摘　　要：微型硅藻是海洋浮游植物的重要组成类群,由于其个体微小,在以往的研究中大多被忽略了。本文利用透射电镜(TEM)对若干采自我国沿海海域的样品进行观察,经鉴定,确认一个我国微型硅藻类的新记录属——微壳藻属Nanofrustulum Round,Hallsteinsen & Paasche1999。对该属及该属一个新记录种的主要形态学特征进行了描述,提供了透射电镜下的照片,并对相似属种进行了形态学比较研究。Marine nanoplanktonic diatoms have been frequently either underestimated or overlooked in phytoplankton investigations due to their small size （2-20 um） which will mostly pass through a regular phytoplankton net of 76 um pore size. For nanoplanktonic diatom classification, water samples （each 2000 mL） were collected from several representative sea areas of China coast. Nanofrustulum Round, Hallsteinsen ＆ Paasche was identified as a newly recorded diatom genus for China under transmission electron microscope （TEM）. Its sole species was found, i.e., N. shiloi （Lee, Reimer ＆ McEnery） Round, Hallsteinsen ＆ Paasche. Detailed description of the taxonomic characteristics with TEM photographs of this species and its ecological behavior and distribution are given in this paper. Morphological characteristics comparisons among several resembling genera were discussed.
