| 摘 要： | 浮游介形类是海洋生态系统中极为丰富的一类小型甲壳动物,是海洋浮游动物的重要组成部分。吸海萤科是介形纲吸海萤目下的一大类群,其中,浮萤族已记述21属的生物。本文报道和描述了新近采自南海中部的一个浮萤族新属新种--复合多腺浮萤。该新物种与相关属和种可通过综合相关特征进行区分：位于右不对称腺体上方的侧角腺开口于近后缘;沿其壳腹缘具有一列排列密集的边缘腺;其前器官形状的综合特点与族内其他属物种均不同;第一触角的e刚毛不具有毛或刺;第二触角内肢乳状突表现为一具有腹面中央凹的椭圆隆起,第一外肢具有一根小背前缘刺,第一与第二外肢愈合,第三与第四外肢不具有刚毛或刺;大颚的第一内肢具一根长腹侧刚毛,第二内肢具一根腹侧刚毛;小颚第一内肢具两根基部刚毛;第五肢的第一外肢仅具一根腹侧刚毛;第六肢的第一与第二外肢不具有腹侧刚毛。其壳上主要腺体及开口位置与其他已记录属种的显著区别是该新属的主要特征。

| Abstract: | Planktonic ostracods are small crustaceans abundant in marine ecosystem worldwide as appreciable part of marine zooplankton. Family Halocyprididae is a large group of halocyprid ostracods, and the tribe Conchoeciini has contained 21 genera previously. We described a further genus with a species Polyconchoecia commixtus gen. et sp. nov. from the middle of South China Sea in this study. The new species can be distinguished from related genera and species in having a unique combination of these characteristics: a lateral gland placed over right asymmetric gland and open near posterior margin; dense edge glands placed along ventral margin of carapace in line; shape of frontal organ; e-seta of first antenna is bare; endopod of second antenna has one small oval hump with central concave on mid-ventral margin, instead of processus mamillaris, exopod 1 has a small disto-dorsal spine, exopod 1 and 2 are fused, exopod 3 and 4 are bare; endopod 1 of mandible has one long ventral seta, endopod 2 has one ventral seta; maxillary endopod 1 has two basal setae; endopod 1 of fifth limb has only one ventral seta; endopod 1 of sixth limb and endopod 2 have no ventral seta. The definite distinctions in locations of major glands are the key characteristics of the new genus. |
