摘　　要：文中记述采自藏东南林芝市农耕区的额蚤属(额蚤亚属)一新种,鼠兔额蚤,新种Frontopsylla(Frontopsylla)ochotona sp.nov.。新种可动突呈半圆形,后缘无钝刺鬃,不动突窄长,约与可动突等高等特征与无裂板额蚤Frontopsylla(Fr.)adixsterna Liu,Shao et Liu,1976较为近似,但可根据不动突的末端后缘斜截形以致末端前后缘不对称;♀第7腹板后缘无深窦,后端部呈截形或弧形的宽叶,第8背板后缘端部具宽窦等特征与后者和该属内其他种相区分。模式标本于2018年11月采自西藏自治区林芝市海拔约3000 m的农耕区,宿主为待定种鼠兔Ochotona sp.、北社鼠Niviventer confucianus和白尾松田鼠Pitymys leucurus。Frontopsylla(Frontopsylla)ochotona sp.nov.is closely related to Frontopsylla(Fr.)adixsterna Liu,Shao et Liu,1976,but can be distinguished by the following characteristics:1.In males,the immutable processes exhibit a wide,finger-like shape with asymmetrical anterior and posterior edges at their ends.The posterior edge of st.Ⅷ lacks a deep depression,and the distal arm of st.Ⅸ is split into two lobes.2.In females,the posterior edge of the st.Ⅶ abdominal plate lacks a deep sinus,but the posterior end has a truncated or arc-shaped broad leaf.The posterior edge of t.Ⅷ has a wide sinus,distinguishing it from F.adixsterna and other species in this genus.The type specimen was collected in Linzhi City,Xizang Autonomous Region of China,in November 2018,from an agricultural area at an altitude of approximately 3000 m.The host species include Ochotona sp.,Niviventer confucianus,and Pitymys leucurus.
