Abstract

We describe Cruranthura viridis sp. nov. based on four specimens collected from the subtidal zone near Irabu Island, Miyako Islands, Okinawa, Japan. This species differs from four congeneric species in having (1) small body size (2.53–3.38 mm), (2) moss green body color, (3) eyes, (4) pleonite 1 longer than pleonite 2, (5) telson length 2.06–2.33 times telson width, (6) propodus of pereopod 1 with 6–10 inner spiniform setae, and (7) the endopods of pleopods 2–5 uniarticulate, with plumose setae. We also determined the partial sequence of the cytochrome c oxidase subunit I (COI) gene from the holotype specimen. We discuss differences in piercing mouthparts among paranthurid genera.
