Nothotylenchus andrassy n. sp. is described and illustrated from moss ( Sphagnum sp.) based on morphology and molecular analyses. Morphologically, this new species is characterized by a medium body size, six incisures in the lateral fields, and a delicate stylet (8-9 µm long) with clearly defined knobs. Pharynx with fusiform, valveless, non-muscular and sometimes indistinct median bulb. Basal pharyngeal bulb elongated and offset from the intestine; a long post-vulval uterine sac (55% of vulva to anus distance); and elongate, conical tail with pointed tip. Nothotylenchus andrassy n. sp. is morphologically similar to five known species of the genus, namely Nothotylenchus geraerti , Nothotylenchus medians , Nothotylenchus affinis , Nothotylenchus buckleyi , and Nothotylenchus persicus . The results of molecular analysis of rRNA gene sequences, including the D2-D3 expansion region of 28S rRNA, internal transcribed spacer (ITS) rRNA and partial 18S rRNA gene are provide for the new species.
基于形态学和分子分析，对从苔藓（泥炭藓属）中发现的安德拉西新小杆线虫（Nothotylenchus andrassy n. sp.）进行了描述和图示。形态上，该新物种的特征为中等体型、侧区有六条侧线、具精致的口针（长8 - 9微米）且瘤突清晰。咽具梭形、无瓣膜、无肌肉且有时不明显的中食道球。基部咽球细长且与肠道偏移；具长的阴门后子宫囊（阴门到肛门距离的55%）；以及细长的、锥形且尖端尖锐的尾。安德拉西新小杆线虫在形态上与该属的五个已知物种相似，即杰氏新小杆线虫（Nothotylenchus geraerti）、中型新小杆线虫（Nothotylenchus medians）、近缘新小杆线虫（Nothotylenchus affinis）、巴克利新小杆线虫（Nothotylenchus buckleyi）和波斯新小杆线虫（Nothotylenchus persicus）。提供了包括28S rRNA的D2 - D3扩增区域、内部转录间隔区（ITS）rRNA和部分18S rRNA基因的rRNA基因序列的分子分析结果，用于该新物种的研究。
