Types are deposited in the Re- search Institute of Endemic Disease Control of Qinghai Province. Rhadinopsylla (ACtenOPhthalmus) ulangensis Cai et Wu, sp. nov. (Figs. 1-4) Diagnosis. The new species is very similar to R. (A. ) dahurica diclinica Tiflov, 1937 in the st. Ⅶ and genitalis of female, but it differs from the latter in the following characters: 1) the labial palp longer, reaching or extending beyond the apex of fore coxa; 2) the genal comb normally with 6 spines; 3) in male, the posterior margin of st. Ⅷ with a deeper si- nus, and dosal lobe longer. Holotype, 2. 5mm long, paratype ♀, 2. smm long, off Lagurus luteus in Septem- ber, 1977 from Ulan (aft. 3 000m), West Qinghai;paratypes 30 , 35 ♀♀,from Hus- tugou (aft. 2 800m),West Qinghai in November, 1989, host same as for holotype. Rhadinopsylla (Actenophthalmus) xizangensis Cai, Li et Zheng, sp. nov. (Figs. 5-9) Diagnosis. The new species is easyly separated from all known species of Actenophthal- mus, except R. (A. ) heiseri (McCoy, 1911), by the presence of 6 pairs of lateral bristles on tarsal segment －Ⅴ (occasionally 5 on one side) and the anterior margin of antennal fossa usually bearing 1 stout long bristle between the row of frontal bristles and the row of ocular bristles; it differs from R. (A.) heiseri by the genal comb with 5 spines. Holotype , 2. 3mm long, paratype ♀, 3. 2mm long and paratypes , 1♀, off Ochotona marotis in September, 1976 from Nagou (aft. 4 500m), North Xizang; paratype 1 ♀, off nest of bird in July, 1976, locality same as for holotype.
