Insect galls from the Botanical Garden of the Museu Nacional (Rio de Janeiro, RJ, Brazil).

The Botanical Garden of the Museu Nacional/Universidade Federal do Rio de Janeiro (Rio de Janeiro, RJ, Brazil) was investigated monthly from October, 2017 to December, 2019 in a total of 27 collections, each lasting four hours, following the methodology of random walking. Vegetative and reproductive organs of herbs, bushes and trees (up to 2 m high) were examined by two people. Voucher material was deposited in the Entomological Collection of the Museu Nacional (MNRJ)/Universidade Federal do Rio de Janeiro. We found 13 insect gall morphotypes in nine host plant species of four families. All host plants are native of Brazil, except Ficus microcarpa L.f. (Moraceae), which is naturalized. Myrtaceae and Moraceae were the plant families with the greatest richness of gall morphotypes. Eugenia L. (Myrtaceae) and Ficus L. (Moraceae) were the plant genera with the highest number of gall morphotypes. In several inventories in the Atlantic forest, Myrtaceae and Eugenia stand out for harboring a great variety of galls, while Moraceae and Ficus were never stood out for this reason. Most plant species mentioned in the present study were already known as hosts of gall-inducing insects in Brazil. However, for the first time, insect galls are reported on Ficus crocata (Miq.) Miq. (Moraceae). We found two new morphotypes on Eugenia florida DC. (Myrtaceae). Leaves, stems and buds were the galled organs. Cecidomyiidae were the most frequent inducers. Galls of Thysanoptera were also found. Inquilines were observed in leaf galls on Eugenia florida. They promoted differences in gall morphology and killed the gall-inducing larva.

Review of the inquilinous fauna associated with insect galls in Brazilian restingas / Revisão da fauna inquilina associada a galhas de insetos em restingas brasileiras

Several records of associated fauna, including parasitoids, inquilines, predators, and successors, have been reported by insect gall inventories in Brazilian restingas. Although most guilds are well established, inquilines have frequently been misinterpreted. In this paper, the inquilinous fauna of insect galls is revised based on five criteria: food habit; coexistence with the inducer; modification of gall tissues or production of new tissues; phylogenetic relationship with the inducer; and mobility. Gall inventories dated from 1988 to 2019 were examined, totaling 16 publications, eight of them with inquiline records. This guild was reported in 53 gall morphotypes in 44 plant species and four morphospecies distributed among 36 genera of 24 host families for a total of 65 records. Most inquilines were repositioned into the cecidophage guild and others into the kleptoparasite guild, resulting in a large reduction in the frequency of inquilines (from 65 to five records), and in first reports of cecidophages and kleptoparasites, with 46 and 13 records, respectively. Cecidophage was the most diverse guild with insects of five orders (Diptera, Coleoptera, Lepidoptera, Hemiptera, and Thysanoptera) while kleptoparasites were represented only by two orders (Diptera and Hymenoptera) and inquiline solely by Hymenoptera. Other results indicate that Leptothorax sp. (Formicidae) could be a successor and not an inquiline.

Nesse trabalho, a fauna inquilina de galhas de insetos é revisada com base em cinco critérios: hábito alimentar, coexistência com o indutor, modificação dos tecidos da galha ou produção de novos tecidos, relação filogenética com o indutor e mobilidade. Inventários de galhas publicados entre 1988 e 2019 foram examinados, totalizando 16 artigos, oito deles com registro de inquilinos. Essa guilda foi assinalada em 53 morfotipos de galhas em 44 espécies de plantas e quatro morfoespécies distribuídas em 36 gêneros de 24 famílias vegetais, totalizando 65 registros. A maioria dos inquilinos foi reposicionada na guilda dos cecidófagos e outros na guilda dos cleptoparasitas, resultando em uma grande redução da frequência dos inquilinos (de 65 para cinco registros), e na primeira ocorrência de cecidófagos e cleptoparasitas, com 46 e 13 registros, respectivamente. A guilda dos cecidófagos foi a mais diversa, com insetos de cinco ordens (Diptera, Coleoptera, Lepidoptera, Hemiptera e Thysanoptera), enquanto que os cleptoparasitas foram representados por apenas duas ordens (Diptera e Hymenoptera) e os inquilinos somente por Hymenoptera. Outros resultados indicam que Leptothorax sp. (Formicidae) pode ser um sucessor e não um inquilino.

Diversity of Calliphoridae and Mesembrinellidae (Diptera: Oestroidea) in a Mangrove, Restinga, and Forest Landscapes From a Lagoon Complex on an Atlantic Forest Coastline (Rio de Janeiro, Brazil).

Diptera Mesembrinellidae present great ecological importance as potential bioindicators and Calliphoridae stand out for their medical-sanitary importance as potential vectors of pathogens and causes of human and animal diseases such as myiasis. They beneficially aid in elucidating crimes in forensic entomology, contributing to determine the postmortem interval (PMI) and assisting in the healing process of necrotic wounds in larval therapy. This study aimed to inventory the Calliphoridae and Mesembrinellidae fauna in order to evaluate structural parameters and to apply faunal indexes in catching species in the Itaipu-Piratininga lagoon complex, in Niterói (Rio de Janeiro), Brazil. The collections were carried out monthly from September 2015 to August 2016 with fish bait (sardines) exposed for 48 h, totaling six traps installed in three physiognomies (mangrove, ombrophilous forest, and restinga). In total, 9,773 individuals were captured, divided into two families, five genera, and 11 species. Chrysomya megacephala (Fabricius, 1794) was the predominant species, while Mesembrinella bellardiana (Aldrich, 1922) was the least representative species, indicating the preservation level of this ecosystem. Ombrophilous forest was the physiognomy with greater diversity and restinga was the physiognomy with greater species dominance. The similarity index indicated greater similarity among the mangrove and restinga populations.

Myrciamyia pterandrae (Diptera, Cecidomyiidae, Lopesiini), a new species of gall midge associated with Pterandra pyroidea A. Juss. (Malpighiaceae), an endemic plant in Brazilian Cerrado

ABSTRACT Myrciamyia pterandrae (Diptera, Cecidomyiidae), a new galling species associated with Pterandra pyroidea (Fabaceae), an endemic plant species in Brazilian Cerrado, is described based on larva, pupa, male and female. M. pterandrae galls were collected in the municipality of Quartel de São João, State of Minas Gerais, southeastern Brazil. Larvae were removed from the galls and pupae, and adults were obtained by rearing. The specimens were mounted on slides, and the diagnostic morphological characters were illustrated. M. pterandrae is compared to Myrciamyia maricaensis Maia, 1996 the unique, previously known species of the genus.

Phylogeny of the genus Stephomyia Tavares, 1916 (Diptera: Cecidomyiidae) / Filogenia do gênero Stephomyia Tavares, 1916 (Diptera: Cecidomyiidae)

Abstract 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)))).

Resumo Stephomyia Tavares, 1916 compreende sete espécies, todas neotropicais: S. clavata (Tavares, 1920); S. epeugeniae Gagné, 1994; S. espiralis Maia, 1993; S. mina Maia, 1993; S. rotundifoliorum Maia, 1993; S. tetralobae Maia, 1993 e S. eugeniae (Felt, 1913). Neste estudo, uma análise cladística baseada em caracteres morfológicos dos adultos, pupa, larva e galha, bem como na informação das plantas hospedeiras é realizada e a monofilia do gênero e as relações entre as espécies conhecidas são discutidas. A monofilia de Stephomyia foi suportada por oito sinapomorfias: cinco caracteres homoplásticos e três não homoplásticos. Análises mostraram uma grande instabilidade de S. clavata dentro do gênero, provavelmente devido à falta de informações sobre a larva, a pupa e a fêmea, o que resultou em desativação na análise. A topologia encontrada foi (S. mina ((S. eugeniae + S. epeugeniae) (S. tetralobae (S. rotundifoliorum + S. espiralis)))).

The insect gall collection of the Museu Nacional/Universidade Federal do Rio de Janeiro: biome cerrado, rupestrian fields.

An inventory of the insect gall from Brazilian savanna (Cerrado) was elaborated based on samples of the collection of the Museu Nacional, Universidade Federal do Rio de Janeiro. Data on localities and host plants were obtained from the labels and information about the gall morphology (plant organ of occurrence, shape, and presence of trichomes) by observing the samples. The galling species was determined based on the literature. The collection includes 131 morphotypes of galls from Cerrado, obtained from 71 host plant species distributed in 50 genera and 30 botanical families (Table 1). All galls were collected in rupestrian fields (a rare vegetation physiognomy of the Brazilian Cerrado) in the state of Minas Gerais. As the collection comprises a great diversity of insect galls, it can be considered representative of this physiognomy.
