Two new deep-water species of the snapping shrimp genus Alpheus Fabricius, 1798 are described based on the material collected by the expeditions BIOPAPUA, BOA1 and MIRIKY, organised by the Muséum National d'Histoire Naturelle in Paris. Alpheus alaincrosnieri n. sp. from the A. brevirostris (Olivier, 1811) group is described based on material dredged at depths of 198-408 m near the coasts of Papua New Guinea, Vanuatu and Madagascar. This species also occurs in the Philippines, based on morphological characters of a mutilated specimen from Masbate reported by Chace (1988). Alpheus alaincrosnieri n. sp. is unique within the A. brevirostris group, in having small orbital teeth. In most other features, A. alaincrosnieri n. sp. is morphologically closest to A. kagoshimanus Hayashi Nagata, 2000, A. longipalma Komai Ohtomi, 2018, A. macroskeles Alcock Anderson, 1894, A. nonalter Kensley, 1969 and A. acutocarinatus De Man, 1909. Alpheus vanuatu n. sp. is described based on several specimens dredged at depths of 231-331 m off Espirito Santo, Vanuatu. This species most likely represents a deep-water member of the newly defined A. paracrinitus species group, sharing most morphological characters with A. tenuipes De Man, 1910 and A. labis Banner Banner, 1982.
基于巴黎国家自然历史博物馆组织的BIOPAPUA、BOA1和MIRIKY考察队收集的材料,描述了鼓虾属阿尔费乌斯(Alpheus Fabricius,1798)的两个新深水物种。阿尔费乌斯·阿兰·克罗斯涅里新种(Alpheus alaincrosnieri n. sp.)属于短吻阿尔费乌斯(A. brevirostris (Olivier, 1811))类群,根据在巴布亚新几内亚、瓦努阿图和马达加斯加海岸附近198 - 408米深处挖掘的材料进行描述。根据查斯(Chace,1988)报道的来自马斯巴特的一个残缺标本的形态特征,该物种在菲律宾也有分布。阿尔费乌斯·阿兰·克罗斯涅里新种在短吻阿尔费乌斯类群中独一无二,具有小的眼眶齿。在大多数其他特征上,阿尔费乌斯·阿兰·克罗斯涅里新种在形态上最接近2000年的贺阳阿尔费乌斯(A. kagoshimanus Hayashi Nagata)、2018年的长掌阿尔费乌斯(A. longipalma Komai Ohtomi)、1894年的大肢阿尔费乌斯(A. macroskeles Alcock Anderson)、1969年的无变化阿尔费乌斯(A. nonalter Kensley)和1909年的尖棱阿尔费乌斯(A. acutocarinatus De Man)。阿尔费乌斯·瓦努阿图新种(Alpheus vanuatu n. sp.)根据在瓦努阿图圣埃斯皮里图岛近海231 - 331米深处挖掘的几个标本进行描述。该物种很可能代表新定义的副海百合阿尔费乌斯(A. paracrinitus)物种组的一个深水成员,与1910年的细足阿尔费乌斯(A. tenuipes De Man)和1982年的拉比斯阿尔费乌斯(A. labis Banner Banner)具有大多数形态特征。
