云南栉眼蚤属一新种(蚤目:多毛蚤科)

A NEW SPECIES OF CTENOPHTHALMUS FROM YUNNAN PROVINCE, CHINA (SIPHONAPTERA: HYSTRICHOPSYLLDAE)

本文记述了从滇西北边陲担打力卡山脉采获的栉眼蚤属一新种——解氏栉眼蚤Ctenophthalmus(Sinoctenophthalmux)xiei。本新种与端凹栉眼蚤Ctenophthalmus(S.)parcus Jordan,1932近缘,但可根据其下唇须,可动突、第九腹板和阳茎端侧叶以及第七腹板后缘的形态等特征与后者区分。

Ctenophthalmus (Sinoctenophtlialmus) xiei sp. nov.This new species is allied to Ctenophthalmus (S.) parcus Jordan, 1932 but differ in the following diagnostic characters: 1) the labial palp reaching only to about two-thirds of fore coxa; in male, 2) the movable process longer (about 2 time as long as wide of middle), the posterior margin not so convex as that of parcus; 3) the distal arm of st. Ⅸ much less than half the length of the proximal arm, its apical margin truncate; 4) the posterior ventral margin of st. Ⅷ without concavity; 5) the disto- lateral lobe,of paramere narrower, and with a ventral apex angle; in female, 6) the apical margin of st. Ⅶ with a large rounded median lobe and below which the margin is more deeply sinuate.Holotype ♂, allotype ♀, paratypes 16♂♂ 12♀♀, ex Eothenomys cachinus; other paratypes 2♂♂ ex E. eleusis collected from Mt.
