備考 Remarks

Polystoma ozakii Uchida, Machida, Uchida and Itagaki, 1988 は P. ozakii Price, 1939の新参同名であり，かつ Goldberg and Bursey (2002) によって P. integerrimumの新参異名とされている．その後，du Preez et al. (2023) 本種を独立種とみなし，置換名 Polystoma uchidai  を提唱した．

Polystoma ozakii Uchida, Machida, Uchida and Itagaki, 1988 is a junior homonym of P. ozakii Price, 1939 and regarded as a junior synonym of P. integerrimum by Goldberg and Bursey (2002). Subsequently, du Preez et al. (2023) considered this species to be independent and proposed the replacement name, Polystoma uchidai.
