Indopolystoma rhacophori (Yamaguti, 1936), 2019

Chaabane, Amira, Verneau, Olivier & Preez, Louis Du, 2019, Indopolystoma n. gen. (Monogenea, Polystomatidae) with the description of three new species and reassignment of eight known Polystoma species from Asian frogs (Anura, Rhacophoridae), Parasite (Paris, France) 26 (67), pp. 1-18 : 15

Indopolystoma rhacophori (Yamaguti, 1936)

n. comb. (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.
