Proterodiplostomid no longer: Molecular phylogeny reveals the true position of Proalarioides (Digenea: Diplostomoidea).

Proalarioides Yamaguti, 1933 (Digenea Carus, 1863: Diplostomoidea Poirier, 1886) is a small genus of proterodiplostomids parasitic in the intestines of snakes in Asia. Only two species are considered valid: Proalarioides serpentis Yamaguti, 1933 and Proalarioides tropidonotis Vidyarthi, 1937. Unlike other proterodiplostomids, Proalarioides spp.

Phylogenetic relationships of two species of Haematoloechus (Trematoda: Haematoloechidae) infecting Euphlyctis spp. from the biodiversity hotspot, Western Ghats, India.

During a parasitological survey in the biodiversity hotspot, two species of the digenetic trematode, Haematoloechus from the lungs of Indian skipper frog Euphlyctis cyanophlyctis and the Indian green frog, E. hexadactylus inhabiting the biodiversity hotspot, Western Ghats, India, were found and described using morphological and molecular tools. Morphological examinations indicated that the two species are Haematoloechus almorai Pande, 1937 and H.

Chelatrematidae n. fam., a new family of digenetic trematodes from the South Western Ghats, India, erected on the basis of morphological and molecular studies.

On the basis of the morphological characterization of Manjula & Janardanan, 2006 recovered from the freshwater fish (Valenciennes, 1844) in the Wayanad region of the Western Ghats, the diagnostic features of the genus Gupta & Kumari, 1973 have been modified. Based on the phylogenetic analysis of and comparative morphology studies relative to members of other families of Gorgoderoidea Looss, 1901, this genus is placed in a new family Chelatrematidae n. fam.

Distribution of different species of metacercariae in two freshwater fishes: (Teleostei: Cyprinidae) and (Teleostei: Osphromenidae).

Information on the distribution and abundance patterns of trematodes are essential to reveal the ecology of host-parasite interactions. The Western Ghats of India, a biodiversity hotspot, is rich in freshwater fish diversity and endemism. Though there are several studies on various other aspects of fish ecology, studies on their parasitic fauna is meager.

Further contribution to the life history of Centrocestus formosanus (Nishigori, 1924) Price, 1932 (Trematoda: Heterophyidae) with special reference to a new first intermediate host from the South Western Ghats, India.

Centrocestus formosanus is a zoonotic small invasive heterophyid fluke with worldwide distribution. Its three-host life cycle requires a thiarid snail as first intermediate host, fishes as second intermediate hosts and piscivorous birds and mammals as definitive hosts for completion. As far as is known, the only first intermediate host being utilized, globally, by this parasite is the snail, Melanoides tuberculata.
