A new species of the genus Neostylodactylus Hayashi & Miyake, 1968 (Crustacea: Decapoda: Stylodactylidae) from southern Japan

摘要

A new species of stylodactylid shrimp, Neostylodactylus litoralis, is described and illustrated on the basis of four ovigerous females collected from sublittoral zones on the Ogasawara and Ryukyu Islands at depths of 3-10.5 m. This new species is readily distinguished from the five described species of Neostylodactylus Hayashi & Miyake in having a non-produced posterior margin of the telson, the noticeably elongate mesialmost pair of posterior spines on the posterior margin of the telson, and unarmed meri of the third to fifth pereiopods.
