The Chinese soft scale species in the genus Coccus Linnaeus, 1758 (Hemiptera: Coccomorpha: Coccidae) were studied. Coccus cambodiensis Takahashi and the Malaysian species C. cameronensis Takahashi are considered to be non-congeneric with Coccus hesperidum Linnaeus, 1758, the type species of Coccus, and are transferred to Prococcus Avasthi, 1993, as Prococcus cambodiensis (Takahashi, 1942), comb. n. and Prococcus cameronensis (Takahashi, 1952), comb. n. The generic diagnosis of Prococcus is revised. In the genus Coccus, two new species are described and illustrated based on adult females: Coccus nanningensis Cao & Feng, sp. n. from Guangxi, China, on Ficus carica (Moraceae), and Coccus cephalotaxus Cao & Feng, sp. n. from Shannxi, China, on Cephalotaxus sinensis (Taxaceae). Identification keys to separate adult females of Prococcus from Coccus, the 14 species of Coccus found in China, and all three species of Prococcus are provided.

Two new species (Kuverahuoditangensissp. n.andKuveralongwangshanensissp. n.) in the family Cixiidae from China are described and illustrated. The generic characteristics are redefined. A checklist to all species ofKuveraworldwide and an identification key to the Chinese species are provided. A map of the geographic distribution ofKuveraspecies is also provided.

A new species of armoured scale insect, Megacanthaspisguiyangensissp. nov. is described and illustrated. The new species is morphologically similar to M.hangzhouensis. Megacanthaspisguiyangenis infests leaves of Oligostachyumlubricum in China. A key to all eight species of Megacanthaspis now known is provided.

Saissetia kunmingensis Cao & Feng, sp. nov., a member of the genus Saissetia Kanda, 1960, is a new species in China that is described and illustrated in this study, based on adult females. This species was found on Osmanthus fragrans (Oleaceae) plants from Kunming, Yunnan Province (China). An updated key to females of the eight species of Saissetia which occur in China was developed.

The adult female of a new species of soft scale Saissetiapuerensis Zhang & Feng, sp. n. is described and illustrated from the genus Saissetia Deplanche, 1859. This species was collected on Lithocarpusuvariifolius (Hance) in Yunnan province, China. A key is provided to separate adult females of all Saissetia species known from China. A table is provided showing the distribution of Saissetia in various zoogeographical regions throughout the world.

Two new species (Kuverahuoditangensissp. n. and Kuveralongwangshanensissp. n.) in the family Cixiidae from China are described and illustrated. The generic characteristics are redefined. A checklist to all species of Kuvera worldwide and an identification key to the Chinese species are provided. A map of the geographic distribution of Kuvera species is also provided.

A new species of armoured scale insect Parlatoria menglaensis sp. n. is described and illustrated which infests leaves of Cinnamomum camphora in China. A key to the Parlatoria species occurring in China is provided.

Two new species of armored scale, Megacanthaspis hangzhouensis Wei & Feng, sp. n. and M. hainanensis Wei & Feng, sp. n. are described and illustrated from specimens collected from China. A key to adult female of Megacanthaspis species is provided.

This paper reviews the cixiid planthopper genus Oecleopsis Emeljanov, 1971. Twelve species are recognized in the genus worldwide, of which three new species from China are described and illustrated: O. spinosus sp. nov., O. tiantaiensis sp. nov., O. wuyiensis sp. nov. A key to all known species of this genus is presented.

Prior to this study, only Megapulvinaria maxima (Green) was known from China. However, a new species M. beihaiensis Wang & Feng, sp. n. is described below and M. maxima is redescribed. A key is provided for the five species now placed in this genus.

A new species of armored scale, Pseudaulacaspis zhenyuanensis Wei & Feng, sp. n. is described and illustrated from specimens collected on Spermadictyon suaveolens in China. A key to armored scale species known from China is provided.

One new species of subfamily Sericothripinae (Thysanoptera: Thripidae) is described and illustrated: Hydatothrips longjingensis sp. n., and H. abdominalis (Kurosawa) is newly recorded from China. The following taxonomic changes are established: Sericothrips houji (Chou & Feng) comb. n. (from Hydatothrips).

The three Chinese species of the tropiduchid genus Epora Walker are revised, including one new species, E. biprolata sp. nov. from Hainan Province, China. Morphological description or diagnoses and illustrations for Chinese Epora and an identification key for all nine species worldwide are provided.
