The present study deals two new alpheid shrimp species from the transisthmian Salmoneus ortmanni (Rankin, 1898) complex. Salmoneus alvarezi sp. nov. is described based on materials collected in Bahía Málaga, Colombia, and Punta Morales, Costa Rica, and is closely related to the western Atlantic S. ortmanni and S. wehrtmanni Anker, 2011. Salmoneus malagensis sp. nov. is described based on specimens from Bahía Málaga, Colombia, and beyond any doubts represents the eastern Pacific sister species of the western Atlantic S. carvachoi Anker, 2007. The two new species can be easily distinguished from each other by a number of morphological characters and colouration, and in addition appear to be ecologically separated. All previous records of S. ortmanni from the eastern Pacific are reassigned, some tentatively, to S. alvarezi sp. nov. based on description, illustrations or ecological data.
本研究涉及来自地峡间的萨尔蒙内斯·奥特曼尼（Rankin，1898）复合体的两种新的藻虾科虾类物种。新物种阿尔瓦雷兹萨尔蒙内斯虾（Salmoneus alvarezi sp. nov.）是根据在哥伦比亚的巴伊亚·马拉加和哥斯达黎加的莫拉莱斯角采集的材料描述的，它与西大西洋的奥特曼尼萨尔蒙内斯虾（S. ortmanni）和韦尔特曼尼萨尔蒙内斯虾（S. wehrtmanni Anker，2011）密切相关。新物种马拉加萨尔蒙内斯虾（Salmoneus malagensis sp. nov.）是根据来自哥伦比亚巴伊亚·马拉加的标本描述的，无疑是西大西洋的卡瓦乔伊萨尔蒙内斯虾（S. carvachoi Anker，2007）在东太平洋的姊妹物种。这两个新物种可以通过一些形态特征和体色很容易地相互区分，此外它们在生态上似乎也相互隔离。根据描述、插图或生态数据，东太平洋以前所有的奥特曼尼萨尔蒙内斯虾记录都被重新归类，有些是暂定的，归为阿尔瓦雷兹萨尔蒙内斯虾新物种。
