Introduction

Faubel (1984) considered Amakusaplana Kato, 1938 to be a junior synonym of Prosthiostomum Quatrefages, 1845. Prudhoe (1985) also noted the similarity of Amakusaplana to Prosthiostomum, however, he maintained the validity of the genus. Genetic analyses conducted by Litvaitis et al. (2019) placed Amakusaplana acroporae in Prosthiostomum with strong support; they proposed Amakusaplana be synonymised with Prosthiostomum.
