Title: Identities of three taxa of the hippolytid shrimp genus Heptacarpus (Crustacea: Decapoda: Caridea), with description of a new species from East Asian waters
Abstract: Taxonomy of the two previously described species of the hippolytid shrimp genus Heptacarpus Holmes, 1900, H. camtschaticus (Stimpson, 1860) and H. geniculatus (Stimpson, 1860), are reassessed. It has been found that Eualus geniculata longirostris Kobjakova, 1936, which has been regarded as a junior synonym of Heptacarpus geniculatus, is a valid taxon, herein reinstated as a full species. It has been found that two species were confounded in previous literature under the name H. camtschaticus, and one of them is described as new, H. acuticarinatus n. sp. Three species, H. camtschaticus, H. geniculatus and H. longirostris, are redescribed. These four species all belong to an informal species group characterized by the lack of pereopodal epipods. Differences in morphology and distributional pattern among the four species are discussed. A key in aid of the identification of the Asian species belonging to the species group is provided.
