Description of a New Genus of Candimboididae (Polycladida: Acotylea) from the Coast of Sagami Bay

Abstract

We establish a new genus of candimboidid polyclad, Chimaeriplana gen. nov., based on a new species, C. japonica sp. nov., collected from Kanagawa, the coast of Sagami Bay, Japan. Chimaeriplana japonica sp. nov. is characterized by (i) an interpolated prostatic vesicle with a seminal vesicle, (ii) a penis stylet with a split tip, (iii) numerous prostatoid organs in the male atrium, (iv) a bursa copulatrix, and (v) without Lang’s vesicle. In addition, we modify the definition of Candimboididae.
