摘　　要：记述从湖北省长江三峡以南巴东县绿葱坡海拔1750m落叶阔叶林中捕获的猪尾鼠Typhlomys cinereus体上采到的盲鼠蚤属Typhlomyopsyllus Li et Huang,19801新种,巫峡盲鼠蚤Typhlomyopsyllus wuxiaensis sp.nov.。新种以其独特的可动突形态和宽大卵圆形交配囊袋部及环形骨化增厚脊与该属已记录的4种盲鼠蚤均不同,而其它特征♂仅与洞居盲鼠蚤T.cavaticus Li et Huang,1980、♀与刘氏盲鼠蚤T.liui Wu et Liu,2002相近,但依其雌、雄两性变形节的形态可与后2种区别。文后就新种与近缘种的关系和盲鼠蚤属的蚤类地理分布等问题进行了讨论。The paper deals with a new species of Typhlomyopsyllus Li et Huang, 1980, from Hubei Province, China.Typhlomyopsyllus wuxiaensis sp.nov. （Figs.1-9）Diagnosis. The movable process of male clasper of new species is burin-shaped, and its apical margin is wide and nearly oblique truncate, the perula of bursa copulatrix of female is bounty egg-round with a ring-shape sclerotization, these characteristics are different from all the other four species of Typhlomyopsyllus Li et Huang, 1980.

Ⅶ has distinct angle and backward convex, all those characteristics are different from the latter ones（Table 1）.Holotype ♂, body length 2.4 mm, paratypes 1 ♂, 2 ♀♀, body length 2.5-3.4 mm. Holotype and paratypes 1 ♂ collected from Typhlomys cinereus from Lucongpo, Badong County （30.47°N, 110.11°E; alt. 1 750 m）, South of Gorges of Yangtse River in Hubei Province on 15 Apr. 2003. Another paratypes 2 ♀♀ were collected from the same host and place on 16 Nov. 2009 which habitating in deciduous forest. Holotyp and one female paratype are deposited in the Medical Entomology Collection, Institute of Microbiology and Epidemiology, AMMS. One male and one female paratypes are deposited in the Institute of Infectious Diseases, Hubei Academy of Preventive Medical Sciences.Etymology. The new species is named from the Wuxia of the
