Abstract

A population of the genus Devibursaphelenchus was collected from the inner part of the decaying Persian oak tree (Quercus brantii) from Lordegan city of Chaharmahal va Bakhtiari Province, Iran. The morphological and molecular characters confirmed the new species, namely D. lordeganensis sp. n. The new species is characterised by female body length (768-1026 μm), lip region separated from the rest of the body by a slight constriction, obscure lines on lateral fields, stylet length long, slender, wide-lumened, tripartite, composed of a conus with an aperture about half its length, a conophore about equal with the conus, and a shaft, taller than (conus + conophore) length, lacking basal knobs or swelling, excretory pore ca three metacorpal lengths posterior to the base of the metacorpus, post-uterine sac (PUS) (36-67 μm long; 1.3-3.7 times longer than vulval body diam.), absence or vestigial of rectum and anus, posterior end of the body conical with a rounded tip (in some specimens with a spherical protruded projection at tail tip), males 668 to 815 μm long, presence of two pairs of caudal papillae (P2 and P3), spicule length (15-17 μm) with long and wide bladed condylus, triangular rostrum with a blunt tip and small bursa flap ending at the tail tip. The molecular phylogeny based on 28S rDNA revealed that the new species stands close to D. alienae (LC629160) and D. lini (FJ768944, AM396570). The measurements, line illustrations, light microscopy photographs and phylogenetic analysis are given for the new species. In addition, a key to the species of Devibursaphelenchus is given.

来自伊朗的Devibursphelencus lordeganensis sp.n（Ektaphelenchinae）的描述

从伊朗Chaharmahal va Bakhtiari省Lordegan市腐烂的波斯橡树（Quercus brantii）的内部采集了一个Devibursaphelenchus属种群。形态和分子特征证实了新物种，即D.lordeganensis sp.n。该新物种的特征是雌性体长（768-1026μm），唇部通过轻微的收缩与身体其他部分分离，侧场上的模糊线，探针长度长、细长、宽管腔、三重，由一个孔径约为其长度一半的圆锥组成，一个与圆锥大致相等的锥柄，和一个轴，长度高于（圆锥+锥柄），没有基底结节或肿胀，排泄孔在囊体基部后约三个囊体长，子宫后囊（PUS）（36-67μm长；比外阴体直径长1.3-3.7倍），直肠和肛门缺失或残留，身体后端呈圆锥形，尖端呈圆形（在一些标本中，尾部尖端有一个球形突起），雄性668至815μm长，有两对尾乳头（P2和P3），针状长度（15-17μm），有长而宽的刃状髁，三角形主席台，尖端钝，小法氏囊瓣终止于尾部尖端。基于28S rDNA的分子系统发育研究表明，该新物种与D.alienae（LC629160）和D.lini（FJ768944，AM396570）相近。对新物种进行了测量、线图、光学显微镜照片和系统发育分析。此外，文中还给出了该属植物的一个种键。

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.
