The present study deals with a collection of deep-sea shrimp of the pandalid genus Pandalopsis Spence Bate, 1888 from the Nemuro Strait, Hokkaido, southwestern part of the Sea of Okhotsk. Three new species are described and illustrated: Pandalopsis capillus n. sp., P. houyuu n. sp. and P. princeps n. sp. In addition, Pandalopsis glabra Kobjakova, 1936, a species endemic to the Sea of Okhotsk, is supplementary reported. Most specimens were collected from steep slopes or hard bottoms at depths greater than 400 m by commercial shrimp trap or gill nets operated by local fishermen. Differentiation of the new species is primarily based on a morphological comparison, supplemented by a preliminary genetic analysis of partial segments of the mitochondrial 16S rRNA gene. An identification key to the species of Pandalopsis is presented.
