To date, three species of the family Ancorabolidae, three species of the family Argestidae, and one species of the family Rhizothrichidae are known from the deep sea of the Gulf of California. The descriptions of two new species, and collected from the Southern Trough of Guaymas Basin at 1440 m and 1642 m depths, respectively, are presented herein. The closest relatives of these two species, Por, 1964 and Soyer, 1964 are known from the Mediterranean, but some relatives have been reported also from the southern Atlantic. is undoubtedly related to Por, 1964 known from Israel and Banyuls-sur-Mer (France). These two species can be separated by the armature complement of the basis of the maxillule, by the armature complement of the syncoxa of the maxilliped, and by the relative position of the anal operculum. showed to be closely related to Soyer, 1964 known from Banyuls-sur-Mer only. The latter two species can be separated by the armature complement of the syncoxa of the maxilliped, by the structure of the antenna, and by the inner armature complement of the third exopodal segment of the fourth swimming leg.
迄今为止，在加利福尼亚湾深海已发现锚蝽科3个物种、阿盖斯特蝽科3个物种和根刺蝽科1个物种。本文描述了分别从瓜伊马斯盆地南槽1440米和1642米深处采集的两个新物种。这两个物种最亲近的亲属，即1964年的Por和1964年的Soyer，在地中海被发现，但在南大西洋也有一些亲属被报道。无疑与1964年来自以色列和法国滨海巴尼约尔的Por有关。这两个物种可以通过小颚基部的刚毛组成、颚足基节的刚毛组成以及肛盖的相对位置来区分。显示与仅来自滨海巴尼约尔的1964年的Soyer密切相关。后两个物种可以通过颚足基节的刚毛组成、触角的结构以及第四游泳足第三外肢节的内刚毛组成来区分。
