Revisão das espécies de Ceroplastinae Atkinson (Hemiptera, Coccoidea, Coccidae) do Estado de São Paulo, Brasil

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. Espécies redescritas: C. agrestis Hempel, 1932; C. cassiae (Chavannes, 1848); C. cirripediformis; C. deodorensis Hempel, 1900; C. diospyros Hempel, 1928; C. floridensis Comstock, 1881; C. flosculoides Matile-Ferrero, 1993; C. formicarius Hempel, 1900; C. formosus Hempel, 1900; C. grandis Hempel, 1900; C. gregarius Hempel, 1932; C. iheringi Cockerell, 1895; C. janeirensis; C. lucidus; C. purpureus Hempel, 1900; C. quadratus Green, 1935; C. speciosus Hempel, 1900; C. stellifer e C. variegatus Hempel, 1900. São designados lectótipos e paralectótipos para C. agrestis, C. deodorensis, C. diospyros, C. formosus, C. purpureus, C. speciosus e C. variegatus e um neótipo para C. cassiae.

Impacto do acordo de cooperação do Conselho Nacional de Pesquisas (CNPq) com a National Academy of Sciences - (NAS)

In the beginning of the 1960's, the university education in chemistry, in Brasil, represented only a professional preparation, with no official post-graduate teaching and research, as yet. The name Federal University Rio de Janeiro, evolved, since January 30, 1959, from University of Brazil, RJ, to Federal University of Guanabara, which, on August 20, 1965, became the Federal University of Rio de Janeiro. With the Resolution nº 4, of the University direction, the first Institute of Chemistry was created, to include the Centers of Mathematical and Natural Sciences, and the Medical Sciences. The strictu sensu's system was established only in 1961.

Comparison of scientists of the Brazilian Academy of Sciences and of the National Academy of Sciences of the USA on the basis of the h-index

A new scientometric indicator, the h-index, has been recently proposed (Hirsch JE. Proc Natl Acad Sci 2005; 102: 16569-16572). The index avoids some shortcomings of the calculation of the total number of citations as a parameter to evaluate scientific performance. Although it has become known only recently, it has had widespread acceptance. A comparison of the average h-index of members of the Brazilian Academy of Sciences (BAS) and of the National Academy of Sciences of the USA (NAS-USA) was carried out for 10 different areas of science. Although, as expected, the comparison was unfavorable to the members of the BAS, the imbalance was distinct in different areas. Since these two academies represent, to a significant extent, the science of top quality produced in each country, the comparison allows the identification of the areas in Brazil that are closer to the international stakeholders of scientific excellence. The areas of Physics and Mathematics stand out in this context. The heterogeneity of the h-index in the different areas, estimated by the median dispersion of the index, is significantly higher in the BAS than in the NAS-USA. No elements have been collected in the present study to provide an explanation for this fact.
