Abstract

A nematode diversity survey in Mizoram, India led to the recovery of a known species of the order Mononchida (Animalia: Nematoda). Upon investigation, the species was identified as Iotonchulus longicaudatus (Mononchida: Iotonchidae) based on morphology and morphometrics. Iotonchulus longicaudatus can be characterized by its robust body, tubular buccal cavity with dorsal tooth positioned at midway of buccal length, non-denticulate subventral buccal wall, tuberculated pharyngo-intestinal junction, mono-prodelphic female genital system, filiform tail with well-developed caudal glands and spinneret. Molecular data including the 18S and D2-D3 expansion segment of 28S rDNA sequences were generated for the first time for this species and were further utilized to determine its phylogenetic relationship with other mononchs.

印度米佐拉姆邦长尾线虫的分子特征。

在印度米佐拉姆邦进行的一项线虫多样性调查发现了一种已知的单线虫目（动物：线虫）。经形态学和形态计量学鉴定，该物种为长尾蝽（Iotonchulus longicaudatus）。长尾舌虫体体粗壮，舌腔呈管状，背齿位于舌长中段，舌壁腹下无齿，咽肠交界呈结核状，雌性生殖系统单一发育，尾腺和吐丝器发育良好，尾呈丝状。首次获得了该物种28S rDNA序列的18S和D2-D3扩增段等分子数据，并进一步用于确定其与其他单目鱼类的系统发育关系。

期刊介绍： Systematic Parasitology publishes papers on the systematics, taxonomy and nomenclature of the following groups: Nematoda (including plant-parasitic), Monogenea, Digenea, Cestoda, Acanthocephala, Aspidogastrea, Cestodaria, Arthropoda (parasitic copepods, hymenopterans, mites, ticks, etc.), Protozoa (parasitic groups), and parasitic genera in other groups, such as Mollusca, Turbelleria, etc. Systematic Parasitology publishes fully illustrated research papers, brief communications, and fully illustrated major revisions. In order to maintain high standards, all contributors describing new taxa are asked to state clearly where the holotype is deposited and to make paratypes available for examination by the referees. It is recognized that, in some cases, this may cause problems for the authors, but it is hoped that by adhering to this rule authors may be protected against rapid synonymy of their taxa, and the types will be preserved for posterity.
