在墨西哥湾东北部两年多的时间里，人们观察到了罕见的硅藻Nanoneis Longta的种群。这使得可以在扫描和透射电子显微镜中详细检查阀门的精细结构。种群与物种原始描述的基本特征相匹配，但显示出更大的大小范围。我们使用扫描电子显微镜发现，沿着瓣膜周长存在一种新的结构，即边缘门脉。该物种在温跃层以下、25~125 m深度和夏季至初秋期间最为丰富。包括了物种的修订定义，以适应观察到的大小范围和新的特征。
A population of the rarely reported diatom Nanoneis longta was observed over a period of more than two years in the northeastern Gulf of Mexico. This permitted a detailed examination of the fine structure of the valve in scanning and transmission electron microscopy. The population matched the basic features of the original description of the species, but displayed a greater size range. Our use of SEM revealed the presence of a novel structure, the porticus marginalis, along the perimeter of the valve. The species was most abundant below the thermocline, at depths between 25 and 125 m, and from summer to early fall. An emended definition of the species to accommodate the observed size range and the new feature is included.
