This paper reports five species of Phytoseiidae, including four new species and the male of a known species from Fujian. The male of I phiseius dinghuensis is described for the first time. Type speciemens are deposited in the Guangdong Institute of Entomology.

Amblyseius （Amblyseius） wuyiensis, sp. nov. （figs. 6-12） This specie is similar to A. channabasavanni Gupta et Daniel, 1978 and A. mcmurtryi Muma. 1967, but differs from channabasavanni in the dorsal shield being smooth, the fixed digit of chelicera without pilus dentilis and setae M2> L4. It differs from mcmurtryi in the cervix of spermatheca being thicker and longer and in the shape of ventrianal shield.

Male: Unknown. Holotype ♀, paratypes 2♀♀, Shamen city, Fujian Province. 1980. vi. 4, on grass, collected by Wu. 3♀♀, Jianfengling, Hainan Island, 1980. x. 13. on Psi- dium guajava collected by Qian. 2♀♀, Tengchong, Yunnan province, 1980. v, col- lected by Qian. AmbIyseius （Amblyseius） circellatus sp. nov. （figs. 18-22） This species resembles A. （A.） newsami （Evans） 1953, but differs from it in the setae L0 being smooth, a11 setae longer except setae L9 and D1 leg Ⅳ with only one macrosetae, and in the shape of spermatheca. Male: Unknown. Holotype ♀, paratypes, 2♀♀, Jianyang Xian, Dazhulan, 1980. vi. 8 on Ma- chilus thunbergii, collected by Wu.
