Abstract

A new nematode species, Phasmarhabditis villasmundi sp. n., was isolated from land gastropods in the Villasmundo-S. Alfio Nature Reserve in Syracuse Province, Sicily. Phasmarhabditis villasmundi sp. n. is characterised by the presence of males and females in the population and is recognised mainly by a conical female tail with prominent phasmids at its mid-length, spicules ca 82 μm long with a hole at the distal tip, infective juveniles with an average length of 773 μm and the distinct molecular characteristics of the new species. It is the second member of the genus described from Italy apart from P. apuliae Nermut’ et al., 2016 and is morphologically closest to this species. However, phylogenetic analyses based on ITS and D2-D3 LSU placed P. villasmundi sp. n. close to European P. neopapillosa and P. hermaphrodita, while P. apuliae appeared to be related to P. bohemica and the New World’s P. californica.

西西里岛锡拉丘兹省“Villasmundo - S. Alfio洞穴复合体”自然保护区陆生腹足动物的感染

从Villasmund-S陆生腹足类中分离到一个新的线虫物种，即维拉斯蒙迪Phasmarhabditis villasmundi sp.n。西西里锡拉丘兹省的阿尔菲奥自然保护区。villasmundi Phasmarhabditis sp.n.的特征是种群中存在雄性和雌性，主要通过一条圆锥形雌性尾巴来识别，该尾巴的中间长度有突出的phasmids，约82μm长的针状物，末端有一个洞，平均长度为773μm的感染性幼体，以及新物种的独特分子特征。它是除P.apuliae Nermut’et al.，2016之外，在意大利描述的第二个属成员，在形态上与该物种最接近。然而，基于ITS和D2-D3 LSU的系统发育分析表明，维拉斯蒙迪P.villasmundi sp.n与欧洲P.neopapillosa和P.hermachrodita接近，而P.apuliae似乎与P.bohemica和新大陆的P.californica有关。

期刊介绍： Nematology is an international journal for the publication of all aspects of nematological research (with the exception of vertebrate parasitology), from molecular biology to field studies. Papers on nematode parasites of arthropods, and on soil free-living nematodes, and on interactions of these and other organisms, are particularly welcome. Research on fresh water and marine nematodes is also considered when the observations are of more general interest. Nematology publishes full research papers, short communications, Forum articles (which permit an author to express a view on current or fundamental subjects), perspectives on nematology, and reviews of books and other media.
