First record of Henricia reniossa reniossa Hayashi, 1940 (Spinulosida: Echinasteridae) from central Honshu, Japan

Abstract

Henricia reniossa reniossa was first discovered on the coast of Honshu Island, Japan, extending the southern limit of this subspecies to central Japan. This finding suggests that the distributional range of the two subspecies of Henricia reniossa presumably overlapped. Herein, we describe the morphology of Henricia reniossa reniossa with brief comments regarding its subgeneric classification of Henricia reniossa.
