Chrysotus capellarii Soares & Carvalho-Filho sp. nov. is described and illustrated based on a single specimen collected in the department of Córdoba, Colombia, representing the first record of the longipalpus species group from the country (a photographic record is known from Costa Rica). The new species is easily recognized by the long palpus (about 2x longer than eye height) with a wide and oval apical lamella.

The foraging activity of floral visitors is influenced by habitat conditions and abiotic factors. The aim of this research was to define the faunal composition of the visitor community in Solanum lycocarpum A.St.-Hil. (Solanaceae) and to evaluate the influence of abiotic factors on the flight activity of the predominant visitors. The capture of bees was conducted for 15 minutes from the beginning of each hour between 6:00 am and 6:00 pm in a cluster with 15 S. lycocarpum individuals during 10 days. Centridini was the predominant tribe of bees, with 83.5% of the total foraging recorded. About 66.5% of foraging was concentrated in the time interval between 8:00 am and 12:59 pm, characterized as a optimal foraging period. At 6:00 am and from 5:00 pm onwards, bees were discouraged from foraging. Only Epicharis flava Friese and Centris scopipes Friese were classified as predominant species. Centris scopipes was the only predominant species whose abiotic conditions interfered in the foraging activities. Since bee foraging records were developed in the summer, environmental conditions did not limit the foraging of most bees during the entire foraging period of the day.

Species richness of stingless bees (Hymenoptera: Apidae: Meliponini) was organized and updated from previously published data. From this research, we found 28 genera with 259 valid species and 62 undescribed species, in addition, brief comments on the classification used and geographical occurrences were included.

This study was conducted at the Universidade Estadual de Mato Grosso do Sul, Cassilândia, Brazil from September 2017 to December 2021 in a Brazilian Cerrado. Adults of Anomala testaceipennis Blanchard were collected associated with host plants and taken to the laboratory for studies. Some phytophagous scarab beetles found host plants through detection of plant volatiles. The detection of those odorants is intermediated by antennal sensilla. The main goals of the present study are to describe the antennal sensilla of A. testaceipennis and check the host plants used as food resource. This specie was found feeding on flowers of: Anadenanthera colubrina var. cebil (Fabaceae), Azadirachta indica (Meliaceae), Buchenavia sp. (Combretaceae), Cordia glabrata (Boraginaceae), Inga edulis (Fabaceae), Moquilea tomentosa (Chrysobalanaceae), Paubrasilia echinata (Fabaceae), Tabernaemontana catharinensis (Apocynaceae), Tapirira guianensis (Anacardiaceae), Xylophragma pratense (Bignoniaceae). To the sensilla study, antennae were dissected and images of the sensilla were obtained using a scanning electron microscope. Antennae of A. testaceipennis have sensilla chaetica, trichodea, placodea (type I, II, and III), coeloconica (type I and II), basiconica (type I), and ampullacea (or pore). Males have a total of about 6,243 sensilla of which 5,868 (93.99%) are sensilla placodea, 370 (5.93%) are sensilla coeloconica, and 5 (0.08%) are sensilla basiconica. Females have a total of about 5,119 sensilla of which 4,820 (94.16%) are sensilla placodea, 270 (5.27%) are sensilla coeloconica, and 29 (0.57%) are sensilla basiconica.

Galls are small structures induced mostly by insects in different plant organs, and have different shapes and colorations. Knowledge on galls is still sparse in the semiarid region of Bahia. Therefore, the goal of this study was to characterize galls in fragments of seasonal deciduous forest. Sampling was performed in the Bahia municipalities of Boa Nova, Jequié, Poções and Vitória da Conquista. In each site, one fragment was chosen, and in each fragment, plots were established to survey galls on vegetation. We sampled 158 gall morphotypes, representing 49 (morpho) species distributed across 15 families of host plants. Myrtaceae and Malphigiaceae had the highest numbers of gall morphotypes. Most galls were collected from leaves, whereas the most common gall morphotypes were globoid and fusiform.

Lonomia Walker, 1855 is a genus of Lepidoptera belonging to the Saturniidae whose caterpillars have a defense system based on scoli connected to venom glands, which can cause medical accidents of envenomation, thereby making this genus medically important. In this work, Lonomia camox Lemaire, 1971, is recorded for the first time in Brazil, more specifically in the state of Amazonas. Photographs of male and female genitalia and an updated map with new occurrence records are presented.

Prosierola is characterized by having a pair of conspicuous anteromedial metapostnotal foveae on the metapectal-propodeal disc. Little is known about this genus because it is rarely sampled in collections. Therefore, the main goal of this contribution is to expand the knowledge of intraspecific morphological variations and geographical distribution of its species that occur in Brazil. We sorted material from the main collections and obtained 69 specimens of Prosierola nasalis (Westwood) recorded for the first time from Maranhão, Minas Gerais, Pará, Rio Grande do Norte and Rio Grande do Sul; one of Prosierola obliqua Evans recorded for the first time from Distrito Federal; five of Prosierola rotunda Schiffler & Azevedo recorded for the first time from Pará; and 13 of Prosierola rufescens Evans recorded for the first time from Brazil (Amazonas, Bahia, Espírito Santo, Minas Gerais). The mesoscuto-scutellar foveae placed on the dorsal surface of the mesoscutellum shown to be highly variable in size, distance, and shape at both the intra- and interspecific levels.

Delia Robineau-Desvoidy, composed of flies popularly known as root maggot flies, is a diverse genus with unclear delimitation. It comprises polyphagous species and some important agricultural pests. Delia sanctijacobi (Bigot) is native to South America, occurring in Argentina, Brazil, Chile, Peru, and Uruguay; the larvae are commonly known as “potato worms” and have been misidentified as Delia platura (Meigen) in Brazil. Delia sanctijacobi attacks the seeds and seedlings of several plants of commercial importance. We present new geographic records of D. sanctijacobi in Brazil and describe the damage caused by their larvae on commercial bean and onion in Paraná and Santa Catarina between 2019-2022.

Inventories provide important information about species, both from a biogeographic perspective and in terms of their conservation status. Among insects, dragonflies are extensively surveyed in Brazil; however, significant knowledge gaps still exist regarding the distribution of these organisms in the country, particularly in threatened biomes such as the Atlantic Forest. In this study, we present data on an Odonata community collected in the Serra do Papagaio State Park between 2015 and 2016. We recorded 64 species, including six new records for the state of Minas Gerais, along with ten species with problematic conservation status, either due to a lack of distribution data or some degree of extinction risk. Our results highlight the importance of inventories in expanding our knowledge of species distribution and providing data that can aid in the assessment of their conservation status.
