Alpheopsis balaeniceps sp. nov. is described based on a single male specimen from Moorea, French Polynesia. The new species is unique within the genus Alpheopsis Coutière, 1896 in possessing balaeniceps-type setae on the fingers of both chelipeds, being especially well developed on the major chela. Within the family Alpheidae, this feature exists only in some species of the distantly related genus Alpheus Fabricius, 1798, however, only on the minor cheliped. This convergence between Alpheopsis and Alpheus is another example of the remarkable diversity and plasticity of the alpheid chelipeds.
基于来自法属波利尼西亚莫雷阿岛的一个雄性标本，描述了新物种巴氏阿氏虾（Alpheopsis balaeniceps sp. nov.）。在1896年的阿氏虾属（Alpheopsis Coutière）中，这个新物种很独特，其螯足的指节上都有露脊鲸型刚毛，在大螯上尤其发达。在鼓虾科（Alpheidae）中，这一特征仅存在于远亲鼓虾属（Alpheus Fabricius，1798）的一些物种中，不过仅存在于小螯上。阿氏虾属和鼓虾属之间的这种趋同现象是鼓虾科螯足显著多样性和可塑性的又一个例子。
