摘要

摘要在中国栎树根际中发现了郑氏长枝。该新种雌性体长中等(3.2 ~ 4.0 mm)，唇部略偏置，前部扁平，因收缩而与身体其他部分隔开，漏斗状双侧囊，距前端57.0 ~ 60.0 μ m处有一个简单的引导环，花柱由中等长度的齿柱(108.0 ~ 139.0 μ m)和弱发育的齿孔(56.0 ~ 68.0 μ m)组成，咽球长61.0 ~ 74.0 μ m，发育良好的偏置心。尾巴短而圆锥形，末端宽而圆。该物种有四个幼年发育阶段(J1-J4)，未发现雄性。新种的基质编码为:A45-B23-C5-D2-E1-F2-G1-H1-I1-J1-K5。利用ITS1和28S D2-D3 rRNA基因序列对新种进行了分子表征。系统发育分析表明，郑氏L. n. sp.与中国大陆所描述的若干种属在类群上，分别与荔枝L.、diadecturus .和核桃L.聚类。

Description of Longidorus zhengi n. sp. (Nematoda: Longidoridae) from the rhizosphere of Quercus aliena in China

Summary Longidorus zhengi n. sp. was recovered in the rhizosphere of Quercus aliena in China. The new species is characterised by medium-length females (3.2-4.0 mm), lip region slightly offset, anteriorly flat and separated from the rest of the body by constriction, funnel-shaped amphidial pouches, a simple guiding ring located at 57.0-60.0 μ m distance from the anterior end, stylet composed of a moderately long odontostyle (108.0-139.0 μ m) and weakly developed odontophore (56.0-68.0 μ m), 61.0-74.0 μ m long pharyngeal bulb, well-developed offset cardia, and a short conical tail with widely rounded terminus. The species has four juvenile developmental stages (J1-J4) and no male was found. The matrix codes of the new species are: A45-B23-C5-D2-E1-F2-G1-H1-I1-J1-K5. The new species was molecularly characterised using ITS1 and 28S D2-D3 rRNA gene sequences. The phylogenetic analyses placed L. zhengi n. sp. with several species described from the mainland of China, which were clustered with L. litchi , L. diadecturus and L. juglans .

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.
