Two new species of hippolytid shrimp, Lebbeus elegans sp. nov. and L. polyacanthus sp. nov., are described from the Sea of Japan, at depths of 250-400m. Lebbeus elegans is characterized by the absence of epipods on the second and third pereopods, distinct ventral blade of the rostrum and the rounded fourth abdominal pleuron. Lebbeus polyacanthus is compared with L. antarcticus (Hale, 1941), L. carinatus Zarenkov, 1976, and L. washingtonianus (Rathbun, 1902). Lebbeus polyacanthus differs from the latter three species in the more posteriorly arising posteriormost tooth of the dorsal rostral series and more numerous lateral spines on the meri of the third to fifth pereopods. Examination of the newly obtained material of L. kuboi Hayashi, 1992, enabled us to assess intraspecific variations of the species, including a variation in the development of the pereopodal epipods. Redescription of Lebbeus kuboi is provided and its affinity is discussed. These three species occur sympatrically. A brief note on the taxonomy and distribution of species of Lebbeus is also provided.
