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 family Lycaenidae (Lepidoptera) comprises over 6,000 described and widely distributed species. However, studies on interactions with other insects such as ants, parasitoids, and with food plants in the Neotropical region, are still scarce, even though such information are fundamental for better understanding the natural history of this taxonomic group. This study reports a new food plant to larvae of Lycaenidae species in the neotropics, as well as its parasitoid. A Lycaenidae larva was found and collected for immature stage observation under laboratory conditions. The larva fed on petals and seeds of Zornia latifolia Sm. (Fabaceae). Nineteen days after pupation in laboratory a larvipupal parasitoid of the genus Conura (Chalcididae) had egressed. This is the first report of tritrophic relationship amongst Z. latifolia, a Lycaenidae larva and its larvipupal parasitoid of the genus Conura in a periurban area near remnants of the Atlantic Forest, in Northeastern Brazil.

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.

Although Pantophthalmidae are widespread in the Neotropical Region, only three of 20 species of the family are known in the Northeast region of Brazil: Pantophthalmus planiventris (Wiedemann, 1821), Pantophthalmus tabaninus Thunberg, 1819, and Pantophthalmus vittatus (Wiedemann, 1828). In this paper, we record, for the first time, Pantophthalmus comptus Enderlein, 1912 from the state of Maranhão, in area of state covered by Amazon Forest biome, and Pantophthalmus pictus (Wiedemann, 1821) from the state of Pernambuco, near the coast, within the Atlantic Forest biome. These two species have been reported elsewhere from Brazil and now their distribution has expanded to the Northeast. Also, we provide images of a female specimen of P. planiventris, known, in the Northeast region of Brazil, from the state of Maranhão only, and of the male terminalia of P. comptus. This paper increases the number of known species of Pantophthalmidae from the Northeast Brazil to five species.

In this paper, the range of occurrence of Thambemyia fusariae Capellari, 2015 is expanded to south and southeastern Brazil, with the first records for the states of São Paulo and Santa Catarina. These now represent the southernmost records of the species, which has been known only from its type locality in Uruçura, state of Bahia, Brazil. In addition, we provide a distribution map and additional photographs of the species.

The aim of this work was to assess the diversity of Hymenoptera in an orange orchard / Brazilian savannah fragment interface in Descalvado, State of São Paulo, Brazil, using Moericke, Malaise and pitfall traps. The sampling was carried out from February to June 2006, when 5,148 specimens of Hymenoptera, from 12 superfamilies and 36 families, were caught: Chalcidoidea (1,885 specimens; 36.6% out of the total; 14 families), Ichneumonoidea (715; 13.9%; 2), Vespoidea (554; 10.8%; 5), Apoidea (444; 8.6%; 2), Diaprioidea (430; 8.4%; 2), Chrysidoidea (366; 7.1%; 3), Platygastroidea (340; 6.6%; 2), Ceraphronoidea (211; 4.1%; 2), Cynipoidea (107; 2.1%; 1), Evanioidea (83; 1.6%; 1), Tenthredinoidea (7; 0.1%; 1) and Trigonaloidea (6; 0.1%; 1). The Moericke and Malaise traps installed in the Brazilian savannah fragment were responsible for capturing the highest number of Hymenoptera (2,158 specimens; 41.9% out of the total collected and 1,739; 33.8%, respectively), followed by the Moericke traps placed in the orange orchard (1,123; 21.8%) and by the pitfall traps (128; 2.5%). The results indicate that the diversity of families of Hymenoptera in the Brazilian savannah fragment is greater than in the culture of citrus and expresses the greatest diversity of hosts existing in that environment. The study made clear that the combined use of different kinds of traps allows the capture of a large diversity of Hymenoptera. Amostragem e Diversidade de Hymenoptera (Insecta) em uma Interface Cultura de Citros/Fragmento de Cerrado Resumo. O objetivo deste estudo foi avaliar a diversidade de himenópteros de uma interface cultura de citros/fragmento de Cerrado em Descalvado, SP, Brasil, através do uso de armadilhas de Moericke, de Malaise e de pitfall. As amostragens ocorreram entre fevereiro e junho de 2006, quando foram obtidos 5.148 exemplares de himenópteros pertencentes a 12 superfamílias e 36 famílias: Chalcidoidea (1.885 exemplares; 36,6% do total; 14 famílias), Ichneumonoidea (715; 13,9%; 2), Vespoidea (554; 10,8%; 5), Apoidea (444; 8,6%; 2), Diaprioidea (430; 8,4%; 2), Chrysidoidea (366; 7,1%; 3), Platygastroidea (340; 6,6%; 2), Ceraphronoidea (211; 4,1%; 2), Cynipoidea (107; 2,1%; 1), Evanioidea (83; 1,6%; 1), Tenthredinoidea (7; 0,1%; 1) e Trigonaloidea (6; 0,1%; 1). As armadilhas de Moericke e de Malaise instaladas no fragmento de Cerrado capturaram o maior número de exemplares de himenópteros (2.158 exemplares; 41,9% do total coletado e 1.739; 33,8%, respectivamente), seguidas pelas de Moericke instaladas na cultura de citros (1.123; 21,8%) e pitfall (128; 2,5%). Os resultados obtidos indicam que a diversidade de famílias de himenópteros no fragmento de Cerrado é maior do que na cultura de citros e expressa a maior diversidade de hospedeiros existente naquele ambiente. O uso combinado de diferentes tipos de armadilhas possibilitou a captura de maior diversidade de grupos de himenópteros.
