Systematics of Dynastor Doubleday, [1849] (Lepidoptera: Nymphalidae, Satyrinae, Brassolini).

Dynastor Doubleday, [1849] (Lepidoptera: Nymphalidae: Satyrinae: Brassolini) is an exclusively Neotropical genus, occurring from Mexico to Argentina. Adults have crepuscular habits, while the larvae are unique in Brassolini in feeding on bromeliads (Bromeliaceae). Until now, Dynastor contained three species, nine subspecies, and five synonyms (two of them generic synonyms).

Checklist of Yunnan Papilionidae (Lepidoptera: Papilionoidea) with nomenclatural notes and descriptions of new subspecies.

A checklist of the Papilionidae of Yunnan is presented, with nomenclatural and taxonomic changes made. In the nomenclatural section, the junior homonym Papilio bootes nigricans Rothschild, 1895 is replaced by Papilio bootes nigricauda Lamas & Cotton nom. nov.

A global phylogeny of butterflies reveals their evolutionary history, ancestral hosts and biogeographic origins.

Butterflies are a diverse and charismatic insect group that are thought to have evolved with plants and dispersed throughout the world in response to key geological events. However, these hypotheses have not been extensively tested because a comprehensive phylogenetic framework and datasets for butterfly larval hosts and global distributions are lacking. We sequenced 391 genes from nearly 2,300 butterfly species, sampled from 90 countries and 28 specimen collections, to reconstruct a new phylogenomic tree of butterflies representing 92% of all genera.

A peculiar new species of Dione (Agraulis) Boisduval & Le Conte (Lepidoptera, Nymphalidae, Heliconiinae) associated with Ruiz & Pavón (Passifloraceae) in xeric western slopes of the Andes.

Butterflies associated with xerophytic environments of the Andes have been little studied, and they exhibit high levels of endemism. Herein Dione (Agraulis) dodona Lamas & Farfán, (Nymphalidae; Heliconiinae) is described, distributed on the western slopes of the Andes of Peru and northern Chile, between 800 and 3,000 m elevation. Adults of both sexes, and the immature stages, are described and illustrated based on light and scanning electron microscopy.

Lost and Found: Taxonomic Notes on Some Butterflies (Lepidoptera: Papilionoidea) from J.F. Zikán found on F. Dissmann's Collection.

J. F. Zikán described several new taxa of butterflies from the Neotropical region.

Neotype designation for Walch, 1775 (Hesperiidae: Eudaminae).

The discovery that a skipper butterfly (Walch, 1775), previously placed in the genus Hübner, [1819], is a complex of many similar-looking species-level taxa with different COI barcodes, caterpillar foodplants and body patterns, and subtle differences in adult phenotypes raised a question about which species is the original . To answer this question, being unable to locate its holotype, we designate the of Walch, 1775, a female specimen from Suriname in the Zoological State Collection, Munich, Germany. This neotype will form the foundation for a comprehensive revision of the complex based on genomic sequencing and analysis augmented with phenotypic considerations.

Taxonomic discoveries enabled by genomic analysis of butterflies.

The comparative genomics of butterflies yields additional insights into their phylogeny and classification that are compiled here. As a result, 3 genera, 5 subgenera, 5 species, and 3 subspecies are proposed as new, i.e.

Considerations on the Systematics of Neotropical Pierina, with the Description of Two New Species of Phulia Herrich-Schäffer from the Peruvian Andes (Lepidoptera: Pieridae, Pierinae, Pierini).

A comparative analysis of high-Andean Pierina was carried out, including a total of 25 species. Based on morphological evidence, with an emphasis on venation and genitalia and molecular data, using three genetic markers, we confirm the recent subjective synonymy of the generic names Tatochila Butler, 1870, Piercolias, Staudinger, 1894, Hypsochila Ureta, 1955, Infraphulia Field, 1958, Pierphulia Field, 1958, and Theochila Field, 1958 with Phulia Herrich-Schäffer, 1867. Two new species are described, namely Phulia stoddardi Pyrcz & Cerdeña n.

LepTraits 1.0 A globally comprehensive dataset of butterfly traits.

Here, we present the largest, global dataset of Lepidopteran traits, focusing initially on butterflies (ca. 12,500 species records). These traits are derived from field guides, taxonomic treatments, and other literature resources.

Genomics-based higher classification of the species-rich Hairstreaks (Lepidoptera: Lycaenidae: Eumaeini).

We propose a higher classification of the lycaenid hairstreak tribe Eumaeini - one of the youngest and most species-rich butterfly tribes - based on autosome, Lepidopteran Z sex chromosome, and mitochondrial protein-coding genes. The subtribe Neolycaenina Korb is a of Callophryidina Tutt, and subtribe Tmolusina Bálint is a of Strephonotina K. Johnson, Austin, Le Crom, & Salazar.

Two new species of from North America and three neotype designations (Nymphalidae: Satyrinae).

Two new species of Forster, 1964 are described. Grishin, . (type locality Guatemala: El Progreso, Morazán) is an isolated member of the genus that does not readily fit into known species groups, as suggested by its distinct male and female genitalia and COI DNA barcode sequences.

Conserved ancestral tropical niche but different continental histories explain the latitudinal diversity gradient in brush-footed butterflies.

The global increase in species richness toward the tropics across continents and taxonomic groups, referred to as the latitudinal diversity gradient, stimulated the formulation of many hypotheses to explain the underlying mechanisms of this pattern. We evaluate several of these hypotheses to explain spatial diversity patterns in a butterfly family, the Nymphalidae, by assessing the contributions of speciation, extinction, and dispersal, and also the extent to which these processes differ among regions at the same latitude. We generate a time-calibrated phylogeny containing 2,866 nymphalid species (~45% of extant diversity).

Evolutionary trade-offs between male secondary sexual traits revealed by a phylogeny of the hyperdiverse tribe Eumaeini (Lepidoptera: Lycaenidae).

Male butterflies in the hyperdiverse tribe Eumaeini possess an unusually complex and diverse repertoire of secondary sexual characteristics involved in pheromone production and dissemination. Maintaining multiple sexually selected traits is likely to be metabolically costly, potentially resulting in trade-offs in the evolution of male signals. However, a phylogenetic framework to test hypotheses regarding the evolution and maintenance of male sexual traits in Eumaeini has been lacking.

Description of a new genus and species for a common and widespread Amazonian satyrine butterfly (Lepidoptera: Nymphalidae: Satyrinae: Satyrini).

We here propose a new monotypic butterfly genus Nakahara & Espeland, to accommodate a new species, Lamas & Nakahara, , described and named herein. is a relatively common and widespread butterfly species which is recovered as a member of the so-called " clade" in the nymphalid subtribe Euptychiina, based on our molecular phylogenetic analysis using a maximum likelihood approach. Nevertheless, its sister group is not confidently resolved in any analysis, supporting a relatively distant relationship to any described genus as well as our decision to establish a new monotypic genus.

Revalidation of Vareuptychia Forster, 1964, description of Vanima gen. nov., and notes on Euptychia cleophes Godman amp; Salvin, 1889 (Lepidoptera: Nymphalidae: Satyrinae).

Vareuptychia Forster, 1964 stat. rest. is revalidated and comprises two species, V.

A new species of the genus Mathania Oberthür, 1890, M. hughesi Lamas, Farfán Cerdeña, sp. n.

A review of the article "A new genus and two new species of Lepidoptera Satyridae, Sphingidae from Yunnan China" by D.-Z. Dong et al. (2018).

A taxonomic paper describing supposedly new Lepidoptera taxa was recently published (Dong et al. 2018) in a fully electronic and purely online journal, with ISSN-Online: 2313-7177, available from http://www.ghrnet.

A revision of the new genus Nakahara, Willmott & Espeland, gen. n., described for Fabricius, 1776 (Lepidoptera, Nymphalidae, Satyrinae).

We here propose a new, monotypic genus, Nakahara, Willmott & Espeland, , to harbor a common Neotropical butterfly, described as Fabricius, 1776, and hitherto placed in the genus Forster, 1964. Recent and ongoing molecular phylogenetic research has shown to be polyphyletic, with proving to be unrelated to remaining species and not readily placed in any other described genus. as treated here is a widely distributed and very common species ranging from southern Mexico to southern Brazil.

An updated checklist of the European Butterflies (Lepidoptera, Papilionoidea).

This paper presents an updated checklist of the butterflies of Europe, together with their original name combinations, and their occurrence status in each European country. According to this checklist, 496 species of the superfamily Papilionoidea occur in Europe. Changes in comparison with the last version (2.

Four hundred shades of brown: Higher level phylogeny of the problematic Euptychiina (Lepidoptera, Nymphalidae, Satyrinae) based on hybrid enrichment data.

Relationships within satyrine butterflies have been notoriously difficult to resolve using both morphology and Sanger sequencing methods, and this is particularly true for the mainly Neotropical subtribe Euptychiina, which contains about 400 described species. Known larvae of Euptychiina feed on grasses and sedges, with the exception of the genus Euptychia, which feed on mosses and lycopsids, and the butterflies occur widely in rainforest, cloudforest and grassland habitats, where they are often abundant. Several previous molecular and morphological studies have made significant progress in tackling the systematics of the group, but many relationships remain unresolved, with long-branch-attraction artifacts being a major problem.

Redescription of Yphthimoides patricia (Hayward, 1957), with taxonomic notes on the names Euptychia saltuensis Hayward, 1962 and Yphthimoides manasses (C. Felder R. Felder, 1867) (Nymphalidae: Satyrinae).

Euptychia saltuensis Hayward, 1962, new synonym, currently regarded as a nomen dubium and possibly a junior subjective synonym of Yphthimoides manasses (C. Felder R. Felder, 1867), is here treated as a junior subjective synonym of Yphthimoides patricia (Hayward, 1957), based on morphological characters of the male genitalia and the DNA barcode.

Taxonomic notes on Papilio ocypete Fabricius, 1776 and Papilio helle Cramer, 1779 with description of two new similar species from South America (Lepidoptera: Nymphalidae: Satyrinae).

The discovery of a new species of satyrine butterfly, Magneuptychia louisammour Benmesbah Zacca, sp. n., that is phenotypically similar to a sympatric species widely known as Magneuptychia ocypete (Fabricius, 1776), led to a review of the taxonomic status of M.
