【Abstract】 This paper reports three new species of Phytoseiidae from Shennongjia, Hubei Province. Measurements are in micrometers. The type specimens are deposited in the Guangdong Institute of Entomology.Typhlodromus (Anthoseius) cervix, sp. nov. (figs. 1-5)This species is similar to Typhlodromus algonquinensis Qant and Typhlodromus (Ty-phlodromus) gracilentus Tseng. It differs from them in the following characters: 1) preanal setae 4 pairs in this species, but 2 pairs in algonquinensis; 2) sternal shield with 3 pairs of setae in this species, but 2 pairs in algonquinensis; 3)peritreme extending to j1 in this species, but extending to j3 in algonquinensis; 4) shape and number of macrosetae on leg Ⅳ of this species different from those of gracilentus; 5) spetmatheca different from one another in these three species. Holotype ♀, paratype 1 ♀, 15. Ⅷ. 1981, on Pinus massoniana Lanb. Phytoseius (Dubininellus) nudus. sp. nov. (figs. 6-9)Similar to phytoseivs (Dubininellus) brevicrinis Switski et Shechter on the smooth basis of seta Z4, the ratio of the relative length of some dorsal setae and the shape of sperma-theca, but distinguished from brevcrinis by the following characters: 1) dorsal shield smooth in this species, as against reticulated in brevicrinis; 2) lengths of setae st, Zs, and Z4 72.5-80 in this species, whereas 41-48 in brevicrinis; 3) setae 22 and Z4 minutely serrulate in this species, while smooth in brevicrinis.Holotype ♀, paratypes 7♀♀, Ⅷ. 1981, on Rosa sp, and Populus wilsonii Schneid.Amblyseius (Amblyseius) subplebeius, sp. nov. (figs. 10-16)This species resembles Amblyseius (Amblyseius) plebeius van der Merw, but can be separated from the latter by the peritreme extending to j3, the relative lengths of setae j1, j3, j6 and J2 and the shape of spermatheca.Holotype ♀ and allotype ♂, paratypes 15 ♀♀ 1 ♂, Ⅷ. 1981, on Glycine max (L.) Merr, Quercus variabilis Bl. and Juglans regia L.更多还原
