A new species of Lepidoptera (Papilionoidea) is described on the basis of specimens collected at upper elevations in the Guiana Shield: Thaeides hyperion Bálint, Costa & Grishin, n. sp. (Lycaenidae: Theclinae: Eumaeini). Due to its adaptation to mountainous areas, it is probably a taxon endemic to the biogeographic Pantepui Province. With 16 figure...
Hybridization allows adaptations to be shared among lineages and may trigger the evolution of new species1,2. However, convincing examples of homoploid hybrid speciation remain rare because it is challenging to demonstrate that hybridization was crucial in generating reproductive isolation³. Here we combine population genomic analysis with quantita...
A new subspecies of Lepidoptera (Papilionoidea) is described from the Pantepui: Heliconius elevatus jigginsi Costa & Neild, n. ssp. (Nymphalidae, Heliconiinae, Heliconiini) from Auyán Tepui (Venezuela), probably strictly endemic to the Auyán Massif. A new synonymy is proposed: Heliconius elevatus sonjae Neukirchen, 1997, n. syn. of Heliconius eleva...
Genomic sequencing and analysis of holotypes from the MIZA collection (Maracay, Venezuela) and their comparison with other species and their type specimens advances our understanding of their taxonomy. Jemadia demarmelsi Orellana, [2010] is confirmed as a species-level taxon and its female is genetically verified. The following are species-level ta...
Zegara fernandezi (González, 1992) (Castniidae, Castniinae) is a little-known butterfly-moth due to its rarity.

Abstract
Members of the speciose subtribe Pronophilina (Nymphalidae: Satyrinae) are Neotropical butterflies predominantly found in cloud forests. A few species live exclusively in open habitats above the tree line: paramo and puna biomes. This habit requires special adaptation to particular physical and climatic conditions of the oreal zone in the...
