摘　　要：本文描述了我国为害樟属的个木虱四个新种:Trioza pseudocinnamomi、T.nigricamphorae、T.camphoricda、T.magnicomphorae,并对种类及分布进行了研究。Among the species of Trioza occurring in South China T. camphorea Sa-saki, T. cinnamomi Boselli and T. parthenaxyli Yang et Li feed on the pla- nts of the genus Cinnamomum, Lauraceae; but only T. cinnamomi has beenrecored and has not been found in our country. The four new Species descri-bed in the present paper are serious pests of Cinnamomum spp. The type specimens are kept in the Insect Collection of Beijing Agricu-ltural University. 1. Trioza pseudocinnamomi, sp. n. (fig. 1) Holotype(?), allotype♀, Guangdong Prov. Guangzhou C., 1984-Ⅰ-14,paratypes 7(?)(?), 11♀♀, same as for holotype; 6♀♀, place as for holo-type, 1984-Ⅲ-27. Host plant: Cinnamomum burmannii (Nees) Bl. (Lauraceae) The new species resembles Trioza cinnamomi (Boselli 1930) but differsfrom the latter in the anus longer, about 1/3 times as long as the dorsal va-lve. 2. Trioza nigricamphorae, sp. n. (fig. 2) Holotype(?), allotype ♀, Zhejiang Prov. Hangzhou C., 1980-Ⅳ-26, pa-ratypes 1(?), 1 ♀, same as for holotype; 5 (?)(?), 9♀♀, Jiangxi Prov.Nanchang C., 1984. Host plant: Cinnamomum camphora (L. )Presl. The new species is similar to Trioza nigra Kuwayama 1910 from TaiwanProv., but differs from the latter in having body longer, male proctiger po-sterior margin strongly produced caudad into a posterior lobes. 3. Trioza camphoricola, sp. n. (fig. 3) Holotype(?), allotype ♀, paratypes 7(?)(?), 23♀♀, Zhejiang Prov.Hangzhou C., 1980-Ⅳ-26. The new species' appearance and parameres resemble that of the Triozacamphorae Sasaki 1910, but the new species is easily distinguished from thelatter by the body longer (camphorae is 1.3-1.7mm, new species is 2.02-2.40mm), proctiger longer and posterior margin produced into a posteriorlobes. 4. Trioza magnicomphorae, sp. n. (fig. 4) Holotype♀, paratypes 3♀♀, Yunnan Prov. Lunan Yi Aut.Co. (1600m), 1981-Ⅲ-19. Host plant: Cinnamomum sp. The new species' venation is similar to that of the Trioze jambolanaeCrawford 1917, but the new species differs from the latter in having thecones sto
