A new species of the genus Sarsarietellus from Korean waters, S. orientalis n. sp. is described based on both sexes. This is very closely related to S. suluensis Ohtsuka, Nishida and Machida, 2005 , but is readily distinguished by the following characteristics: in the female (1) narrow head; (2) nearly symmetrical posterior corners of last pedigerous somite, not extending beyond the genital double-somite; (3) antennary endopod slightly longer than the exopod; (4) nearly equal length of three outer spines and the terminal spine of the exopod of the fifth leg, except for the proximal third outer spine; and in the male the left fifth leg with two whip-like setae on the tip of the second exopodal segment not being rotated outside. Sarsarietellus orientalis is the fourth species of the genus Sarsarietellus, while the male of Sarsarietellus species is the first reported. The habitat colonization of arietellids is reconsidered.
描述了来自韩国海域的Sarsarietellus属的一个新物种——东方Sarsarietellus（S. orientalis n. sp.），涵盖了该物种的两性特征。它与2005年由大冢、西田和町田描述的苏禄Sarsarietellus（S. suluensis）密切相关，但可通过以下特征轻松区分：雌性个体具有（1）头部狭窄；（2）最后一个带足节的后角几乎对称，不延伸至生殖双节；（3）触角内肢略长于外肢；（4）第五对足外肢的三根外侧刺和末端刺长度近乎相等，但近端第三根外侧刺除外；雄性个体的左第五对足，其第二外肢节末端的两根鞭状刚毛不向外旋转。东方Sarsarietellus是Sarsarietellus属的第四个物种，而Sarsarietellus属物种的雄性个体是首次报道。对阿里特虫类的栖息地定殖情况进行了重新审视。
