A new species of the snapping shrimp genus Alpheus Fabricius, 1798 is described based on material from Galicia Bank, an offshore seamount off northwestern Spain. The type series of Alpheus gallicus n. sp. was collected at a depth of 768-785 m, making it one of the deepest occurring snapping shrimps. The new species belongs to the Alpheus macrocheles species group and is morphologically most similar to several deep-water members of this group, viz. A. lentiginosus Anker Nizinski, 2011, A. platydactylus Coutière, 1897, A. romensky Burukovsky, 1990, as well as to the shallow-water A. macrocheles (Hailstone, 1835). The new species can be distinguished from all of them by some features on the minor cheliped and dactyli of the third to fifth pereiopods. In addition to morphology, DNA barcoding of the COI gene distinguished A. gallicus n. sp. from all related species with available barcode sequences.
基于采自西班牙西北部近海海山加利西亚海隆的材料，描述了鼓虾属（Alpheus Fabricius，1798）的一个新物种。高卢鼓虾（Alpheus gallicus n. sp.）的模式系列样本采自768 - 785米深处，使其成为已知分布最深的鼓虾之一。新物种属于大螯鼓虾物种组，在形态上与该组的几个深水成员最为相似，即2011年的雀斑鼓虾（A. lentiginosus Anker Nizinski）、1897年的扁指鼓虾（A. platydactylus Coutière）、1990年的罗缅斯基鼓虾（A. romensky Burukovsky），以及浅水的大螯鼓虾（A. macrocheles (Hailstone, 1835)）。新物种可通过小螯足以及第三至第五步足指节上的一些特征与上述所有物种区分开来。除形态学特征外，基于细胞色素氧化酶亚基I（COI）基因的DNA条形码分析也将高卢鼓虾与所有具有可用条形码序列的相关物种区分开来。
