Abstrakt: 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. possess pseudosuckers and lack the paraprostate, otherwise extremely characteristic of the Proterodiplostomidae Dubois, 1936. In the present study, we describe the morphology of progenetic metacercariae of a Proalarioides sp. from bicolored frog, Clinotarsus curtipes (Jerdon), collected in India and provide the first DNA sequences from any member of the genus. These specimens differ from previously described metacercariae and adults of P. serpentis and P. tropidonotis in several ways, including body and organ sizes, sucker ratios, and distribution of vitellarium. The newly generated partial large ribosomal subunit (28S) rRNA gene sequence was used to test the phylogenetic position of the genus among other major lineages of diplostomoideans. Our 28S phylogeny clearly demonstrated Proalarioides sp. to be well-separated from other members of the Proterodiplostomidae. Based on morphological and molecular evidence, we transfer Proalarioides out of the Proterodiplostomidae into the Diplostomidae Poirier, 1886.
