【Abstract】 The present paper gives a report on three species of the genus Typhlodromus from Fujian province,including the descriptions of a new species and the male of Typhlodromus serrulatus Ehara which is reported for the first time, and redescription of Typhlodromus cervix Wu et Li.Type specimens are deposited in the Guangdong Institute of Entomology. Typhlodromus（Anthoseius）coryphus Wu,sp.nov.（figs.1-7） Female:Dorsal shield with 18 pairs of setae,all of which,except D₆,are thick and serrated.Sublateral setae two pairs on interscutal membrane.Peri- tremes extending forwards slightly beyond bases of D₁.Pentagonal ventrianal shield longer than wide（115-125:107.5-110μ）,with 4 pairs of preanalsetae. Chelicera with 4-5 teeth on fixed digit and 3-4 teeth on movable one.Leg Ⅳ with 6 knobbed macrosetae. Male:Dorsal chaetotaxy similar to that of female,but with setae shorter. Setae S₁ and S₂ on dorsal shield.Ventrianal shield 100μ long,140μ wide, with4 pairs of preanal setae.Spermatodactyl as shown in figure 6. Holotype （?）,Allotype（?）,1982.xi.6,Sanming,Fujian province,on Rhus sp.,collected by Jiang Xing-jian;paratypes 2（?）（?）,1982.v-x,Fuzhou and Shaxian,on Gardenia jasminoides Ellis and Euphorbia longan Lour. This species is similar to Typhlodromus machaon（Wainstein）,1977 and Typhlodromus neotransvaaIensis Gupta,1978,but differs from them in the hum her of teeth on the movable digit of the chelicera,It has 3-4 teeth rather than one or none.It differs in having no obvious preanal pore and the shape of spermatheca. Typhlodromus（Anthoseius）serrulatus Ehara（figs 8-9） Male:Dorsal shield densely reticulated,with twenty pairs of setae.Setae S₁ and S₂ on dorsal shield.Peritreme closed to seta D₁.Ventrianal shield not fused with peritrematal shield,with four pairs of preanal setae.Sperm- atodactylas shown in figure 8.3（?）,23（?）（?）,from Fujian,Hubei and Sichuan provinces. TyphIodromus（Anthoseius）serrulatus Ehara was described originally from female collected in Japan.The male of this species is herein described for the first time. Typhlodromus（Paraseiulus）cervix Wu et Li（figs 10-11） Female:Dorsal shield densely reticulated,with 19 pairs of setae,in- cluding dorsocentral setae 6 pairs,median seine 3 pairs and lateral setae 10 pairs.Sternal shield with only two pairs of setae,the third pair is free on interscutal membrane and fourth pair on metasternal shields.
