摘要:

文章描述了发现于南海南沙海槽的一新种——南沙深海浮萤(Bathyconchoecia nanshaensis sp. nov.)。该种个体小,壳长度(CL<1.0mm)和壳高度(~70% CL)与小深海浮萤(Bathyconchoecia paulula)和太平洋深海浮萤(Bathyconchoecia pacifica)非常相似。但是, 根据不对称腺体开口的位置、下颌骨的臀齿边缘的结构, 以及第六肢的位置可以把该种和这两个相似的物种区分开。

Abstract:

A new species of halocyprid ostracod, Bathyconchoecia nanshaensis sp. nov., from the Nansha Trough (the North-West Borneo Trough), southern South China Sea is illustrated and described in detail. The species is a small one that closely resembles Bathyconchoecia paulula Deevey, 1968 and Bathyconchoecia pacifica Chavtur, 1977 in terms of its carapace length (CL; <1.0 mm) and relative height (~70% CL). However, it can be easily distinguished from these species by the locations of its asymmetrical glands’ opening, by the structure of the coxal toothed edge of the mandible, and by the setation of the sixth limb.

Key words: Bathyconchoeciinae, systematics, zooplankton, Nansha Trough, Pacific Ocean
