( Table 4 ) Synonym: Polystoma rhacophori Yamaguti, 1936 [ 53 ]. Type-host: Rhacophorus schlegelii var. arborea Okada. Now Zhangixalus arboreus (Okada and Kawano) [ 21 ]. Site: Bladder. Type-locality: Kurama, near Kyoto , Japan . Remarks: Although the author of the original description did not draw the marginal hooklets [ 53 ], the general morphology of this species, including hamuli shape (unbranched), is consistent with the diagnosis of Indopolystoma . The haptor/ total body length ratio of about 0.18 is bigger than that of any other Indopolystoma spp. with the exception of I. zuoi (Shen, Wang & Fan, 2013) n. comb. As discussed earlier for I. elongatum , which infests the same host, we consider for now that both I. elongatum and I. rhacophori are two separate species primarily on the basis of body length and haptor/ total body length ratio.
