Abstract

Psalteriomonadidae are a small family of anaerobic free-living protists belonging to Heterolobosea, Discoba. We cultured 74 new strains of mostly amoeboid Psalteriomonadidae obtained from mainly freshwater habitats and sequenced their 18S rRNA gene. Based on the phylogenetic analysis and genetic distances, we report multiple novel species, four of which we formally describe based on the light-microscopic morphology (Psalteriomonas minuta, P. australis, P. fimbriata, and P. parva). We also examined the ultrastructure of two Psalteriomonas species using transmission electron microscopy. We transfer Sawyeria marylandensis into the genus Psalteriomonas and synonymize Sawyeria with Psalteriomonas. In addition, we studied the flagellate stage of P. marylandensis comb. nov. for the first time, using light and scanning electron microscopy.

点亮灯笼上的紫檀单胞菌科：揭示紫檀单胞菌属（碟形目：异叶目）内的新多样性

藻单胞菌科（Psalteriomonadidae）是厌氧自由生活原生动物中的一个小家族，隶属于异叶藻（Heterolobosea）、藻类（Discoba）。我们培养了 74 株新菌株，这些菌株主要来自淡水栖息地的变形单胞菌，并对其 18S rRNA 基因进行了测序。根据系统进化分析和遗传距离，我们报告了多个新物种，其中四个物种（Psalteriomonadas minuta、P. australis、P. fimbriata 和 P. parva）是根据光镜形态正式描述的。我们还使用透射电子显微镜检查了两种 Psalteriomonas 的超微结构。我们将 Sawyeria marylandensis 并入 Psalteriomonas 属，并将 Sawyeria 与 Psalteriomonas 异名。此外，我们首次使用光镜和扫描电子显微镜研究了 P. marylandensis comb.

期刊介绍： Articles deal with protists, unicellular organisms encountered free-living in various habitats or as parasites or used in basic research or applications. The European Journal of Protistology covers topics such as the structure and systematics of protists, their development, ecology, molecular biology and physiology. Beside publishing original articles the journal offers a forum for announcing scientific meetings. Reviews of recently published books are included as well. With its diversity of topics, the European Journal of Protistology is an essential source of information for every active protistologist and for biologists of various fields.
