云南西北部滇金丝猴一新蚤记述(蚤目:蠕形蚤科)

中国科学院昆明动物研究所王应祥同志于1979年11—12月间从云南德钦的甲午雪山采到一批跳蚤。其中从滇金丝猴（RhinoPithecus bieti Mime-Edwards）体上采到的一种鉴定为蠕形蚤属Vermipsyall Schimkewitsch,1885平行蠕形蚤V.parallela Liu,Wu et Wu,1965下一新亚种,依其宿主命名为平行蠕形蚤金丝猴亚种V.parallela rhinopitheca新亚种。现记述如下。

A NEW FLEA FROM THE GOLDEN MONKEY RHINOPITHECUS BIETI MILNE-EDWARDS FROM NORTHWESTERN YUNNAN

The present paper reports the first flea recorded parasitizing the golden monkey Rhinopithecus bieti Milne-Edwards. It is similar to Vermipsylla parallela Liu, Wu et Wu, 1965 and V. minuta Liu, Chang et Chen, 1974, especially similar to the former. It differs in certain morphological differences and is considered as a new subspecies of V.parallela and is named V.parallela rhinopitheca, subspecies nov. after its host.Diagnosis: (Figs. 1 -6 )( 1 ) The body of the new subspecies is obviously smaller, being 2.5 mm in length in both male holotype and female al-lotype, and being 2.0-2.8 mm and 2.1-3.1 mm in paratypes of five males and five females respectively. Though it is similar to V. minuta by its 1.8-2.2 mm in males and 2.2-3.2 mm in females, while in V. parallela parallela, the males is 3.0-3.3 mm and females 3.46-5.53 mm in length. ( 2 ) Immovable process of clasper short and broad, or even somewhat truncate at its apex, instead of being conical in the other two species. (3) Movable process gradually narrowing from middle to apex which is pointed and curved anteriorly. In the nominated subspecies, the apex is rather blunt and rounded. In V. minuta the anterior margin is long and straight. ( 4 ) Dorsal median lobe of the aedcagus fused with the lateral lobe, with its upper dorsal angle squarishly rounded. In the nominated subspecies, the angle is acute, so that the lobe shows an elongate shape. Besides, the manubrium of clasper is weakly sclerotized, its outline is not very clear. (5) Female, the seventh sternite is more or less square in shape instead of somewhat rectangular as in the other two species.Record: The specimens were collected from Jiawu Snow Mountain of Deqin County, Northwestern Yunnan, off Rhinopithecus bieti Milne-Edward, November-December, 1979, including holotype male, allotype female and five male and five female paratypes. All the specimens are deposited in Guiyang Medical College.The host-relationships are discussed.
