M. Hoppenrath和M.赛琳娜2006.伪囊甲藻属（Pseudothecadinium campbellii gen. nov. et sp. nov.），一种产于俄罗斯鄂霍次克海的光养、囊状、海洋浮游种。Phycologia 45：260-269. DOI：10.2216/05-23.1通过对来自俄罗斯鄂霍次克海的标本进行光学和扫描电子显微镜观察，描述了一种新的海洋浮游甲藻。新属和新种为伪囊甲藻PseudothecadiniumcampbelliiHoppenrath & Selinagen. nov.，长36.9-52.5 μm，深31.8-45.0 μm，细胞侧面观卵圆形，侧面扁平，具下降的扣带，扣带宽约4 - 6个，具囊，板式Po 4′ 2a 4″ 4c 5（？）s 5′″ 1″″，含有叶绿体。背板光滑，孔分散，有一个独特的第二个前闰板与“腹孔”，前扣带板系列是不完整的，在腹侧视图中看到的antapical细胞轮廓是倾斜的。板块的模式和板块排列不同于所有描述的甲藻属，但最相似的Thecadinium和Thecadiniopsis。
M. Hoppenrath and M. Selina. 2006. Pseudothecadinium campbellii gen. nov. et sp. nov. (Dinophyceae), a phototrophic, thecate, marine planktonic species found in the Sea of Okhotsk, Russia. Phycologia 45: 260–269. DOI: 10.2216/05-23.1 A new marine planktonic dinoflagellate is described from light and scanning electron microscopical observations of specimens from the Sea of Okhotsk, Russia. Pseudothecadinium campbellii Hoppenrath & Selina gen. and sp. nov. is 36.9–52.5 μm long, 31.8–45.0 μm deep, ovoid in lateral cell view, laterally flattened, with a descending cingulum, displaced about four to six cingular widths, thecate, with the plate formula Po 4′ 2a 4″ 4c 5(?)s 5′″ 1″″ and it contains chloroplasts. Thecal plates are smooth with scattered pores, there is a distinctive second anterior intercalary plate with a ‘ventral pore’, the precingular plate series is incomplete and the antapical cell contour is oblique when seen in ventral view. The plate pattern and the plate arrangement differ from all described dinoflagellate genera, but is most similar to Thecadinium and Thecadiniopsis.
