摘要：
During two expeditions to Caroline Plate seamounts and Zhenbei seamount in the NW Pacific, three Paralebbeus (we list Paralebbeus as a synonym of Lebbeus herein) specimens are sampled. Two of them are recognized as new to science herein after carefully morphological observations. L. cultrirostris sp. nov. collected with the keratoisidid coral at a depth of 866 m is characterized by the smooth rostrum, and the telson having three pairs of dorsolateral spines. L. kexuei sp. nov. collected at a depth of 796-1510 m is characterized by the rostrum only bearing two dorsal spines, and the carpus of pereopod 2 having two articles equal in length. Morphological characters and generic analysis of mitochondrial COI and 16 S rRNA genes using maximum likelihood, Bayesian inference, and pairwise uncorrected p-distances indicated that all species of Paralebbeus Bruce and Chace (1986 should be transferred into genus Lebbeus White, 1847.
