摘 要:本文记述了怪蚤属一新种,订名为隆子怪蚤。该新种在一些特征上很象刺怪蚤。新种与后者的主要区别是:新种♂可动突宽刀形,其前缘角至前端角间较平直,前缘角位置较低;不动突显长,其前缘长度长于或等于可动突前缘角至前端角距离。♀第7腹板后缘下段呈或长或短的后突状。标本于1994年7月采自西藏隆子县,宿主为锡金松田鼠和社鼠。新种即以模式标本采集地(隆子县)命名。Paradoxopsyllus lhuntsensis sp. nov. The new species is rather similar to P. spinosus on many characters, especially as in P. spinosus the male also with a small upturned spine - like process mesad of the base of the upper antepygidial seta. The new species is readily distinguishable from P. spinosus by the following characters: ♂ (1) Movable process of clasper is broad knife-like, its anterior margin between anterior angle and tip angle being rather smooth-straight and the anterior angle is lower, situated on the middle point or slightly low lever. While the anterior angle in P. spinosus is convex strongly, and placed above the middle point of the anterior margin. (2) In new species the fixed process of clasper to be distinctly longer and nearly curved-finger shape, the length of its anterior margin is longer than or equal to the distance of anterior angle to apical angle of the movable process. But fixed process of clasper is shorter distinctly in P. spinosus, the distance of the anterior margin shorter obviously than the distance mentioned above. (3) Apical portion of crochet of aedeagus being nearly peach shape, the ventral margin around convex clearly. But in P. spinosus the ventral margin is shriveled. ♀ (4) The lower portion of apical margin of St. 7 with broad posterior process and without lateral cocave in new species, while there is a nearly square dorsal lobe, under the lobe is a long latero-ventral sinus in P. spinosus. Holotype ♂, measuring 2.9 mm long, paratypes 5 ♂♂, 5 ♀♀ take in July, 1994 ex Pitymys sikimensis and Rattus niviventer from Lhunze (Lhuntse) County (28.18 N, 92.49 E), Tibet of China. All types are deposited in the Medical Entomology Collection of the Beijing Institute of Microbiology and Epidemiology, Beijing, China.
