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.

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.

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.

A Coleção Costa Lima do Instituto Oswaldo Cruz não recebe material novo para depósito, mas é extremamente diversificada e historicamente importante. Ela reúne um total de sessenta e seis holótipos, setenta e nove parátipos e nove síntipos da subordem Heteroptera, representando as famílias Cimicidae, Miridae, Polyctenidae, Reduviidae e Tingidae. Este relevante material é aqui compilado e apresentado pela primeira vez.List of the Type-Specimens of Heteroptera (Insecta: Hemiptera) in the Costa Lima Collection, Oswaldo Cruz Institute, Rio de Janeiro, BrazilAbstract. The Costa Lima Collection of the Oswaldo Cruz Institute does not receive new material to be deposited, but is extremely diversified and historically important. It gathers a total of sixty-six holotypes, seventy-nine paratypes and nine syntypes of the suborder Heteroptera, representing the families Cimicidae, Miridae, Polyctenidae, Reduviidae, and Tingidae. This relevant material is herein compiled and presented for the first time.

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.

Abstract. This scientific note refers to the first record of a larvae of mite of genus Leptus (Acari: Erythraeidae) found parasitizing a specimen of horsefly (Diptera: Tabanidae) on Marambaia Island, Mangaratiba, Rio de Janeiro, Brazil.Primeiro registro de Leptus sp. (Latreille) (Acari: Erythraeidae) parasitando mutuca (Diptera: Tabanidae) da Ilha da Marambaia, Mangaratiba, Rio de Janeiro, BrasilResumo.

Abstract. Here, by the first time, was quantified the predation of seeds of Protium ovatum Engl. (Burseraceae) by Bracon zuleideae Perioto & Lara (Hymenoptera, Braconidae), a phytophagous seed eater, in Parque Nacional Grande Sertão Veredas, located in the State of Minas Gerais, Brazil. B. zuleideae is now mentioned for the state of Minas Gerais, Brazil, which extends its geographical distribution about 900 km north of its type locality, its only previous record, and new data about host plant phenology are provided.Bracon zuleideae Perioto & Lara (Hymenoptera, Braconidae): potencial de predação de sementes, expansão da distribuição geográfica e novos dados de fenologia da planta hospedeiraResumo. A predação de sementes de Protium ovatum Engl. (Burseraceae) por Bracon zuleideae Perioto & Lara (Hymenoptera, Braconidae) foi quantificada pela primeira vez no Parque Nacional Grande Sertão Veredas, em Minas Gerais, Brasil. A distribuição geográfica de B. zuleideae é estendida para o Estado de Minas Gerais, Brasil, a cerca de 900 km ao norte da localidade tipo, o único registro anterior, e novos dados sobre a fenologia da planta hospedeira são fornecidos.

Abstract. Ophionyssus natricis (Gervais) frequently parasitizes snakes kept under human care. This mite is known to mechanically transmit the bacteria Proteus hydrophilus, which can cause hemorrhagic sepsis in snakes. This is the first record of O. natricis mite in Python reticulatus (Schneider) collected in captivity, in Brazil. The micrographs and drawings generated in this study, based on optical light microscopy and SEM observations, highlight an important identifying characteristic of O. natricis: The dorsal surface has two shields, consisting of propodosomal and pygidial, and the ventral surface has only the sternal shield trapezoidal with two pairs of setae, and pores on the edge. The identification of adults female of O. natricis mites in P. reticulatus collected in wild animals kept under human care, in Brazil, provides additional anatomical information to help identify the species by providing more necessary information to understand the morphology of snake mites.Primeiro registro de Ophionyssus natricis (Gervais) (Acari: Macronyssidae) em Python reticulatus (Schneider) (Pythonidae) no BrasilResumo. Ophionyssus natricis (Gervais) frequentemente parasita cobras mantidas sob cuidados humanos. Este ácaro é conhecido por transmitir mecanicamente a bactéria Proteus hydrophilus, que pode causar sepse hemorrágica em cobras. Este é o primeiro registro O. natricis em Python reticulatus (Schneider) coletados em cativeiro, no Brasil. O estudo foi realizado com o auxílio de microscopia óptica e observações de MEV, gerando desenhos e micrografias, o que permitiu observar importantes características de identificação da fêmea de O. natricis: superfície dorsal com dois escudos, consistindo em propodossoma e pigidial, já a superfície ventral possui apenas o escudo esternal com forma trapezoidal, com dois pares de cerdas e poros na borda. A identificação das fêmeas adultas de O. natricis coletados em P. reticulatus mantidas sob cuidados humanos no Brasil, fornece informações anatômicas adicionais para ajudar na identificação da espécie fornecendo mais informações necessárias na compreensão da morfologia dos ácaros das cobras.
