【Abstract】 Ctenophthalmus (Euctenophthalmus) acutilobatus, sp. nov. Diagnosis. The new species (fig. 1) is allied to C. (E.) crudelis, both are knownfrom females only, and the new species is readily distinguishable by the narrower andlonger dorsal lobe of the apical margin of sternum Ⅶ, the wider and shallow sinusbelow the lobe. Types. Holotype, 3.6 mm, and paratypes 2 were all taken off Myospalaxfontanieri from Ruoerge, Sichuan (elev. 2500m) in August and September, 1960.Holotype nnd one paratype are deposited in the collection of the Health and Antiepi-demic Station of Sichuan, and one paratype in the collection of the Academy ofMilitary Medical Sciences, P. L. A. Doratopsylla coreana sichuanensis, ssp. nov. Diagnosis. The new subspecies (figs. 2-4) is distinguishable from the othersubspecies by the following characters: 1, the movable process is much shorter, and alittle higher than fixed process; 2, there is an angular process on the anterior marginof the lower portion of the movable process; 3, the length of the posterior lobe of thefixed process is about twice as its width; 4, the dorsal lobe of the apical margin of thesternum Ⅶ in female is a little longer than ventral lobe; and 5, the new subspeciesis distributed in northern Sichuan. Types. Holotype, body length 1.9 mm, allotype, 2.0mm, ex Tamiops swinhoeivestitus in October, 1960 and paratypes 3 8, ex Uropsilus soricipes, Soriculushypsibius, Ochotona thibetana and Pteromys volans, from Ruoerge and Pingwu, Sichuan(elev. 2,500-3,500m) in October, 1960 and June, 1979. 1 299 paratypes are depos-ited in the collection of the Academy of Military Medical Sciences P.L.
