摘　　要：1984年、1987年和1988年,作者在贵州省采得一批跳蚤标本,经鉴定,其中额蚤属30个标本与现今存在的该属40多种和亚种均不相同,但与云南的迪庆额蚤指名亚种接近,为一新亚种。文中对该种进行了描述。Frontopsylla (Frontopsylla) diqingensis weiningensis ssp. nov. The new subspecies is near to F. (F. ) d. diqingensis Li et Hsieh, 1974, but could be distinguished from it by the following character : (1) The apex of the immovable process as shown in Fig. 1, is broad and round, and with- out remarkable posterior angle, while in F. d. diqingensis the apex is angu- lar and with a prominent posterior angle. (2) the dorsal margin of the movable process is horizontal but narrower, about 0.6 as broad as long, while in that of F. d. diqingensjs is about 0.7. (3) the gap between the two sets of spiniforms and bristles along the posterior margin of the distal arm of the ninth sternite is longer than that F. d. diqingensis, which is long enough to allow either the upper set or the lower set of bristles to put in. (5) Female: the posterior margin of the seventh sternite as shown in Fig. 4-A. B. C, with a slightly deeper and shallow sinus.
