二刺大锥蚤一新亚种(蚤目:角叶蚤科)

DESCRIPTION OF A NEW SUBSPECIES OF MACROSTYLOPHORA BISPINIFORMA (SIPHONAPTERA: CERATOPHYLLIDAE)

二刺大锥蚤(Macrostylophora bispiniforma Li, Hsieh & Yang)系李贵真等1976年根据云南德钦标本首次记述的。在此以后,作者等先后从本省的剑川、中甸和贡山又采到数批标本。经进一步研究鉴定,认为其中的贡山标本系一新亚种,兹记述如下。

Macrostylophora bispiniforma gongshanensis ssp. nov.The new subspecies is very near to M. b. bispiniforma Li, Hsien & Yang, 1976 but could be distinguished from it by the following characters: In male, 1) the movable process with its middle wider, the dorsal margin with a large spiniform shorter; the upper a spiniform oblique, straighter, and the lower slightly projjcted; upper most a subspiniform on the apex of ventro-posterior process being longer; 2) the base of distal arm of St. Ⅸ with two large spiniforins about equal in size, its ventral posterior margin with a small tooth-like process, without small sinus; 3) the apex of crochet usually rounder; in famle; 4) the posteroventral lobe of st. Ⅶ usually tooth-like; 5) the hill of spermatheca longer, and about same wide from the base to the apex.Holotype (?), allotype (?), paratypes 14(?), 26(?), ex Tamiops swnhoei; other paratypes 1(?), 1(?) separately ex Dremomys lokjiah and Rattus eha collected from Gongshan, Yunnan (2,400-2,800 m.) in October, 1985. Body length: (?) 2.9-3.1 mm; (?) 2.8-3.9mm. All type speci-mens are kept in Research Institute of Epidemic Diseases of Yunnan.
