中国穴居尼泡马陆属一新种（倍足纲，泡马陆目，毛顶泡马陆科）

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。

A new cave species of the millipede genus Nepalella Shear, 1979 (Diplopoda,Chordeumatida, Megalotylidae) from Sichuan,southwestern China

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.
