Palaeopsylla opacusa sp. nov. (Figs. 1-4) Only male is known. This new species belongs to brevifrontata-group. Male separable from all members of the brevifrontata-group except P. nushanensis Gong et Li, 1992 by the first spine of genal comb sharply pointed and apical portion of the distal arm of st. IX abruptly narrowed than the base. It differs from nushanensis by the movable process of clasper slender and almost straight, its apex extending beyond the apex of fixed process: the disto-lateral lobe of paramere rounded and swelling; the crochet of aedeagus stouter than that in nushanensis. Holotype , paratype ex Nasillus gracilis nivatus, collected from Mt. Cangshan (25°13’N, 100°00’ E, elevation 3 200m), Dan City, Yunnan Province in November, 1992. Body length: 1.9mm. The type specimens are kept in the institute of Epidemiology of Yun- nan Province. Palaeopsylla nushanensis Gong et Li, 1992 (Figs. 5-8) Distinguished from all other members of the brevifrontata-group, except P. opacusa sp. nov. by the first spine of genal comb sharply pointed and the apical portion of the distal arm of st. IX abruptly narrowed than the base: separable from P. opacusa in the male (the female of P. opacusa is unknown) by the movable process of clasper much broader and shorter, boot-shaped, its apex not extending beyond the apex of fixed process; the crochet of aedeagus more slender than that in P. opacusa; the disto-lateral lobe of paramere undu- lated. Specimens record. 2, 1 ex Nasillus gracilis nivofus, were collected from Mt. Cangshan (25°13’ N, 100°00’E, elevation 3 200m), Dan City, Yunnan Province in November, 1992. Body length: 2.0mm. The specimens are kept in the institute of Epidemiology of Yunnan Province.
