Abstract：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.
