A New Species of Baccharomyia (Diptera, Cecidomyiidae) from Baccharis Pseudomiryocephala (Asteraceae) in Brazil
Baccharomyia magna Maia, sp. n., a gall midge (Lasiopteridi) that induces galls on Baccharis pseudomiryocephala (Asteraceae) is described and illustrated based on material from Minas Gerais, Brazil. A key to species is presented.

To determine the insecticidal potential of the plant Baccharis salicifolia, belonging to the family Asteraceae, in fruit flies Anastrepha obliqua, a biological test was carried out on fruit fly feeding using ethanol and aqueous raw leaves extracts of B. salicifolia. The results showed that both crude extracts have an insecticidal activity lower tha...
Clinodiplosis agerati, a new galling species that induces stem galls on Ageratum conyzoides (Asteraceae) is described and illustrated (larva, pupa, male, female and gall) based on material collected in Minas Gerais, Brazil. The new species is compared with the other Neotropical species. This is the first record of the Clinodiplosis inAgeratum.

In the state of Rio Grande do Sul, there are few records of geographical distribution and host plants to species of Tomoplagia Coquillett, as well as other genera of Tephritidae, especially those associated with plants of the family Asteraceae. Here, we report the first occurrence of Tomoplagia rudolphi (Lutz & Lima, 1918) in the state of Rio Grand...

Stephomyia Tavares, 1916 comprises seven species, all Neotropical: S. clavata (Tavares, 1920); S. epeugeniae Gagné, 1994; S. espiralis Maia, 1993; S. mina Maia, 1993; S. rotundifoliorum Maia, 1993; S. tetralobae Maia, 1993; and S. eugeniae (Felt, 1913). In the present study, a cladistic analysis based upon adult, pupa, larva and gall morphological characters as well as host plant data is carried out in order to discuss the monophyly of the genus and the relationships among the known species. The Stephomyia monophyly was supported by eight synapomorphies: five homoplastic characters and three non-homoplastic characters. Analyzes showed S. clavata with great instability within the genus, probably due to lack of larva, pupa and female data, so S. clavata was deactivated in analyze. The topology found was (S. mina ((S. eugeniae + S. epeugeniae) (S. tetralobae (S. rotundifoliorum + S. espiralis)))).
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.
Recent decades have seen increased research interest in the processes and mechanisms related to insect gall richness and host plants. The data set provided here includes 968 records of interactions between galling insects and host plants for the Cerrado biome. The data set comprises 505 species of 222 genera and 67 families of host plants. The botanical families most represented in the data set are Asteraceae, Fabaceae, Myrtaceae, Malpighiaceae, and Melastomataceae, which account for ~48.5% of all records and 52% of the total number of species. The gall‐inducing insects listed in the data set include 48 species of Cecidomyiidae and one species of Tephritidae. This data set is the first to compile inventories of plant‐galling insect communities and information about the diversity and distribution of insect galls and their host plants in the Cerrado. The data set reveals knowledge gaps and opportunities for future research on patterns of diversity and distribution, and provides a basis for generating and testing new ecological hypotheses.
