Three strains of the toxic benthic dinoflagellate Prorocentrum hoffmannianum were isolated in the Canary Islands (north-east Atlantic Ocean, Spain). The identity of the strains was determined by phylogenetic analyses of partial LSU rDNA (D1-D2 regions) but their morphology based on SEM images corresponded to P. maculosum. Their toxin profiles were analyzed by liquid chromatography and high resolution mass spectrometry analysis (LC–HRMS) on cell extracts and culture media. Okadaic acid and three analogs were detected in all strains. Rather, in culture media the detected compounds were variable among strains, two of them being okadaic acid analogs not found on cell extracts. As a result, the taxonomy of the species was revised and P. maculosum is proposed as a junior synonym of P. hoffmannianum whose description is emended.

在加那利群岛（东北大西洋，西班牙）中分离出三株有毒的底鞭毛鞭毛衣原体霍夫曼氏菌。通过对部分LSU rDNA（D1-D2区）的系统发育分析确定了菌株的身份，但基于SEM图像的形态与黄斑假单胞菌相对应。通过液相色谱和高分辨质谱分析（LC-HRMS）对细胞提取物和培养基进行分析，分析了它们的毒素谱。在所有菌株中均检测到冈田酸和三个类似物。相反，在培养基中检测到的化合物在菌株之间是可变的，其中两个是在细胞提取物中未发现的冈田酸类似物。结果，该物种的分类被修改，斑节对虾被提议作为P. hoffmannianum的初级同义词，对其描述进行了修改。
