本文记述了采自福建省厦门市的中国对虾一新种-长吻虾Alpheus Fabricius，1798，A. longipalma，描述和说明的基础上的材料从鹿儿岛湾，九州，日本。它被称为A。brevirostris（Olivier，1811）种组，与A. macrophiles Alcock安德森，1894年，在孟加拉湾和安达曼海有确定的分布;塔利斯马尼·库蒂埃，1898年，来自大西洋东部。雄性小螯肢极长，近等长或长于大螯肢，按比例较短的趾将新种与A.巨噬细胞该新种的触角柄较不伸长，触角舟状体的远侧片层较发达，呈圆形。塔利斯马尼。所有新物种的标本都是从超过200米的深度拖网捕捞的。
A new species of the snapping shrimp genus Alpheus Fabricius, 1798, A. longipalma, is described and illustrated on the basis of material from Kagoshima Bay, Kyushu, Japan. It is referred to the A. brevirostris (Olivier, 1811) species group, and appears closest to A. macroskeles Alcock Anderson, 1894, known with certainty from the Bay of Bengal and Andaman Sea, and A. talismani Coutière, 1898 from the eastern Atlantic. The greatly elongate minor cheliped in males, being subequal to or longer than the major cheliped with proportionally shorter dactylus distinguish the new species from A. macroskeles. The less elongate antennular peduncle and better-developed, rounded distal lamella of the antennal scaphocerite differentiate the new species from A. talismani. All specimens of the new species were trawled from depths greater than 200 m.
