摘要

本文介绍了一项研究的结果，并描述了一种新的颗粒虫--Pelomyxa pilosa sp.该物种发现于圣彼得堡（俄罗斯）附近的一个池塘的底层沉积物中，研究人员使用光学、免疫荧光和透射电子显微镜对其进行了检验。根据其形态特征，包括运动方式、大量鞭毛的存在、细胞质的组织以及强制性原核内生虫的存在，将其归入 Pelomyxa Greeff, 1874 属。通过细胞表面大量原核外寄生虫的特异性存在以及核器的组织结构，可以很容易地将该新物种与同类区分开来。该物种的核物质形成一个空心球体，由形状和大小各异的紧密相邻的斑块组成，周围是颗粒状物质。

Unusual archamoeba Pelomyxa pilosa sp. nov. (Amoebozoa: Archamoebae: Pelobiontida): a light and electron microscopic study

This paper presents the results of a study and describes a new species of pelobionts, Pelomyxa pilosa sp. nov. (Archamoebae: Pelobiontida). This species was found in the bottom sediments of a pond near St Petersburg (Russia) and was examined using light, immunofluorescence, and transmission electron microscopy. It is placed in the genus Pelomyxa Greeff, 1874 based on a combination of morphological features, including the mode of locomotion, the presence of numerous flagella, the organisation of the cytoplasm, and the presence of obligate prokaryotic endocytobionts. The new species can be easily distinguished from congeners by the specific presence of numerous prokaryotic ectobionts on the cell surface and the organisation of the nuclear apparatus. The nucleolar material in this species forms a hollow sphere consisting of tightly adjacent patches of various shapes and sizes, surrounded by granular material.

期刊介绍： Zoosystematica Rossica is an international journal for publication of papers on any aspects of systematic zoology, in all groups of animals, both extant and fossil, from all over the World. The journal is published in English and focuses on the descriptions of new taxa, revisions and reviews, nomenclature, theories and methods of taxonomy and phylogeny, interesting new faunal records, catalogues and checklists, identification keys, phylogenetic relationships and zoogeography. Faunistic articles are published in a limited way and only if they contain new records for large geographical regions and are important for zoogeography or taxonomy.
