Abstract

A new species of the genus Ficophagus was recovered from the syconia of Ficus pisocarpa from Xishuangbanna, Yunnan province, China. It is described herein as Ficophagus pisocarpae n. sp. and is characterised by possessing the combined characters of a short PUS (6.4-9.3 μm or 0.3-0.4 VBD long), an excretory pore near the head, presence of crustaformeria, amoeboid sperm, three pairs of subventral papillae on the male tail (one pair just adcloacal (P2), one pair halfway between cloacal aperture and tail terminus (P3a), and one pair near tail tip (P4)), rounded male tail tip without mucron, absence of gubernaculum and rose-thorn-shaped spicule with conical rostrum. Ficophagus pisocarpae n. sp. was differentiated from other sequenced species by the partial small subunit (SSU) rRNA gene and D2-D3 expansion segments of the large subunit (LSU) rRNA gene. Phylogenetic analysis with the LSU D2-D3 expansion segment sequence suggested that F. pisocarpae n. sp. is clustered in the same highly supported monophyletic clade with F. annulatae, F. benjamina, F. curtipes and F. microcarpus. It differs morphologically from these species in lateral incisure number, EP position, spicule and uterus morphology and some morphometric characters.

中国松果榕的一种近缘种(线虫纲:松果榕科)

摘要从云南西双版纳的无花果(Ficus pisocarpa)结皮中发现了一新种。本文将其描述为Ficophagus pisocarpae n. spp .，其特征是具有短的PUS (6.4-9.3 μm或0.3-0.4 VBD长)，头部附近有排泄孔，存在甲壳，变形虫精子，雄尾上有三对腹下乳头(一对位于腺管孔(P2)，一对位于腺管孔与尾端中间(P3a)，一对靠近尾尖(P4))，雄尾尖圆形，无茸毛。无小花梗和玫瑰刺状的穗状具圆锥形喙。Ficophagus pisocarpae n. sp.通过部分小亚单位(SSU) rRNA基因和大亚单位(LSU) rRNA基因的D2-D3扩展段与其他已测序的物种区分开来。利用LSU D2-D3扩展段序列进行的系统发育分析表明，F. pisocarpae n. sp.与F. annulatae、F. benjamina、F. curtipes和F. microcarpus属于同一高度支持的单系分支。在侧面切痕数、EP位置、针状体和子宫形态以及一些形态计量学特征上与这些物种存在形态学上的差异。

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.
