ABSTRACT In this study a new aphid species of the genus Lizerius Blanchard, 1923 (Hemiptera: Drepanosiphidae) is described. Samplings were carried out in the municipalities of Porto Ferreira and Pedregulho, state of São Paulo, Brazil, over plants of Persea americana Mill, 1768 and Terminalia brasiliensis Spreng, 1825. Morphological characteristics of apterous and alate are described and represented by drawings.

As espécies de Ceroplastinae (Hemiptera, Coccoidea, Coccidae) que ocorrem no Estado de São Paulo são revisadas. São estudadas 36 espécies de Ceroplastinae, das quais 9 são sinonimizadas, 8 espécies novas são descritas e 19 são redescritas. Ceroplastes campinensis Hempel, 1901, C. bicolor Hempel, 1901, C. excaericae Hempel, 1912 e C. farmairii (Signoret, 1866), mencionadas para o Estado de São Paulo, não foram examinadas, devido a não localização do material tipo ou de outros exemplares. Nossos estudos indicaram que C. albolineatus Cockerell, 1894 e C. confluens Cockerell & Tinsley, 1898 foram erroneamente citadas por Hempel, 1900 para o estado de São Paulo. Coccus stellifer Westwood, 1871, atualmente Vinsonia stellifera (Westwood, 1871), é transferida para gênero Ceroplastes como Ceroplastes stellifer (Westwood, 1871) n. comb. C. flosculoides Matile-Ferrero, 1993 é registrada pela primeira vez para o país e C. cassiae (Chavannes, 1848), C. deodorensis Hempel, 1937, C. formosus Hempel, 1900 e C. quadratus Green, 1935 são registradas pela primeira vez no Estado de São Paulo. Ceroplastinae é agora representada por 31 espécies no Estado de São Paulo, todas incluídas no gênero Ceroplastes. Ilustrações e uma chave para espécies são incluídas. Novos sinônimos: C. formicarius Hempel = Ceroplastes communis Hempel, 1900 n. sin.; C. janeirensis Gray, 1828 = Ceroplastes psidii (Chavannes, 1848) n. sin. = C. simplex Hempel, 1900 n. sin.; C. cirripediformis Comstock, 1881 = C. cultus Hempel, 1900 n. sin. = C. cuneatus Hempel, 1900 n. sin. = C. rarus Hempel, 1900 n. sin e C. rotundus Hempel, 1900 n. sin.; C. lucidus Hempel, 1900 = C. novaesi Hempel, 1900 n. sin.; C. grandis Hempel, 1900 = C. rhizophorae Hempel, 1918 n. sin. Novas espécies descritas: C. acutus sp. nov.; C. bragai sp. nov.; C. coronatus sp. nov; C. glomeratus sp. nov; C. jordanensis sp. nov.; C. minimus sp. nov.; C. solanaceus sp. nov.; C. willinkae sp. nov.

The species of Ceroplastinae (Hemiptera, Coccoidea, Coccidae) from the state of São Paulo are revised. Thirty-six species are studied, 9 are synonymyzed, 8 new species are described and 19 known species are redescribed. Ceroplastes campinensis Hempel, 1901, C. bicolor Hempel, 1901, C. excaericae Hempel, 1912 and C. farmairii (Signoret, 1866) were not studied because the type material or other specimens were not found. Our studies indicate that C. albolineatus Cockerell, 1894 and C. confluens Cockerell & Tinsley, 1898 were erroneously cited by Hempel, 1900 as occurruing in the state of São Paulo. Coccus stellifer Westwood, 1871, currently Vinsonia stellifera (Westwood, 1871), is transferred to Ceroplastes as Ceroplastes stellifer (Westwood, 1871) n. comb. Ceroplastes flosculoides Matile-Ferrero, 1993 is recorded for the first time in Brazil and Ceroplastes cassiae (Chavannes, 1848), C. deodorensis Hempel, 1937, C. formosus Hempel, 1900 and C. quadratus Green, 1935 are recorded for the first time for state of São Paulo. The Ceroplastinae is now represented by 31 species in the state of São Paulo, all included in the genus Ceroplastes. Identification key and illustrations for species are included. New synonyms are proposed: C. formicarius Hempel = Ceroplastes communis Hempel, 1900 n. syn.; C. janeirensis Gray, 1828 = Ceroplastes psidii (Chavannes, 1848) n. syn. = C. simplex Hempel, 1900 n. syn.; C. cirripediformis Comstock, 1881 = C. cultus Hempel, 1900 n. syn. = C. cuneatus Hempel, 1900 n. syn. = C. rarus Hempel, 1900 n. syn and C. rotundus Hempel, 1900 n. syn.; C. lucidus Hempel, 1900 = C. novaesi Hempel, 1900 n. syn.; C. grandis Hempel, 1900 = C. rhizophorae Hempel, 1918 n. syn. New species described are: C. acutus sp. nov.; C. bragai sp. nov.; C. coronatus sp. nov; C. glomeratus sp. nov; C. jordanensis sp. nov.; C. minimus sp. nov.; C. solanaceus sp. nov.; C. willinkae sp. nov. Redescribed species are: C. agrestis Hempel, 1932; C. cassiae; C. cirripediformis; C. deodorensis; C. diospyros Hempel, 1928; C. floridensis Comstock, 1881; C. flosculoides; C. formicarius Hempel, 1900; C. formosus Hempel, 1900; C. grandis; C. gregarius Hempel, 1932; C. iheringi Cockerell, 1895; C. janeirensis; C. lucidus; C. purpureus Hempel, 1900; C. quadratus; C. speciosus Hempel, 1900; C. stellifer n. comb. and C. variegatus Hempel, 1900. Lectotypes and paralectotypes of C. agrestis, C. deodorensis, C. diospyros, C. purpureus, C. formosus, C. speciosus and C. variegatus and a neotype for C. cassiae are designated.

Greenidea ficicola Takahashi (Hemiptera: Greenideidae) foi coletado pela primeira vez na região Neotropical no município de São Carlos, região sudeste do Brasil. Foram encontradas formas ápteras em Ficus microcarpa L. (Moraceae) em setembro de 2003 e setembro de 2004.

Greenidea ficicola Takahashi (Hemiptera: Greenideidae) is recorded in the Neotropical Region. G. ficicola was collected in the municipality of São Carlos, São Paulo State, Southeastern Brazil. The specimens are apterous forms collected on Ficus microcarpa L. (Moraceae) leaves in September 2003 and September 2004.

Hyadaphis foeniculi (Passerini, 1860) (Hemiptera: Aphididae) tem sido observado causando danos à cultura de erva-doce, Pimpinella anisum L., na região do agreste meridional de Pernambuco. Este é o primeiro registro da espécie no Estado.

Hyadaphis foeniculi (Passerini, 1860) (Hemiptera: Aphididae) was observed causing damage on anise crop, Pimpinella anisum L., in the Meridional "Agreste" region of Pernambuco State, Brazil. This is the first report of this species in the region.

Females of Orphulella punctata (de Geer, 1794) were captured in the field and kept in cages with food and boxes filled with moist soil for oviposition. The eggs, macerated with 0,85% saline solution and centrifugated, were used as the immunizing antigen for obtention of the specific antiserum (AS-O). Rabbits were immunized by the linphonodule injection method with two injections of this antigen, with an interval of 15 days between the 1st and 2nd inoculations. Serological tests were performed using double diffusion in agar gel with homologous and heterologous antigens. Specific serological reactions were obtained 14 days after the 1st inoculation. The antiserum of the 30th day gave 5, 2-4 and 1-4 precipitation lines respectively with eggs, female and male antigen. Such differences can be attributed to the high specificity of AS-O. Positive reaction was observed with arachnids and mirmeleontids captured in the field, indicating the predation on O. punctata.

Serological techniques were used to study Orphulella punctata (De Geer) predators. For preparation of antiserum, rabbits were immunized by the limphonodule injection method with antigens obtained from O. punctata male. Serological tests were performed using double diffusion in agar gel. Specific serological reactions were obtained 13 days after the 1st inoculation. After the 2nd inoculation 5 precipitation lines were observed. In the reactions with female antigens there were 2-4 lines, while egg antigens showed 2 lines. These variations in the number of lines were attributed to different physiological states and to ontogeny. Positive reactions were observed for spiders and chrysopids captured in the field.
