The Asian cyclopoid copepod Mesocyclops pehpeiensis Hu, 1943 has been reported as an introduced species at several locations in the western hemisphere. In the United States, reports of this exotic species are restricted to localities in Louisiana, Mississippi, and Washington D.C. This report documents a new record of occurrence for M. pehpeiensis from the western basin of Lake Erie. The detection of M. pehpeiensis in Lake Erie constitutes the first record of this species from the Laurentian Great Lakes, and the northernmost record in the western hemisphere. The species was found in 2016, 2017 and 2018, including females with egg sacks, and can therefore be considered established in the area. The occurrence of M. pehpeiensis in Lake Erie suggests that this Asian copepod may be more widely distributed in North America than is currently understood.
亚洲剑水蚤类桡足动物佩氏中剑水蚤（Mesocyclops pehpeiensis Hu，1943）已被报道为西半球多个地点的外来入侵物种。在美国，该外来物种的报告仅限于路易斯安那州、密西西比州和华盛顿特区的局部地区。本报告记录了佩氏中剑水蚤在伊利湖西部流域出现的新记录。在伊利湖检测到佩氏中剑水蚤是该物种在劳伦琴五大湖的首次记录，也是西半球最北的记录。该物种于2016年、2017年和2018年被发现，包括带有卵囊的雌性个体，因此可以认为已在该地区定殖。佩氏中剑水蚤在伊利湖的出现表明，这种亚洲桡足动物在北美的分布可能比目前所知的更为广泛。
