Navicula nielsfogedii was recently described from tropical and sub-tropical Africa. New data on its distribution from several countries in Asia are provided in this paper, together with morphological observations and environmental information about the habitats where it was found. Since N. nielsfogedii was previously misidentified as Navicula heimansioides the morphology of both taxa is compared.

关于 Navicula nielsfogedii JC Taylor & Cocquyt 的地理分布

最近从热带和亚热带非洲描述了 Navicula nielsfogedii。本文提供了来自亚洲几个国家的有关其分布的新数据，以及有关其发现栖息地的形态观察和环境信息。由于 N. nielsfogedii 之前被误认为是 Navicula heimansioides，因此比较了两种分类群的形态。
