【摘要】 蒙古裸腹溞是旧大陆唯一得到承认的盐水裸腹溞,是中国枝角类的新纪录,本文描述了其形态、生态和分布。 这种裸腹溞和同属其它种类的主要区别在于雌性第一胸肢倒数第二节上不具前刺,而一般对裸腹溞属种的鉴定时并不解剖观察第一胸肢。这点可能就是本种分布的报道迄今仅局限于晋南和银川地区的缘故。更多还原

【Abstract】 Moina mongolica appears to be the only halophilic species of Moina in the old world, being a new record of dadocera in China. Their morphology, ecology and distribution are described in this paper.This species differs from other members of the genus by the absence of anterior seta on penultimate segment of first legs in female. However this character has not been considered in common identification of this genus, as a result its distribution has still been restricted to Jinan and Yinchan regions in China.更多还原
