从葡萄牙蛤蚌的鳃丝中描述了一种新的顶复合体种——大西洋鲈，它在那里造成了很高的死亡率。游动孢子在大小和形状、尺寸、2根鞭毛的插入以及寄主的身份上与其他种类的Perkinsus不同。另一方面，其生活史阶段在超微结构上与仅有的一种Perkinsus marinus有一定差异。当蛤被大量寄生时，在足部和套部组织中发现了超微结构上相似的生命周期阶段。
A new apicomplexan species, Perkinsus atlanticus is described from gill filaments of the clam Ruditapes decussatus (Bivalvia) from Portugal, where it causes great mortality. The zoospores differ from those of other species of Perkinsus in size and shape, dimensions, insertion of the 2 flagella, and in the identity of the host. On the other hand, the life cycle stages showed some ultrastructural differences compared with Perkinsus marinus, the only species previously studied in detail. When the clams were parasitized heavily, ultrastructurally similar life cycle stages were found in foot and mantle tissues.
