| Abstract: |
| The male of Candacia varicans Giesbrecht, 1892 from the South China Sea was recorded and described. In general, the male of C. varicans is morphologically similar to those of C. armata and C. curta. However, it is distinguished with them by below several morphological characters: (1) posterolateral corners of the fifth thoracic segment prominently sharp and symmetrical; (2) right side of posterior edge of genital segment with a small backward protuberance; and (3) the dorsal surface of the third segment of the fifth pereiopod with a squama-shaped protuberance. |
| 中文摘要: |
| 本文基于南海采集的浮游动物标本，详细描述了腹突平头水蚤Candacia varicans Giesbrecht，1892的雌雄个体形态分类特征。本文报道腹突平头水蚤雄性个体是中国海的首次记录。腹突平头水蚤雄性在形态上与武平头水蚤和短平头雄性个体相似，但腹突平头水蚤可以通过以下几个特征与上述两个物种区分：1）头胸部：末胸节后侧角尖锐，左右对称；2）生殖节：右侧下缘具一个指向后方的小突起；3）第五胸足：右足第3节近末端背面具1片状突起。 |
