摘要甲藻2新种：卵形异囊藻Iwataki&Fukuyo sp.11月和岩崎异冠藻Heterocapsa orientalisIwataki，Botes&Fukuyo sp.，并用光镜、荧光显微镜、扫描电子显微镜和透射电子显微镜对其体尺和细胞形态进行了描述。这些种具有典型的异囊藻属的膜板排列：Po，cp，5‘，3a，7“，6c，5s，5”’，2“，它们具有由网状基板，棘状直立，杆等组成的三维立体鳞片。卵形和东方异尖线虫的细胞在形状上不同于所描述的异尖线虫的其他种类，但为卵圆形。此外，这两个物种的体鳞片的超微结构与其他异种不同：卵形异种的体鳞相对简单，而东方异种体鳞的超微结构较复杂。
Abstract Two new armoured dinoflagellate species, Heterocapsa ovata Iwataki & Fukuyo sp. nov. and Heterocapsa orientalis Iwataki, Botes & Fukuyo sp. nov., are described, and their body scale and cell morphology are illustrated using light, fluorescence, scanning electron and transmission electron microscopy. These species possess a thecal plate arrangement that is typical of the genus Heterocapsa: Po, cp, 5′, 3a, 7″, 6c, 5s, 5″′, 2″″; and they have triradiate three-dimensional body scales consisting of a reticulated basal plate, spine-like uprights, bars, etc. The cells of H. ovata and H. orientalis are not similar in shape to other described species of Heterocapsa, but are ovoid. In addition, the ultrastructure of the body scales of the two species is different from other Heterocapsa species: relatively simple in H. ovata, but more complex in H. orientalis.
