Phytoseiid mites (Acari: Phytoseiidae) have been largely used for the biological control of arthropod pests. However, information on the phytoseiid fauna associated with plants of the Rio de Janeiro State, Brazil is still scanty. Surveys were carried out in two areas of Atlantic Forest in Rio de Janeiro State – Jaguanum island and Paraty. We report 11 species of seven genera from all three subfamilies. A complementary re-description is provided for Amblyseius impeltatus Denmark & Muma, 1973 and measurements are provided for ten other species.

A new gall midge genus, Distinctamyia gen. nov., and a new species Distinctamyia matogrossensis sp. nov. (Diptera, Cecidomyiidae) are herein described and illustrated (larvae, pupal exuviae, male and female). The new species induces conical, green, hairy and one chambered galls on leaf and bud of Simarouba amara Aubl. (Simaroubaceae). Gall-inducer specimens, samples of gall and host plant were collected at Parque Nacional da Chapada dos Guimarães, in the state of Mato Grosso (Midwestern Brazil).

Specimens of the hydromedusa Cnidocodon leopoldi Bouillon, 1978 were collected in waters off the northeast Brazilian coast between 7.4°S, 34.3°W and 8.7°S, 34.8°W. The genus can be distinguished from other anthomedusae by the presence of four marginal perradial bulbs having an adaxial nematocyst cushion and branched capitate tentacles, an umbrella with scattered nematocysts, and gonads around a cylindrical manubrium shorter than the umbrella. Specimens were assigned to C. leopoldi due the tentacles with 4-5 branches and the absence of ocelli on tentacle bulbs differing from the congeneric Cnidocodon ocellata Huang, Xu, Lin & Qiu, 2008. This study represents the first record of the species in the Atlantic Ocean.

The new genus Stapafurdius gen. nov. is introduced collected from Bahia, Brazil, including two new species: S. glaber sp. nov., the type species, occurs in Ibicoara; and S. costiferus sp. nov., from Andaraí regions. The new genus includes species of about 10 mm, elongated shell, reticulated protoconch, elongated peristome, and wide umbilicus. Both species differ mainly by the sculpture, as S. glaber sp. nov. is smooth, while S. costiferus sp. nov. has strong axial sculpture. urn:lsid:zoobank.org:pub:C851695E-6BF1-4418-8D8A-8BC7D10CC2FE.

Frugivory is a plant-animal mutualistic interaction carried out mostly by birds. It consists in the bird consumption of fruits with later dispersion of the plants' seeds, helping in the vegetation regeneration. Frugivory can be affected by the habitat fragmentation and introduction of exotic species, which may alter the species interaction by extinction or competitor introduction. This study aimed to compare the structure of the network of frugivorous interactions between birds and plants in native forest and eucalyptus plantation. Birds were captured by mist nets and had their feces collected. Later, the seeds were identified in laboratory. The records of fruit consumption by birds in the zoochoric plant species present in the study area were also conducted. The data collected was used to build a network of interactions and identify the most important network metrics, species, and ecological functional groups in the studied environments. The results showed that the species composition, the connectivity of the relationships, the importance of the species for the interaction networks and the number of subgroups within the networks were highly similar between the native forest and the eucalyptus plantation. This could be explained by the favorable conditions that the studied eucalyptus plantations presented, such as the lack of anthropogenic activities, well-developed understory, and the presence of native surrounding vegetation, allowing practically the same seed dispersal capacity in both types of environments.

The morphology of Clessidromma palmeri Jarzembowski et al. from mid-Cretaceous Burmese amber is revised based on a reexamination of the type specimen. Contrary to previous studies, our observation confirms that Clessidromma has open procoxal cavities. The characters such as platform on the ventral side of head, modified metacoxae, and ridges on head and pronotum are suggested to be diagnostic characters for Clessidromma. Clessidromma zengi Kirejtshuk from the same deposit is transferred into a new genus, as Kirejtomma zengi comb. nov.

The monotypic genus Bunostigma Mello-Leitão, 1935 is herein revisited. A detailed redescription of its type-species, Bunostigma singulare Mello-Leitão, 1935 from Rio de Janeiro state, eastern Brazil, is herein presented, providing in depth knowledge of this genus. Bunostigma is most closely related to Cryptogeobius Mello-Leitão, 1935, and as this genus, it has a stout complex apophysis on male coxa IV, lacking, however, a second complex on the stigmatic area. Bunostigma has an oblique elongate malleus, similar to that of Zalanodius Mello-Leitão, 1936 (as opposed to a globular malleus in Cryptogeobius). Bunostigma singulare has short legs, with some sexual dimorphism on its stoutness, a dorsal scutum entirely unarmed and an ocularium with an accessory central mound, although unarmed.

The present study provides historical and new records of the introduced millipedes species in Brazil, Oxidus gracilis (C.L. Koch, 1847), Orthomorpha coarctata (Saussure, 1860) (Paradoxosomatidae), Prosopodesmus jacobsoni Silvestri, 1910 (Haplodesmidae), Trachyjulus calvus (Pocock, 1893a), Glyphiulus granulatus (Gervais, 1847) (Cambalopsidae), Trigoniulus corallinus (Gervais, 1842), Leptogoniulus sorornus (Butler, 1876), Epitrigoniulus cruentatus (Brölemann, 1903) (Pachybolidae), Paraspirobolus lucifugus (Gervais, 1837) (Spirobolellidae), Cylindroiulus britannicus (Verhoeff, 1891), Cylindroiulus truncorum (Silvestri, 1896) (Julidae), and Rhinotus purpureus (Pocock, 1894) (Siphonotidae). Among the 27 federative units in Brazil, 21 states present at least one record of a non-native species. Orthomorpha coarctata was the most widely distributed species, occurring in 15 states. Glyphiulus granulatus (state of Rio Grande do Sul), C. truncorum (São Paulo), and R. purpureus (Amazonas) were recorded from only one Brazilian state. The Southeast region concentrates most of the compiled records (42,6%) and richness by grid (5-7 species), mainly in urban areas of the states of Rio de Janeiro and São Paulo.

A new species of the Afro-Palearctic genus Pandelleia Villeneuve, 1907 (Diptera: Tachinidae), P. crosskeyi sp. nov., from Mauritius is described. This is the first Dexiinae to be described from Mauritius. In addition, this new species corresponds to the ninth species for this genus, and the third in the Afrotropics. The main external features that distinguish it from the other species in this genus is the abdomen that lacks the pair of small, round and dark brown spots, vein M ending in R₄₊₅ at a 90° angle, and female with dark brown scutellum.

The recent edition of the Red Book of Endangered Brazilian Fauna brings 1,173 threatened species, 86% of them in terrestrial or freshwater environments. For these species, the main threat vector is agricultural activities that affect 519 species (51%). This information brought by the Red Book is examined in-depth and its consistency is discussed in search of an objective view on the impacts of agriculture, its importance, how they affect the different groups of animals, the different biomes of the country, and the different types of habitats continental. Birds, fish, and invertebrates are the groups with the highest number of species threatened by agricultural activity, accounting for more than 70% of the species. Habitat loss is by far the biggest impact caused by the activity, affecting almost 90% of the species. However, there is a difference between the impact of agriculture and livestock. The work seeks to understand why livestock threatens a smaller number of species, although pastures occupy more than twice the area occupied by crops and forestry. The work brings an objective debate on the relationship between agricultural activities and the conservation of wild fauna in Brazil, without falling into the trap of the useless demonization of human activities, highlighting, instead, the need to define and implement strategies for the conservation of biodiversity in the midst the land use matrix itself, complementary to the conservation units, based on the best available information on the vulnerability of fauna to the impacts of this vector.
