在对中国科学院南海海洋生物标本馆馆藏芋螺科 Conidae 标本, 以及近年来在南海补充采集的标本进行整理的过程中, 通过形态分类学方法鉴定发现隶属于芋螺属 Conus 的中国海新记录种1种: 锈色芋螺 Conus ferrugineus Hwass in Bruguière, 1792, 标本采自西沙群岛。文章描述了该种的外部形态, 查明了其生活习性和地理分布特点, 并与相似种犊纹芋螺 Conus vitulinus Hwass in Bruguière, 1792 进行了比较, 通过壳口内面前沟部位的颜色可将两者区分开: 锈色芋螺呈白色, 而犊纹芋螺呈紫 (褐) 色; 同时对这两个相似种的其他区别特征进行了总结。

A conid species, Conus ferrugineus Hwass in Bruguière, 1792, was recorded from China for the first time based on specimens deposited in the Marine Biodiversity Collections of the South China Sea, Chinese Academy of Sciences, and on samples recently collected from voyages to the South China Sea. The specimens were collected from the Xisha Islands. The shell morphological features of this species were presented, as well as its habitat and distribution. C. ferrugineus is easily confused with its sympatric sibling species C. vitulinus Hwass in Bruguière, 1792. The most remarkable difference is its uniformly white aperture, in contrast to the violet to violet brown base of the aperture in C. vitulinus. The identification characteristics between them were also discussed and summarized in this paper.
