“…According to Isaias et al (2013), the high frequency of these shapes is related to the patterns of cell growth and differentiation of these plant organs. Most galls were glabrous, as in all other Brazilian inventories (Maia & Mascarenhas 2017). According to Inbar et al 2010, trichomes can act as structural defenses against loss of water or against predators and parasitoids, as they impair their feeding and mobility.…”

“…One hundred and fifty-three gall morphotypes were found in REBIO União. Only two previous Brazilian inventories have been performed in areas of Ombrophilous Forest, the first in Santa Teresa, Espírito Santo , and the second in Parque Nacional de Itatiaia (PNI), Southeast Brazil (Maia & Mascarenhas 2017). The authors recorded 265 and 406 gall morphotypes in these areas, respectively.…”

“…Thus, all galling insect orders were represented at REBIO União with the exception of Coleoptera. Maia et al 2014 andMascarenhas 2017 found galls induced by other insect taxa in their inventories of Ombrophilous Forest, such as Tephritidae (Diptera) and Coleoptera. Cecidomyiidae were the most frequent gallers at REBIO União, following a global pattern.…”

“…Only two gall inventories have been developed in protected areas of Dense Ombrophilous Forest in Brazil, one in Santa Teresa, state of Espírito Santo and the other in the Parque Nacional do Itatiaia (PNI), Southeast Brazil (Maia & Mascarenhas 2017). Other data can be found in various publications (Tavares 1915, 1916, 1917a, 1917b, 1918, 1920a, 1920b, 1922, Kieffer 1913, Gagné 1998, 2001.…”

Several inventories of insect galls have been performed in the Atlantic Forest of Rio de Janeiro, mostly in restingas, whereas the other phytophysiognomies remain poorly sampled. The present study inventoried the insect galls of Reserva Biológica União (RJ), a protected area comprising mainly Ombrophilous Forest. Field work was performed every two months from January to October, 2013. Insect galls were collected, photographed, characterized and transported to the laboratory. Adults were obtained by rearing and immature stages by gall dissection. The insects were deposited in the Cecidomyiidae Collection of the Museu Nacional. A total of 153 gall morphotypes were found on plants representing 37 plant families, 69 genera, 55 species and 53 morphospecies. Among them, two plant genera and five species were reported for the first time as host plants in Ombrophilous Forest. REBIO União showed little similarlity of host plant species and insect gall morphotypes when compared with other investigated Ombrophilous Forest areas. The leaf was the most attacked plant organ as expected. Asteraceae, Bignoniaceae, Fabaceae and Myrtaceae, and Mikania (Asteraceae) and Myrcia (Myrtaceae) were the richest host families and genera, respectivey, in number of gall morphotypes, all previously indicated as superhosts by other Brazilian Ombrophilous Forest inventories, except Bignoniaceae. Their great species richness may be related to their great gall richness, adding evidence in support of the taxon size hypothesis. Fusiform and globose galls were the most frequent, green was the predominant color, and most morphotypes did not present an indumentum. The highest gall richness was recorded in June and August. The gallers were distributed among Diptera (Cecidomyiidae), Lepidoptera, Hymenoptera, Hemiptera and Thysanoptera, with the first being predominant, following a global pattern. Eight gall-inducing species are recorded for the first time in REBIO União and four in Ombrophilous Forest. About 25% of the gall morphotypes were occupied by dwellers other than those that created the gall. They comprised parasitoids (Hymenoptera), inquilines (Diptera: Sciaridae and Muscomorpha, Hemiptera, and Lepidoptera) and successors (Psocoptera, mites, and Hymenoptera: Formicidae). Although these taxa were previously reported by Brazilian inventories of insect galls, 12 new association with plants are recorded. The amount of new records reinforces the importance of inventories.Resumo: Vários inventários de galhas de insetos vem sendo desenvolvidos no estado do Rio de Janeiro, principalmente em restingas, enquanto as outras fitofisionomias permanecem pouco estudadas.

“…In none of these the inducer was identified at a specific level, one gall was mite-induced (Eriophyidae) and five by the orders Diptera, Hemiptera and Thysanoptera. In Niphidium crassifolium, Houard (1933) found that the inducer is a Coccidae (Hemiptera); Maia & Mascarenhas (2017) also recorded globoid gall morphotype on the adaxial side of the leaves of this fern (Figues. 1 E-F).…”

Galls are neo-formed plant structures induced by species-specific interaction between an inducing organism and a host plant. Lycophytes and ferns are two distinct plant lineages historically lumped together as pteridophytes. A number of authors suggest low gall frequency in lycophytes and ferns, compared to angiosperms. This study aimed at compiling an updated overview of fern galls in Brazil, providing information on hosts, gall-inducing organisms and associated fauna. The synopsis was compiled using existent data and by updating scientific names and gathering new information obtained by the authors in fieldwork. To date, galls have been recorded on 16 fern species but none on lycophytes. However, the inducer was identified at species level in only three gall morphotypes from three fern species, with a doubtful inducer for Pteridium sp. Galls are induced by mites (Eriophyidae) and insects of the orders Diptera, Lepidoptera, Thysanoptera, and Hemiptera, Cecidomyiidae (Diptera) being the most frequent galler insect. Keywords: Pteridophytes, lycophytes, galls, Neotropical, Cecidomyiidae. Sinopse de galhas em samambaias no BrasilResumo: Galhas são estruturas vegetais neoformadas induzidas por interações espécie-específicas entre um organismo indutor e uma planta hospedeira. Licófitas e samambaias são duas linhagens de plantas historicamente classificadas juntas como pteridófitas. Diversos autores sugerem que há uma baixa frequência de galhas em licófitas e samambaias, em comparação com as angiospermas. Este trabalho tem como objetivo fornecer um panorama atualizado sobre as galhas em samambaias no Brasil, disponibilizando informações sobre espécies hospedeiras, galhadores e fauna associada. A sinopse foi realizada compilando-se os dados existentes, atualizando os nomes científicos e agregando informações novas obtidas pelos autores em trabalhos de campo. Até o momento, foram registradas galhas em 16 espécies de samambaias e nenhum registro em licófitas. Contudo, em apenas três morfotipos de galhas, de três espécies de samambaias, o indutor foi identificado a nível de espécie, com um indutor duvidoso para Pteridium sp. As galhas são induzidas por ácaros (Eriophyidae) e insetos das ordens: Diptera, Lepidoptera, Thysanoptera, Hemiptera, sendo Cecidomyiidae (Diptera) o galhador mais frequente.
