Thirteen species belonging to five genera of pelagic amphipods of the family Lestrigonidae were collected during a deep-water survey off western Mexico: four species of Hyperietta, two species of Hyperioides, five species of Lestrigonus, and one species each of Phronimopsis and Themistella. This represents 93% of all known species of Lestrigonidae world-wide. A total of 1092 specimens were obtained in 40 sampling localities in the Gulf of California (35) and off southwestern Mexico (5). Although sampling methodology was rather heterogeneous, two species, Hyperioides sibaginis and Lestrigonus bengalensis, were particularly abundant (336 and 562 specimens) and frequent (present in 24 and 31 localities) in the samples, representing 82% of the total catch. The southernmost distribution limit of Hyperietta stebbingi is extended to off SW Mexico. Of the 13 species that were collected during this survey, 10 and 8 species co-occurred at two sampling localities in the SE Gulf of California.
在墨西哥西部的一次深水调查中，采集到了属于莱氏水蚤科五个属的13种远洋性桡足类动物：4种超雌水蚤属、2种似超雌水蚤属、5种莱氏水蚤属，以及1种拟叶水蚤属和1种忒弥斯水蚤属。这占全球已知莱氏水蚤科物种的93%。在加利福尼亚湾（35个）和墨西哥西南部海域（5个）的40个采样点共采集到1092个标本。尽管采样方法相当多样，但样本中两种物种，即西氏似超雌水蚤和孟加拉莱氏水蚤特别丰富（分别为336和562个标本）且分布频繁（分别出现在24和31个采样点），占总捕获量的82%。斯氏超雌水蚤的最南分布界限延伸至墨西哥西南部海域。在本次调查采集到的13种物种中，有10种和8种共同出现在加利福尼亚湾东南部的两个采样点。
