A new species of the alpheid shrimp genus Athanas Leach, 1814 is described based on a holotype from Wakasa Bay, Sea of Japan side of Honshu, Japan, at a depth of 90 m. Athanas exilis n. sp. appears close to A. sydnyensis Anker & Ahyong, 2007, but is distinguished from the latter by some morphological features, including the different shape of the telson, the shorter antennular stylocerite, more strongly produced distal lamella of the antennal scaphocerite, and less developed armature of the merus of the major cheliped. Preliminary genetic analysis using the mitochondrial 16S rRNA gene was performed to compare interspecific genetic divergence within the genus.
描述了一种新的糠虾属（Athanas Leach, 1814）虾类，基于来自日本本州日本海侧若狭湾水深 90 米处的一个正模标本。Athanas exilis n. sp. 与 A. sydnyensis Anker & Ahyong, 2007 密切相关，但通过一些形态特征可以与后者区分开来，包括尾节的不同形状、触角小梗的较短、触角扇骨的远端鳞片更强烈地产生、以及较大螯足的长节的装备程度较低。使用线粒体 16S rRNA 基因进行了初步的遗传分析，以比较属内种间的遗传分歧。
