RESUMEN
Abstract: Most Neotropical species of Cecidomyiidae (Diptera) have been described from Brazil, but a list of species with occurrence in the country has never been published. Little is known about their distribution and richness in the Brazilian phytogeographic domains. Additionally, a list of host plant species has never been gathered. The present study aims to fill these knowledge gaps and provides an overview of this family in Brazil. For this, data were obtained mainly from the literature, but also from the Cecidomyiidae collection of Museu Nacional and two herbaria (RB and R). Based on the site "Flora do Brasil 2020", botanical names were updated and plant species origin and distribution were verified. A total of 265 gall midge species have been recorded in Brazil, most from the Atlantic Forest (183), followed by Cerrado (60), and Amazon Forest (29). The other phytogeographic domains shelter from five to ten species. Phytophagous gall midges occur on 128 plant species of 52 families, almost all native, being 43 endemic to Brazil (21 endemic to Atlantic Forest, five to Cerrado, and one to Amazon). Although, the taxonomical knowledge is focused on the Atlantic Forest, each domain has its own fauna composition and these informations can be useful for environmental conservational purposes. About 58% of the Brazilian fauna are known only from the type-locality. In order to fill these gaps, it is necessary and important to collect in uninvestigated areas.
Resumo: A maioria das espécies neotropicais de Cecidomyiidae (Diptera) foi descrita do Brasil, mas uma lista das espécies com ocorrência no país nunca foi publicada. Pouco se sabe sobre sua distribuição e riqueza nos domínios fitogeográficos brasileiros. Adicionalmente, uma lista das espécies de plantas hospedeiras nunca foi elaborada. O presente estudo visa preencher estas lacunas de informação e fornecer um panorama geral desta família no Brasil. Para tal, dados foram obtidos principalmente da literatura, mas também da coleção de Cecidomyiidae do Museu Nacional e de dois herbários (RB e R). Com base no site "Flora do Brasil 2020", os nomes botânicos foram atualizados e a origem e distribuição das espécies vegetais foram verificadas. Um total de 265 espécies de cecidomiídeos é assinalado para o Brasil, a maioria da Mata Atlântica (183), seguida pelo Cerrado (60) e Floresta Amazônica (29). Os outros domínios fitogeográficos abrigam de cinco a dez espécies. Os cecidomiídeos fitófagos estão associados a 128 espécies de plantas de 52 famílias, quase todas nativas, sendo 43 endêmicas do Brasil (21 endêmicas da Mata Atlântica, cinco do Cerrado e uma da Floresta Amazônica). Embora o conhecimento taxonômico se concentre na Mata Atlântica, cada domínio tem sua própria composição faunística e estas informações podem ser úteis para a conservação ambiental. Cerca de 58% da fauna brasileira é conhecida apenas da localidade-tipo. Para preencher estas lacunas, é necessário e importante coletar em áreas não investigadas.
RESUMEN
The Tabernaemontana genus belongs to the family Apocynaceae comprising about 100 species spread throughout tropical and subtropical regions around the world including Brazil, which contains around 40 species spread all over its territory. Because of the territorial space and climate diversity, these species already identified in Brazil are the largest collection of Tabernaemontana, which are representative (about 30%) of worldwide distribution. The monoterpene indole alkaloids present as major secondary components in all parts of the plants of the genus Tabernaemontana, have attracted the attention of the scientific community for new alkaloids derivatives and bioactivities. This review covers relevant references about Tabernaemontana species found in Brazil, its geographical distribution, occurrence of monoterpene alkaloids and phytochemical activities. Additional information about the South American species activities are also reported in this review.
