A Neoheterocotyle Species First Found in Japan

Authors:Imogen Chapman

Abstract


During a study of the monogeneans of Rhinobatos hynnicephalus Richardson, 1846 (Rhinopristiformes: Rhinobatidae) collected from the central Seto Inland Sea, Hiroshima Prefecture and the southern Sea of Japan, Fukuoka Prefecture, one undescribed species of Neoheterocotyle was found. In the present paper, the new species is described with a molecular information. This is the first report of a Neoheterocotyle species from Japan. The new species are most similar in morphology to Nepenthes fragilis and N. rhinoceros. They have two pairs of dorsal parascleral sclera, but they differ in that the penis is curved proximally and the accessory teeth have a blade-like process.
