Se aportan las primeras observaciones confirmadas de Daphnis nerii (Linnaeus, 1758) en Galicia (España) después de casi 150 años sin haberse observado la especie y se pone de relevancia la importancia de las plataformas de ciencia ciudadana para detectar especies escasas.

Psychotrosia Becker, gen. nov. [Type-species: Trosia zernyi Hopp, 1930], and three new species are described: Microrape clenchi Becker, sp. nov.; M. melanica Becker, sp. nov., and P. venata Becker, sp. nov., are proposed for a group Neotropical Trosiinae.

Three new species from the Philippines are described: Nippoptilia jakobi Ustjuzhanin & Kovtunovich sp. nov.; Hellinsia zurilinae Ustjuzhanin & Kovtunovich sp. nov.; Pterophorus aurora Ustjuzhanin & Kovtunovich sp. nov. One species, Asiaephorus sythoffi (Snellen, 1903), is recorded from the Philippines for the first time.

The Gelechiidae subfamilies Dichomeridinae, Anomologinae and Thiotrichinae in the Canary Islands are revised. We recognize seven species of Dichomeridinae, five species of Anomologinae and two species of Thiotrichinae. Four species are described as new: Dichomeris vivesi Falck & Karsholt, sp. nov., Helcystogramma brachmiaella Falck & Karsholt, sp. nov., Pseudosophronia confluella Falck & Karsholt, sp. nov., and Chrysoesthia diurnella Falck & Karsholt, sp. nov. A lectotype of Nothris castellana Schmidt, 1941, now Dichomeris castellana (Schmidt, 1941), is designated. Dichomeris castellana (Schmidt, 1941), Sitotroga psacasta Meyrick, 1908, and Polyhymno dumonti (Hartig, 1936) are recorded as new to the Canary Islands. We also present several records of species new to single Canary Islands. Dichomeris cisti (Staudinger, 1859) is removed from the list of Lepidoptera in the Canary Islands. The paper is illustrated with photographs of adults and genitalia of the new species as well as of other species when relevant. Analyses of DNA barcodes show that the identifications and distinctiveness of each species as well-supported and genetically isolated.

A survey conducted in Uttarey village, located in the western district of Sikkim, India, has revealed important findings regarding the larval host plants of the Pieris brassicae nepalensis Gray, 1846. This study is particularly noteworthy as it implicates Matthiola incana (L.) W. T. Aiton from the Brassicaceae family and Spinacia oleracea (L.) from the family Chenopodiaceae as new larval host plants for this species. This discovery is the first report of these plants serving as host plants for Pieris brassicae nepalensis Gray, 1846 in India. It adds valuable knowledge to the ecology of the Papilionoidea and expands the known range of larval food sources for this species.

In our study, we examined the volatile androconial scent chemistry of Atlides polybe (Linnaeus, 1763), a Lycaenidae species known for its distinctive “grape-like” aroma. This is the first Theclinae species to have its androconial secretions chemically investigated. Analysis of solvent sample using gas chromatographymass spectrometry revealed 13 ion peaks corresponding to distinct volatile compounds. Among these, methyl anthranilate emerged as the dominant compound, primarily associated with the aldehydes heptanal, octanal, and (E)-2-decenal. This study marks the first report of methyl anthranilate as a volatile compound in Papilionoidea. Interestingly, methyl anthranilate is widely used as the primary grape flavoring agent in the flavor and fragrance industry, matching the scent emitted by A. polybe. The presence of methyl anthranilate as an androconial constituent, along with aldehydes imparting fruity odors, delineates a unique chemical bouquet among Papilionoidea. This composition likely serves as a sex pheromone and may also fulfill complementary functions, such as predator deterrence.

A new species Epiplema sinica Han & Han, sp. nov.is described from Guangxi Zhuang Autonomous Region and Guangdong, Fujian, Jiangxi, Sichaun, Yunnan Provinces, China. The images of the adults and the genitalia of both sexes are illustrated, and compared with the related species E. albida (Hampson, 1891).

The objective of this study was to know the composition, richness and abundance of Papilionoidea with entomological net, in different environments and distinct periods in the Caatinga biome or Semiarid region during 12 months in the Tamanduá Farm. A total of 5556 individuals were recorded, with 82 species of Papilionoidea in a systematic survey and subsequently 93 species. The estimators of richness or diversity extrapolated from 85.5 (Chao 1) to 121.75 (ChaoRichness - Incidence) and highlighted the ICE with 93.4 species. Hesperiidae and Nymphalidae were the most representative families, followed by others. An unprecedented record was found for Northeast and two for Semiarid-Caatinga, five new records were described to the state of Paraíba and 24 unpublished records for the ecoregion of the Septentrional Sertaneja Depression. The importance of the remaining of ciliary forest for the protection of Papilionoidea was evidenced, allowing the permanence of certain species in the area even in dry period, which has a strong influence on the conservation of this group in population dynamics and community resilience.

Se investigaron los aspectos bioecológicos de Pseudautomeris luteata (Walker, 1865) en la provincia de Misiones, registrándose por primera vez a Belvosia sp. parasitando las pupas y Solanum granulosoleprosum Dunal como planta nutricia de la especie; asimismo, se proporciona una actualización de la distribución de P. luteata en Sudamérica, contribuyendo con información que puede ser utilizada para establecer estrategias de conservación y control para aquellas especies de interés médico o agronómico.

Based on evidence from mitochondrial DNA barcodes, the subspecific rank of the taxon Polyommatus huberti arpaensis Charmeux, 2018 is confirmed. Even though the populations of this species from Vayots Dzor and Gegharkunik show small morphological differences, they are here considered as local variants of P. huberti arpaensis due to lack of differentiation in DNA barcodes. Morphological observations supported by DNA barcode data also revealed a new subspecies, described here as P. pseudactis sevanensis subsp. nov. from the Sevan Lake region (Armenia, Gegharkunik Province).
