During a survey of the mangrove infauna on the Iranian side of the Persian Gulf and the Gulf of Oman several specimens of a new alpheid shrimp, Salmoneus shojaei sp. nov., were collected around pneumatophores of mangrove trees, mostly in association with the larger burrowing snapping shrimps of the genus Alpheus Fabricius, 1798. The new species appears to be a member of the S. gracilipes species group and is morphologically closest to S. colinorum De Grave, 2004 and S. alpheophilus Anker Marin, 2006. However, a unique combination of morphological characters, such as the carapace without rostral carina, the unarmed ischium of the major cheliped, the armed ischia of the minor cheliped and second pereiopod, the very slender dactyli of the fourth and third pereiopods, and the posterior margin of the telson with a deep U-shaped notch, distinguishes the new species from all other members of the S. gracilipes group. In addition, S. shojaei sp. nov. presents a diagnostic, albeit very faint, banding of the pleon, which separates it from most other species of the S. gracilipes group with known colour patterns. A DNA barcode (a partial fragment of the mitochondrial gene, CO1), as well as partial fragments of the mitochondrial 16S rRNA and the nuclear H3 genes, are provided to genetically characterise the new taxon.
在对伊朗波斯湾和阿曼湾的红树林无脊椎动物进行调查时，在红树林气生根周围收集到了几种新的阿拉夫虾，即 Salmoneus shojaei sp. nov.，这些虾主要与更大的挖掘性螯虾属 Alpheus Fabricius, 1798 有关。这个新物种似乎是 S. gracilipes 物种群的一员，在形态上与 S. colinorum De Grave, 2004 和 S. alpheophilus Anker Marin, 2006 最为接近。然而，独特的形态特征组合，如无额脊的头胸甲、大螯足无武装的坐骨、小螯足和第二对步足的武装坐骨、第四和第三对步足非常细长的指节、以及尾节后缘的深 U 形缺口，将这个新物种与 S. gracilipes 组的所有其他成员区分开来。此外，S. shojaei sp. nov. 呈现出一个可诊断的、尽管非常微弱的、带有斑纹的腹部，这使它与大多数具有已知颜色模式的 S. gracilipes 组的其他物种区分开来。提供了 DNA 条码（线粒体基因 CO1 的一个片段）以及线粒体 16S rRNA 和核 H3 基因的部分片段，以对新分类群进行遗传特征描述。
