The present paper deals with one new genus and four new species of Eriophyidae. All measurements are given in μm. The type specimens are deposited in Dept. of Plant Prot., Nanjing Agricultural University, Nanjing, 210095. Pseudocolopodacus gen. nov. (figs. 1～6):Body spindleform, sturdier and flatter. Anterior shield lobes small. Without dorsal tubercles and dorsal seta. Coxa with sternal line and typically coxal seta, legs sturdier and shorter, absent tibia, featherclaw simple. Thanosome with broad dorsal longitudinal trough, Iateral seta and ventral seta complete, without accessory seta, female genitalia coverflap with a longitudinal ribs. This new genus is closely allied to Colopodacus Keifer 1960, but distinguished by the follow characters: new genus without dorsal tubercles and dorsal seta, a longitudinal broad trough on dorsal thanosome obviously. Type species: Pseudocolopodacus aglaiae sp. nov. Female : Body spindleform, flattened and robust, 150～160 long, 80 wide. Rostrum 20 long, projects diagonally downward. Anterior lobe of the shield small and not clear ,shield 45 long, 70 wide, with admedian and submedian line ,without dorsal tubercle and dorsal seta. Coxae with sternal line, coxal seta Ⅰ.Ⅱ.Ⅲ.,4.11,15 long respectly,coxae smooth .Leg Ⅰ19 long, femur 10 long , seta 7 long; genu 3 long, seta 27 long ;tibia absent; tarsus 4 long with 2 setae short and robust; featherclaw simple, 5 rayed, claw straight knobbed. Leg Ⅱ 17 long, seta 9 long; without tibia; tarsus 4 long ,with a stubbed seta; claw with straight knobbed. Thandsome with broad longitudinal trough. The number of tergite and sternites is equality, about 27～30 ring, tergites smooth, sternites with stripe microtubercles. Lateral seta 14 long on sternite 5 . 1st ventral seta 10 long on sternite 12; 2nd ventral seta 7 long on sternite 21; 3rd ventral seta 20 long on sternite 4 from the rear . Telosome without accessory seta. Female genitalia 15 long, 20 wide, coverflap with 12～16 longitudinal ribs, genital seta 7 long, Leaf vagrants. Male: Body 145～150 long, 70 wide. Genitalia 15 wide, genital seta 7 long. Holotype ♀,allotrope ♂,paratype 15♀♀, 2♂♂. 28 Feb., 1994, collected by Cheng Lisheng from Hainan province, Luodong county . Host : Aglaia odorata. Aceria negunis sp. nov.(figs. 7～12). This new species resembles A. quadrimarginis (Dong et xin, 1984), but it differs from the latter in the following characters: the ahead edge of shield appeared arcform ,shield longitudinal line completed, coverflap of female genitalia with longitudinal 10～12 ribs. Holotype ♀, allotype,♂paratype 7♀♀,1♂. Collected in 17 Sept. 1994 from Zhejiang province, Quzhou city by Kuang Haiyuan and Gong Guoji . Host: Vitex negundo. Leaf gall. Aculus shanghaiensis sp. nov. (figs. 13～18). The new species is similar to A. wistarifoliae Keifer 1963, but different from the median line Incomplete, tergites smooth ,the thanosome have round and stripe microtubercles on each side. Holotype♀,allotrope ♂, paratype 20♀♀,6♂♂, 28 Dec. 1994, collected by Kuang Haiyuan ,and Gong Guoji from shanghai city . Host: Wisteria sinensis Vagrant. Abacarus phalaris sp. nov.(figs. 19～24).The new species is similar to A. wyiensis Kuang et Zhuo 1987, but the new species shields without median line and submedian line, opisthosoma dorsum with median and submedian longitudinal ridge extend to telosome ,the number of tergites equilibrate as sternites. Holotype ♀, allotype♂,paratype 14♀♀,3♂♂. Collected by Kuang Haiyuan in 5 June 1992, from Jiangsu province; Nanjing city. Host: Phalaris arrundinacea. Vagrant.
