鞭毛虫是根据它们的形态特征来分类的。在分类学中，原始出版物中对一个物种的诊断所描述的特征被认为是该物种最基本的定义。对于从最初分配的属转移到另一个属的种，其基名必须在修订提案中清楚地引用。然而，在命名法规建立和采用之前所作的描述中，基本名词的引用有时不明确，其不确定性造成了分类混乱。在此背景下，作为鞭毛纲分类学早期描述的物种之一的proorocentrum lima (Ehrenberg) Stein一直是后来研究的困惑之源，因为原始描述和绘图的形态特征与目前所了解的P. lima略有不同。爱伦伯格（Ehrenberg, 1860）以利马隐胞菌（Cryptomonas lima）的名称描述了利马隐胞菌，但没有编号。其描述为：卵黄斑点卵黄睾丸、单纯鞭毛、卵黄形态、圆形赘肉、短感减弱性睾丸、瘦肉赘肉。Intestina flavofusca。Ehrenberg描述，细胞呈卵形，在前缘圆扩张，顶端逐渐变细，微缺。细胞有一根鞭毛。罕见的点状分布在瓣膜上。他在意大利索伦托收集了这种生物。在接下来的一篇论文中，Ehrenberg（1873）附上了一些他在1859年绘制的C. lima的图画。Stein（1878）将C. lima转移到proorocentrum属，因为C. lima的细胞形状与proorocentrum属相似。但斯坦的论文被忽视了，只被少数研究人员引用。独立于Stein的修正，Cienkowski描述了一种与P. lima形态相似的物种，并将其命名为Exuviaeila marina
Dinoflagellates are classified based on their morphological features. In taxonomy, characteristics described in the diagno sis of a species in the original publication are thought to be the most fundamental definition of the species. For species that were transferred to another genus from the one allocated origi nally, its basionym must be clearly cited in the proposal of the revision. However, in descriptions made before the establish ment and adoption of the nomenclature codes, the citation of a basionym was sometimes unclear, and its uncertainty caused taxonomic confusion. In this context, Prorocentrum lima (Ehrenberg) Stein, one of the species described in the early stages of dinoflagellate taxonomy, has been a source of confu sion for later studies, since the morphological characteristics of the original description and the drawing is a little different to P. lima as currently understood. P. lima was described by Ehrenberg (1860) under the name of Cryptomonas lima, without a figure. The description of C. lima was as follows: Testula fragili silicea ovata punctis asperis raris obsita, flagello simplici, forma ovata, postica parte turgente rotundata, antica breviter sensim attenuata, leviter emarginata. Intestina flavofusca. Ehrenberg described that, the cell is ovate, roundly dilated in the anterior margin, tapering apically and slightly emarginate. The cell has a single flagellum. Rare punctations are scattered over the valve. He had collected the organism in Sorrento, Italy. In a following paper, Ehrenberg (1873) attached some drawings of C. lima drawn by himself in 1859. Stein (1878) transferred C. lima to the genus Prorocentrum because the cell shape of C. lima was similar to the genus Prorocentrum. But Stein's paper has been overlooked and only referred by a small number of researchers. Independently from the revision by Stein, a morphologically similar species resembing P. lima was described and named Exuviaeila marina by Cienkowski
