高黎贡山柳氏蚤属一新种记述(蚤目:多毛蚤科)

A NEW SPECIES OF THE GENUS LIUOPSYLLA FROM MT. GAOLIGONG, CHINA (SIPHONAPTERA: HYSTRICHOPSYLLIDAE)

本文记述柳氏蚤属Liuopsylla一新种,杆形柳氏蚤L.clavula sp.nov.。新种与锥形柳氏蚤L.conica Zhang,Wu et Liu,1985接近,但有明显区别。标本采自云南高黎贡山多齿鼩鼹(Nasillus gracillis)体上。

Liuopsylla clavula sp. nov. (figs. 1-6)This new species in male is related to L. conicu Zhang, Wu et Liu, 1985 but readily separable from the latter by following important characters: 1) the t. Ⅷ with its length slightly smaller than width of the median portion, instead distinctly larger; 2) the apical process of st. Ⅷ clavated (hence the new species is named), instead .of cone-shaped; 3) the immovable process of clasper nearly eqilateral triangle, its antirior margin without bristle; 4) the movable process of clasper nearly upside-down boot-shaped, instead of bananashaped; 5) the posterior margin of distal arm of st. Ⅸ with a ventral dilation distinctly and with a lot of bristles as well as small spiniforms.Female unknown.Holotype male, paratypes 2 males (body length 2.5-2.6 mm) separately off Nasillus gra-cilis, collected in 15-30, October, 1985 from Gaoligong Mountain (elevation about 2600-3200m), Gongshan County, North-western region of Yunnan Province and are deposited in the Research Institute of Epidemic Diseasis of Yunnan Province.
