摘要(Abstract):

<正> 在鉴定采自我国西南地区的蚤类标本中,发现副角蚤属(Paraceras Wagner,1916)的两个新种。兹记述如下: 一、宽凹副角蚤Paraceras laxisinus Xie,He & Li新种鉴别特征本新种
1. Paraceras laxisinus Xie, He & Li sp. nov. The new species may distinguished from other members of the genus by the following characters: In male, third tarsus of the hind leg with tufty of long bristles; the movable process of the clasper quadrangular; crochet of aedeagus with an apical tooth-like projection. The female is near to P. sauteri (Roths- child, 1914) , but is separable by the sinus of the 7 th sternite which is much wider, its upper lobe narrower, more or less trigonal and the lower lobe is distinctly shorter than the upper one. Body length, male 3. 6mm, female 2. 9--4. 6 mm. Holotype male, allotype female, and 1 female paratype off Martes flavigula, 2 female paratypes off Vulpes vulpes from Jianchuan, Yunnan; another female paratype off Ratlus edwardsi gigas from Suiyang, Guizhou. The type specimens are deposited in the Research Institute of Epidemic Diseases of Yunnan and Gui- yang Medical College. 2. Paraceras menetus Xie, Chen & Li, sp. nov. This new species may distinguished from the other members of the genus by the following characters: (1) The spines of the pronotal comb never more than 16 on two sides together; the spiracles of the unmodified terga of abdo- men, being about 1/3 the diameter of the eye; (2) In male, the movable pro- tess of clasper is thumb-like, without an anterior-dorsal angle, the longest bristles of the 2nd segment of the anntenna short, never beyond the apex of the club; Ⅱ-Ⅲ tarsi of the hind legs with tufty of bristles short and stout; (3) In female, the posterior-ventral projection of st. Ⅶ narrow, long and trun- cate, which reaches about to the apex of st. Ⅷ. The bulga of spermatheca is short and rather round. Body length, male 2. 3--2. 7 mm. female 2. 3--2. 8 mm. Holotype male, allotype female, 1 male and 1 female paratypes off Menetes berbmorei from Menghai, Yunnan; another paratype male off Rattus flavipectus from Yunxian, Yunnan. All the type specimens are deposited in the research Institute of Epidemic Diseases of Yunnan.
