Abstract
A new chirostylid crustacean, Chirostylus stellaris, is described from the Ryukyu Islands, southwestern Japan. The new species is morphologically close to C. ortmanni Miyake & Baba, 1968, but distinguishable by the armature of the meri of the male first pereopods and the proportion of lengths relative to the heights of the propodi of the second to fourth pereopods. The live coloration of the pereopods is also clearly different in the two species. Chirostylus ortmanni is described on the basis of specimens from various localities in Japan, to complement the original account of the species
