摘　　要：尼泡马陆属(Nepalella)是泡马陆目(Chordeumatida)中多样性较丰富的属,全世界已记录27种,其中中国已知12种,主要分布在云南、四川、重庆、贵州,且该属多数种类为穴居类型。该文记述采自中国四川省彭州市洞穴内的真穴居尼泡马陆一新种,即何力尼泡马陆(N.helii sp.nov.),这是四川省记录的第四个尼泡马陆属物种。该新种与其近缘种类巨尼泡马陆(N.grandoides Golovatch,Geoffroy&Mauriés,2006)(四川省北川县)的区别在于:(1)体型较小,体长27.5~36.0 mm;(2)雄性第3~5对足的股节近基部具一蘑菇状突起;(3)前生殖肢基板正中部突起明显,呈刺状;(4)后生殖肢基节侧缘中上部具一小型刺状分枝。同时,该文利用分子生物学提取了何力尼泡马陆的DNA,扩增了线粒体细胞色素C氧化酶I亚基基因(cytochrome c oxidase I,COI)的条形码。新的核苷酸序列上传至GenBank数据库,登录号为OL420758。The genus Nepalella currently consists of 27 recorded species in the world,of which 12 species including eight cave-dwellings are known in China,mainly distributed in Yunnan,Sichuan,Guizhou provinces and Chongqing municipality.This paper discribed a new species of the genus collected from a cave in Pengzhou City,Sichuan Province,southwestern China,which is the fourth species of Nepalella recorded in Sichuan.N.helii sp.nov.is very similar to N.grandoides from Beichuan county,Sichuan,but distinguished from the latter in following aspects:(1)The smaller body,ca 27.5-36.0 mm in length;(2)Male femora 3-5 with a mushroom-like protuberance near the base;(3)Anterior gonopod sternum with a high,median,spiniform process;(4)Posterior gonopod colpocoxite attached a small,lateral,spiniform branch.In addition,in this paper,the DNA from a specimen of the new species were extracted using the DNeasy Blood&Tissue kit,and the barcode of the mitochondrial cytochrome oxidase I subunit gene(COI)were amplified.The new nucleotide sequence was uploaded to the GenBank database with accession number OL420758.
