高黎贡山栉眼蚤属一新种(蚤目:多毛蚤科)

A NEW SPECIES OF CTENOPHTHALMUS FROM MT. GAOLIGONG, WEST YUNNAN (SIPHOMAPTERA: HYSTRICHOPSYLLDAE)

1987年10—12月,我们先后对滇西高黎贡山西坡的独龙江(贡山县)和片马(泸水县)两地进行了蚤类的区系调查,结果发现其中在片马雪山丫口附近采获的栉眼蚤属中华栉眼蚤亚属Ctenophthalmus subgenus Sinoctenophthalmus Hopkins & Rothschild,1966中有新种(此标本于次年4月在当地东坡又采获一批),兹记述如下。

Ctemophthalmus (Sinoctenophthalmus) lushuiensis sp. nov.The new species distinguished from other members of the subgenus except C. (S.) parcus Jordan, 1932 and C. (S.) divormus Jordan, 1932 by the deeper concavity of the apical margin of the movable process of male,In male, it differs from parcus and dinormus in the median of movable processnarrower (usually more than twice as long as its median width); the disto-lateral lobe of paramerc narrower and strongly convex (usually more pointed); the distal arm of st. IX much less than half length of proximal arm; in addition, also differs from the Former species in the posterior apical angle of movable process well developed, and its posterior margin not so convesity: differs from the latter by the median dorsal expansion of paramere broader and shorter, and the apical margin area of movable process strongly sclerotized.In female, it differs from the former species in the apical margin of st. VII with a prominent rounded median lobe and below which the margin is more deeply sinuate; differ from the latter in the t, VIII without distinct unciform sclerotization.Holotype , allotype , paratypes 44 ,33 , ex Eothenomys cachinus, parat-ype 1 ex Neotetracus sinensis cuttingi, collected from Mt.
