“…Studies done in the southeastern region of Brazil have shown the richness of entomogenic galls in restingas (Bregonci et al, 2010;MAIA et al, 2008;MAIA et al, 2014;RODRIGUES et al, 2014) and have described a large diversity of galling insects (MAIA, 1995(MAIA, , 2001(MAIA, , 2007. In general, there are few studies with a focus on richness of gall-inducing insect in the coastal region of southern Brazil, except the articles of Mendonça Jr. et al (2010), performed in restingas of Rio Grande do Sul, and Arriola et al (2016), in restinga formations occurring on dunes in the northeastern portion of the state of Santa Catarina.…”

The restingas are coastal ecosystems over the sandy Quaternary plains. Their vegetation present flora and structure conditioned mainly by edaphic factors. They vary from grasslands, shrub lands up to woody forests. Their environmental conditions, such as water stress and high solar irradiance, may be associated to a high richness of galling. This study aims to identify the insect-plant interactions of the gall type, in a shrub-tree restinga formation at the Acaraí State Park, situated in São Francisco do Sul, Santa Catarina State. The survey was conducted in four plots of 250 x 5 m (5,000 m²) of the PELD/PPBio module, with a sample effort of 32 hours. There were found 56 morphospecies of galls in 31 species of host plants. Lauraceae, Myrtaceae, Melastomataceae, Nyctaginaceae and Calophyllaceae showed the highest number of interactions. Guapira opposita (Nyctaginaceae) and Calophyllum brasiliense (Calophyllaceae) were the major super-hosts. There was a predominance of isolated globoid galls on leaves, induced by Diptera -Cecidomyiidae. Galls on stems were less abundant. The focus of this inventory was restricted to the aerial parts of the plants, which limited the galls records on roots, for which there were records only in adventitious roots of the epiphyte Philodendron surinamense. The richness of galls seems to be proportional to the richness of plant species in this restinga formation. Keywords: Cecidomyiidae; coastal vegetation; plant-insect interaction; super-hosts. RESUMOAs restingas são ecossistemas costeiros que ocupam as planícies quaternárias arenosas. Sua vegetação apresenta flora e estrutura condicionada por fatores edáficos em maior grau. Variam de formações herbáceas, arbustivas, arbustivo-arbóreas a florestas. Suas características ambientais estressantes, como a baixa disponibilidade hídrica e a alta radiação solar, propiciam uma elevada riqueza de insetos galhadores. O objetivo deste estudo foi reconhecer as interações inseto-planta, do tipo galha, na formação arbustivo-arbórea da restinga do Parque Estadual Acaraí, situado em São Francisco do Sul, Santa Catarina. O levantamento foi realizado em quatro parcelas de 250 x 5 m (5.000 m²) do módulo PELD/ PPBio, com esforço amostral de 32 horas. Encontraram-se 56 morfoespécies de galhas em 31 espécies de plantas hospedeiras. As famílias com maior número de interações foram Lauraceae, Myrtaceae, Melastomataceae, Nyctaginaceae e Calophyllaceae. As espécies Guapira opposita (Nyctaginaceae) e Calophyllum brasiliense (Calophyllaceae) foram as principais super-hospedeiras. Houve predominância de galhas globoides isoladas em folhas, induzidas por Diptera -Cecidomyiidae. Galhas em caules foram menos abundantes. O foco do inventário restringiu-se às partes aéreas das plantas, o que limitou o registro de galhas em raízes, sendo registradas apenas em raízes adventícias da epífita Philodendron surinamense. A riqueza de galhas parece ser proporcional à riqueza de espécies vegetais nessa formação de restinga. Palavras-chave: Cecidomyiidae; interação inseto-...

“…Inductors of this gall were obtained after several months of rearing in the laboratory. Adults and immatures of this species were then described by MAIA (1995) as Myrciamyia maricaensis. This gall produced by the M. maricaensis presents two other well defined shapes, distinct from the original one.…”

Myrciamyia maricaensis Maia, 1995 (Diptera, Cecidomyiidae) induces a gall in lateral and apical shoots in the plant Myrcia lundiana Kiaersk (Myrtaceae) which is used and modified by two eulophid wasps species. In both cases the gall former species suffer high rate of attack exceeding the importance of parasitoid species as mortality factors. In this study these interactions are described and their effects as mortality of gall former. The intensity of occurrence of the two eulophid species as modifiers and of microhymenopteran parasitoids, and the relative importance of these species as mortality agents of the M. maricaensis larvae is compared. This comparison reveals that two modifiers species found in the gall tissue modification causing the death of the M. maricaensis larva and it is a more important factor of mortality than the cecidomyiid larva parasitism. The fluctuation of the number of each type of gall along the year was monitored in the research field and confirmed in numerical and in synchronic terms of occurrence of the galls; the importance of the species of the gall modifier eulophids, particularly one of these species, as factors of mortality of the M. maricaensis larvae and justified our comparing the relationship between these species and M. maricaensis as similar to the parasitoid-host relationship. The gall shape modification by one of the eulophids allows the occurrence of other inquiline insect species, what means that this gall modification becomes it more heterogeneous and allows the increase of the species richness to the system

By not having any of the sets of features above, Fernandesia cannot be placed to tribe. Lasiopteridi comprise 59 genera which are also unplaced to tribe, being 21 Neotropical (Gagné 2010). An identification key of tribes Lasiopteridi and a key to segregate the Neotropical genera are provided, as well, to better characterize the new genus. All specimens were first preserved in 96% alcohol and later mounted on slides following the methodology of Gagné (1994). The material (including the types) was incorporated in the Diptera collection of Museu Nacional, Rio de Janeiro, Brazil. The terminology of the adult and immature stages follows Gagné (2009). Material and Methods SamplesField work and gall midge rearing were done by C. R. Wenzel and M. S. Mendonça, Jr. and the descriptions of the new taxa were done by A. R. Rodrigues and V. C. Maia.The key of Lasiopteridi tribes was based on diagnoses of Gagné (2010). The key of unplaced genera of Neotropical Lasiopteridi were done based on original descriptions (Brethes 1917, Felt 1922, Kieffer 1913a, b, Kieffer & Herbst 1909, 1911, Kieffer & Jörgensen 1910, Gagné 1994, Maia 1994, 1995b, 2001, 2005, Rübsaamen 1905, 1916, Tavares 1909) is presented, excepting Angeomyia Kieffer & Herbst 1909, known only from the larva.
