记述了厦门湾的伪镖水蚤科(Pseudodiaptomidae G O Sars, 1902)1个新种——郑氏伪镖水蚤(Pseudodiaptomus zhengi Guo & Wang, sp. nov.).形态上,新种雌性腹部各节光滑无小刺、生殖节的侧前端和生殖厣的前端各具1排长刺,与海洋伪镖水蚤(P. marinus Sato, 1913)存在明显的形态差异; 两者基于线粒体细胞色素氧化酶Ⅰ(mtCOⅠ)基因序列的种间遗传差异为22.4%～23.7%.模式标本(2016年4月至2017年7月采集于厦门湾)保存于厦门大学海洋科技博物馆.

A new species of Pseudodiaptomidae,Pseudodiaptomus zhengi Guo & Wang,sp.nov.,which was misidentified as P.marinus Sato,1913 by Zheng et al.(1965),is described.The differences between this new species and P.marinus are as follows: all female urosome segments without rows of coarse teeth on their distal margins,a row of spinules located on the anterolateral margin of female genital segment,and a row of spinules located in front of female genital operculum.The mitochondrial gene cytochrome oxidase subunit Ⅰ(mtCOⅠ)gene sequences support the conclusion based on morphological data,with distinct divergence values 22.4% to 23.7% between P.zhengi and P.marinus.All types of specimens,which were collected from Xiamen Bay during April 2016 to July 2017,are archived in the Museum of Marine Science and Technology,Xiamen University.
