来自所有海洋的记录，其中大多数是在1990-2000年期间发表的，以及对9种被称为潜在软骨藻酸（DA）生产者的假菱形藻类群的个人未发表的观察，已被用来概述其地理分布。n.序列拟菱形藻f. seriata作为唯一的分类群仅在北大西洋发现。关于多纹拟步行虫的记录太少，而对北大西洋拟步行虫的鉴定也太不可靠，无法提供有关其分布的信息。Pseudo-nitzschia pungens和较少记录的P. fraurista，P. multiseries和P. australis似乎是世界性的。特别值得注意的是，分布最广的DA生产者，P. australis和P. multiseries。P. delicatissima和P. pseudodelicatissima的记录也表明了一个世界性的分布，尽管有一定的分类和鉴定模糊的资格。因此，问题是否大多数DA生产假菱形藻种是世界性的，可以回答一个试探性的“是”。
Records from all oceans, most of them published during 1990-2000, and personal unpublished observations of nine Pseudo-nitzschia taxa known as potential domoic acid (DA) producers have been used to outline their geographical distribution. Pseudo-nitzschia seriata f. seriata as the only taxon was found in the North Atlantic Ocean exclusively. The records of P. multistriata were too few and the identification of P. turgidula from the North Atlantic too unreliable to provide an idea about their distribution. Pseudo-nitzschia pungens and the less frequently recorded P. fraudulenta, P. multiseries and P. australis appeared to be cosmopolites. The wide distribution of the apparently most efficient DA producers, P. australis and P. multiseries, is especially noteworthy. The records of P. delicatissima and P. pseudodelicatissima also indicate a cosmopolitan distribution although with the qualification of certain taxonomic and identification ambiguities. Hence, the question of whether most DA-producing Pseudo-nitzschia species are cosmopolites may be answered with a tentative "yes".
