摘　　要：在甘肃中南部设置12个样区,对该地区原尾虫的物种多样性进行了研究。通过干漏斗分离、制片、镜检观察对甘肃原尾虫进行鉴定和分类,在6个样区发现原尾虫11种,结合文献记载,甘肃共有16种原尾虫。包括1个甘肃新记录属、4个甘肃新记录种和1个未定名种。檗蚖科有2属3种,仅发现于生态环境保护较好的陇南文县;古蚖科有3属7种;始蚖科有1属1种;夕蚖科有1属2种;日本蚖科有1种,中华雅娃蚖(Yavanna sinensis)是甘肃的新记录种;蚖科有1属2种,包括1个华山蚖属未定名种(Huashanentulus sp.)。古蚖科、檗蚖科为优势类群,华山蚖(H.huashanensis)为广布种。在高海拔、土壤贫瘠和人类活动频繁的6个样区未采到标本。甘肃分布的16种原尾虫中,古北界物种3种,东洋界物种9种,广布种类4种。大部分原尾虫分布在植被良好的东洋界及古北界东洋界过渡地带。在人为干扰较少和环境植被良好的地区,分布的原尾虫物种较丰富;人为干扰严重或环境污染较重的区域未采集到原尾虫。The species diversity of protura was studied based on the sample collection for 12 sampling areas in the mid-southern section of Gansu Province（ Fig. 1,Table 1）. We employed tullgren methods,seal sheet and oil lens observation to identify species. Eleven species were identified in 6 sampling areas,and combining with the historical documentary records,total of 16 species were found in the sample region. Among them,one new genus and 4 new species are recorded first time in Gansu Province（ Table 2）. Seven species in 3 genera under Eosentomidae,they they account for 7 /16 of the total number of protura. Seven species in family of Eosentomidae and 2 specoes in family Berberentulidae,they form the dominant group in the fauna of protura;while species H. huashanensis is widely distributed in the sampled region. No any specimen was collected in 6sampling areas located in high-altitude region due to soil depletion and frequent human disturbance. Among the16 species,3 are the Palearctic species,9 are the Oriental and 4 species are widely distributed in bothPalearchic and Oriental region. The majority species of the protura distributes in the region with good vegetation throughout the Oriental and the transitional zone between the Oriental and the Palearctic. All the protura species were collected in the areas with thick vegetation and less human interference in Gansu. No protura specimen was found in the areas with pollution and heavy anthropogenic interference.
