摘　　要：Two new species of Protura are described:Baculentulus wenyingae sp.nov.and Pseudanisentomon lishuiensis sp.nov.Baculentulus wenyingae sp.nov.is characterized by the combined characters of the presence of foretarsal sensillum b',differentiated sensilla on the maxillary palp,leaf-shaped sensillum on the labial palp,absence of P1a seta on tergites I–VI,eight anterior setae on tergite VI and 4/18 chaetotaxy on tergite VII.An updated key to the 13 Baculentulus species from China is also provided.Pseudanisentomon lishuiensis sp.nov.is characterized by the absence of foretarsal sensillum b'-2,b longer than c,the empodial appendage of II and III leg very short,the tergite I with 12 posterior setae,tergites V–VII lack seta A3,and sternites VIII–X with 2/7-4-4 chaetotaxy respectively.It was compared with the affiliated species P.guangxiensis(Yin&Zhang,1982)in detail.In addition,a checklist and the distribution of 39 Protura species from Zhejiang Province are provided,and the Protura fauna in Zhejiang is also discussed.记述中国浙江省原尾虫2新种:文英巴蚖Baculentulus wenyingaesp.nov.和丽水拟异蚖Pseudanisentomon lishuiensis sp. nov.。文英巴蚖的鉴别特征是:前足跗节具有b’感器,下唇须具有叶片状感器,下颚须的感器形态分化明显,腹部Ⅰ–Ⅵ背板缺P1a毛,第Ⅵ背板具有8根前排刚毛,第Ⅶ背板的毛序为4/18;文中修订更新了巴蚖属中国已知13种的检索表。丽水拟异蚖的鉴别特征是:前足跗节缺b’-2感器,外侧感器b长于c,第Ⅱ和Ⅲ对足的中垫极短小,腹部第Ⅰ背板具有12根后排刚毛,Ⅴ–Ⅶ背板缺A3毛,Ⅷ–X节毛序为2/7-4-4,并与其近似种广西拟异蚖P. guangxiensis (Yin&Zhang,1982)进行了详尽比较。文中提供了浙江省目前已知39种原尾虫的名录及其在浙江省的分布地,探讨了该省原尾虫的区系分布特征。
