Abstract

Two species of the genus Tricirronema: T. tamdaoense and T. tentaculatum, are studied from agricultural soils of Vietnam. Both species are morphologically and morphometrically characterised based on LM and SEM studies. These species are mainly differentiated by the morphology of the vagina, sigmoid in T. tamdaoense and straight in T. tentaculatum, and males with more robust spicules in T. tamdaoense. SEM studies of both species are provided. Molecular analysis based on 18S and 28S rDNA fragments is included for T. tentaculatum, showing relationship with members of the genus Eucephalobus. In addition, a key to species identification of the genus Tricirronema is included, as well as illustrations and a compendium table with the main measurements of the three species.

重新描述越南的 Tricirronema Siddiqi, 1993（Rhabditida, Bicirronematidae）属的两个种，包括对这两个种的 SEM 研究

研究了越南农业土壤中的两个三尖杉属物种：T. tamdaoense 和 T. tentaculatum。根据 LM 和 SEM 研究，对这两个物种的形态和形态计量学特征进行了分析。这两个物种主要通过阴道的形态来区分，Tamdaoense 的阴道呈乙状，而 T. tentaculatum 的阴道呈直线。提供了这两个物种的扫描电镜研究。tentaculatum 的 18S 和 28S rDNA 片段进行了分子分析，显示了与 Eucephalobus 属成员的关系。此外，还提供了 Tricirronema 属的物种鉴定检索表、插图以及包含三个物种主要测量数据的简表。

期刊介绍： Nematology is an international journal for the publication of all aspects of nematological research (with the exception of vertebrate parasitology), from molecular biology to field studies. Papers on nematode parasites of arthropods, and on soil free-living nematodes, and on interactions of these and other organisms, are particularly welcome. Research on fresh water and marine nematodes is also considered when the observations are of more general interest. Nematology publishes full research papers, short communications, Forum articles (which permit an author to express a view on current or fundamental subjects), perspectives on nematology, and reviews of books and other media.
