摘　　要：描述了从香港打鼓岭的菠萝（Ａｎａｎａｓｃｏｍｏｓｕｓ）根围土壤中采集到的微针垫刃线虫新种（Ｔｙｌｅｎｃｈｕｓｓｔｙｌｏｌｕｓｎ．ｓｐ．）。此新种以极短的口针（ｓｔｙｌｅｔ＝６．４（６．０～６．５）μｍ）区别于垫刃属中其他已知种。此新种最接近于新最小垫刃线虫（Ｔ．ｎｅｏｍｉｎｉｍｕｓＳａｖｋｉｎａ，１９８９），它们除了口针特征的区别外，还在角质层环纹、排泄孔位置、卵母细胞排列和后阴子宫囊等特征上存在着明显差异。Tylenchus stylolus n.sp.was collected from soil around roots of Ananas comosus inHongkong. The new species can be differentiated from all other species of Tylenchusby its very short stylet(6.4(6.0～6.5)μm).It comes closest to T.neominimusSavkina,1989 in body length(388 ± 28 (364～432)μm),position of metacorpus andvulva(MB = 46 ± 2.7 (43～50);V=67 ± 20(64～70).Besides stylet characteristics,itfurther differs from T.neominimus in the cuticle without annulation,excretory poreat the level of the anterior end of esophageal glands,oocytes arranged in a singlefile and absence of a post vulval uterine sac(in T.neominimus,excretory pore at thelevel of the middle of isthums , oocytes arranged in one to two files;post vulvaluterine sac present)。
