Abstract
A new species of the sand-burrowing dogielinotid amphipod genus Haustorioides Oldevig, 1958, Haustorioides furotai Ogawa, sp. nov., is described from Banzu tidal flat, east coast of Tokyo Bay, Japan. The new species is mainly characterized by a slender and triangular outer plate of the maxilliped, poorly setose antennae and pereopods, straightly acute posterodistal corner of epimeral plates 2 and 3, and an uncleft and ridged telson. Analyses of the mitochondrial cytochrome c oxidase subunit I sequences verified that H. furotai belongs to the monophyletic clade consisting of the other Haustorioides species. Additionally, Eohaustorioides Bousfield and Tzvetkova, 1982, and Parhaustorioides Ren, 2006 are synonymized with Haustorioides based on morphological analysis. An identification key to the species of the genus Haustorioides is also provided.Keywords
