ABSTRACT. A new species of the genus Onycocaris, O. temiri sp.n., is described from Nha Trang Bay, South Viet Nam. The new species is associated with shallow-water sponges of the genus Kallipilidion extracted from dead coral rocks. This is the first record of this genus from Vietnamese waters. Morphologically, the new species is closely related to O. profunda Bruce, 1985 and O. seychellensis Bruce, 1971, collected from the Philippines, at depth of 81–84 m and the Seychelles, at a depth of 0.5 m, respectively. The new species is recognized by the form of the proximal segment of the antennules, dentition of dactyli of the second pereiopod and, especially by the pointed posterior margin of the telson.
KEY WORDS: Onycocaris, new species, Viet Nam.
