On two new species of Mehraorchis Srivastava, 1934 (Digenea: Pleurogenidae) infecting frogs of the South Western Ghats, India

Abstract

Two new species of digenetic trematodes of the genus Mehraorchis infecting the freshwater frogs, Euphlyctis cyanophlyctis and Hoplobatrachus tigerinus inhabiting the South Western Ghats, India, are described with illustrations and details on the prevalence, intensity and mean abundance of infection of Mehraorchis janardanii n. sp. and Mehraorchis euphlycti n. sp. are added. M. janardanii n. sp. and M. euphlycti n. sp. are differentiated from other Mehraorchis species based on the differences in their morphology and morphometry. The prevalence of M. janardanii n. sp. in E. cyanophlyctis is 1.29%, the intensity is 13 and the mean abundance is 0.16. The prevalence of infection of M. euphlycti n. sp. in E. cyanophlyctis is 0.64% and in H. tigerinus 6.06%, the intensity of infection is one in both the hosts and the mean abundance is 0.006 and 0.06, respectively.
