Abstract
A new species of Neoferdina is described under the name of Neoferdina japonica from Kushimoto, Wakayama Pref., Japan. This species is related to N. ocellata (H. L. CLARK) and N. insolita LIVINGSTONE. However, it is separable from the former by the shape and arrangement of superomarginal plates and from the latter by the shape and granulation of the first superomarginal plate.
