一种新的海洋硅藻化石--休眠孢子形态的瓦洛迪克斯Suto gen.11月，使用挪威海深海钻探项目现场338、西北太平洋436和438以及加利福尼亚州陆地纽波特海滩段的样本进行了描述。瓦洛迪克斯的特点是沿瓣膜外缘有单环静脉，下瓣膜覆盖有大小不同的圆形凹陷，隆起平缓。形态属内含3个新种和1个新组合：单纯瓦洛迪克斯Suto sp.、复杂瓦洛迪克斯(Vallodisus Complus Suto sp.)、轮纹瓦氏盘藻Vallodisus lanceolatus Suto sp.11月和瓦洛迪氏菌(Vallodisus chinchae(Mereschkowsky)Suto comb.)11月
A new fossil marine diatom resting spore morphogenus, Vallodiscus Suto gen. nov., is described using samples from Deep Sea Drilling Project Site 338 in the Norwegian Sea, Sites 436 and 438 in the north‐west Pacific Ocean and the onland Newport Beach Section, California. Vallodiscus is characterized by a single ring of veins along the epivalve margin and a hypovalve covered with circular depressions of several sizes with gentle elevation. The morpho‐genus bears three new species and one new combination: Vallodiscus simplexus Suto sp. nov., Vallodiscus complexus Suto sp. nov., Vallodiscus lanceolatus Suto sp. nov. and Vallodiscus chinchae (Mereschkowsky) Suto comb. nov.
