"Polypedates leucomystax","Japan","Transmission of disease","MN","Raillietnema rhacophori and Allodero sp. were considered to have reached this island by accompanying P. leucomystax from the Central Ryukyus. [...] From a total of 42 individuals of P. leucomystax examined (33 males and eight females, 39?70 mm [mean=51.9 mm] in snout-vent length), eight helminth species, i.e., one digenean, five nematodes, one acanthocephalan, and one oligochaete, were recognized [...] Kuraishi et al. (2009) demonstrated on the basis of mitochondrial cytochrome b gene sequence data that the current Ryukyu populations of P. leucomystax were originated from a limited number of individuals that had been artificially transported from the Philippines. If R. racophori and Allodero sp. had also been introduced through this initial introduction by accompanying P. leucomystax, the Philippine populations of this frog must have these helminths, predicting actual prevalence of these parasites in the Philippine frogs.","Low","Transmission of parasite not shown directly, but some parasites also found in native species.

"Polypedates leucomystax","Japan","Transmission of disease","MN","The prevalence and intensity of helminth infections in P. leucomystax on Ishigakijima and Iriomotejima are shown in Table 1 in comparison with those previously recorded on Okinawajima and Miyakojima and with those of the endemic frogs. One digenean, eight nematode, two acanthocephalan, and one oligochaete species were found from P. leucomystax.[...] Allodero sp. showed much higher prevalence in P. leucomystax than the other endemic frogs on Okinawajima. (Hasegawa, 1993b, 1994). We believe that this oligochaete was introduced to Okinawajima from the Southeast Asian region by P. leucomystax,
though the possibility cannot be completely excluded that it was originally an endemic parasite of Okinawan amphibians or its freeliving stage was introduced from a foreign country with soil or plants.","Low","Some parasites also found in native frogs, but others not found.","Not specified","Hasegawa H, Kadota Y, Ikeda Y, Sato A, Matsuura K (2018) Helminth Parasites of Polypedates leucomystax (Amphibia: Rhacophoridae) in Yaeyama Islands, Southern Ryukyu, Okinawa, Japan.
