摘要:

由于生活史特殊以及分类学历史复杂, 国内外有关梨甲藻科物种的分类学研究比较少。本研究通过形态分类学方法, 详细阐述了梨甲藻物种的分类学历史沿革, 对我国海域的11种梨甲藻科物种的孢囊进行了分类学研究。我们认为其中的1种应隶属于球甲藻属(Dissodinium), 其余10种可归为梨甲藻属(Pyrocystis)(包括2个变种, 2个变型), 对每个物种都进行了详细的形态学描述, 认为拟新月球甲藻(Dissodinium pseudolunula)与新月梨甲藻(Pyrocystis lunula)、优美梨甲藻(Pyrocystis elegans)与粗梨甲藻(Pyrocystis robusta)的分类学关系还需要进一步研究。

Abstract:

Taxonomic studies on the family Pyrocystaceae are scarce because of the group’s special life cycle and complicated taxonomic history. In this study, a detailed literature review of Pyrocystaceae is presented, and cysts of 11 species belonging to Pyrocystaceae are studied using morphological taxonomy methods. We believe that one species should be moved to genus Dissodinium, the remaining 10 species (including 2 varieties and 2 formas) are more reasonably kept in genus Pyrocystis. We also present a morphological description of each species. Furthermore, we believe that the taxonomic relationships between Dissodinium pseudolunula and Pyrocystis lunula, P. elegans and P. robusta require further study.
