wayanad Region of the South Western Ghats are reported in this paper. Of the trematode parasites recovered, three, G. glottoides, P. cyanophlycti and T. ranarum, were adults and one, E. colubrimurorum, a metacercaria. Multiple infections were also recorded during the study. Prevalence of infection of G. glottoides, P. cyanophlycti, T. ranarum and E. coloubrimurorum were 1.27%, 0.84%, 0.84% and 0.84%, respectively, the intensity of infection 5, 1, 4.5 and 1.5 and the mean abundance 0.063, 0.008, 0.038 and 0.012, respectively. Mean abundance is a clear indication of the dispersion of parasites among hosts. The mean abundance, prevalence of infection and the intensity were at the maximum level in G. glottoides infection.

Three species of digenean parasites, Pleurogenoides euphlycti, P. wayanadensis and Meharorchis ranarum of the frog Hoplobatrachus tigerinus (Anura, Dicroglossidae) from the Wayanad Region of the South Western Ghats are reported in this paper. Multiple infections were also recorded during the study. Prevalence of infection of P. euphlycti, P. wayanadensis and M. ranarum were 15.15%, 9.09% and 12.12%, respectively, and the intensity of infection were 5.2, 7.3 and 8, and the mean abundance were 0.78, 0.66 and 0.96, respectively. Mean abundance is an indication of the dispersion of parasites among hosts. The mean abundance and the intensity were at the maximum level in M. ranarum infection and that of prevalence of infection was at the maximum level in of P. euphlycti infection.
