Abstract

Labronema Thorne, 1939 is a large and diverse dorylaimid genus with complicated taxonomy. Two new species, Labronemaporosum sp. nov. and Labronemabidoupense sp. nov. from natural habitats in Vietnam were characterised both morphologically and molecularly (18S rDNA and 28 rDNA), and line drawings and microphotographs are provided. Phylogenetic analyses showed that the new species clustered together with Labronemaferox Thorne, 1939, the type species of the genus. The two new taxa belong to a group of Labronema species with medium body (L = 1.5-2.5 mm) and odontostyle (31-39 μm) length, and a lip region offset by a constriction. Based on morphological and molecular evidence, this study shows that the populations from Vietnam previously identified as L.glandosum Rahman, Jairajpuri, Ahmad & Ahmad, 1986 in fact represent L.porosum sp. nov. Evolutionary relationships of Labronema species are discussed. A key to the species of Labronema with a medium-sized odontostyle (31-39 μm) is provided as well as a list of the species of the genus considered valid.

越南自然公园中发现的 Labronema Thorne, 1939 属的两个新种（线虫纲，Dorylaimidae），附带具有中等大小尾柱的物种的鉴定钥匙。

Labronema Thorne, 1939 是一种大型、多样性、分类复杂的龙利鱼属。对越南自然栖息地的两个新种 Labronemaporosum sp.系统发生学分析表明，新种与该属的模式种 Labronemaferox Thorne，1939 年聚类在一起。这两个新类群属于 Labronema 类群，其体长（L = 1.5-2.5 mm）和尾柄长度（31-39 μm）适中，唇区有一缢缩偏移。根据形态学和分子证据，本研究表明，之前被鉴定为 L.glandosum Rahman, Jairajpuri, Ahmad & Ahmad, 1986 的越南种群实际上代表了 L.porosum sp.讨论了 Labronema 物种的进化关系。提供了具有中等大小尾柱（31-39 μm）的 Labronema 物种的检索表，以及被认为有效的该属物种清单。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
