Description of Uniphylus gen. nov., a new genus of Carcharodini (Lepidoptera, Hesperiidae, Pyrginae) for Staphylus evemerus Godman & Salvin, 1896.

Staphylus evemerus Godman & Salvin, 1896 is a species with a unique set of morphological characters within Carcharodini. Also, mitochondrial cytochrome oxidase subunit 1 (COI) sequences analysis demonstrated a large genetic distance with other related genera of the tribe. Therefore, this paper aims to describe a new genus for this species, which is named as Uniphylus gen. nov. Besides the morphological redescription of the male of Uniphylus evemerus (Godman & Salvin, 1896) new comb., the description of the female is provided for the first time, as well as an updated distributional map with all records known so far for this species.

Lessons from the genomic analysis of Hesperiidae (Lepidoptera) holotypes in the MIZA collection (Maracay, Venezuela).

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.

Butterflies (Lepidoptera: Papilionoidea) of Iguaçu National Park and surrounding areas in southern Brazil: a long-term survey, with six new records for the Brazilian fauna / As Borboletas (Lepidoptera: Papilionoidea) do Parque Nacional do Iguaçu e arredores no Sul do Brasil: um inventário de longo prazo, com seis novos registros para a fauna brasileira

Abstract Iguaçu National Park is the second largest (1852.62 km²) protected area in the Atlantic Forest domain and harbors the largest area of semideciduous seasonal forest in Brazil. In this study, we present 795 subspecies and 787 species of butterflies that occur in this protected area and its surrounding areas, collected over 15 years and ten months using different non-standardized sampling methods. We also searched for additional records in the literature, entomological collections, and citizen science platforms on the internet. Among the sampled taxa, six are recorded for the first time in Brazil: Emesis orichalceus Stichel, 1916, Theope p. pakitza Hall & Harvey, 1998 (Riodinidae), Elbella v. viriditas (Skinner, 1920), Apaustus gracilis ssp. n. (Hesperiidae), Deltaya sp. n. (Nymphalidae), and Symbiopsis sp. n. (Lycaenidae). Another six are listed as endangered in lists of butterflies of conservation concern. The records for some species significantly increase previously documented distributions.

Revision of the species of Mythimna Ochsenheimer, 1816 (Pseudaletia) (Lepidoptera: Noctuidae: Noctuinae: Leucaniini) occurring in Brazil

ABSTRACT The genus Mythimna Ochsenheimer, 1816 groups aproximatelly 270 species worldwide. This genus is subdivided into many subgenera and species-groups, with those species occurring in the Neotropical region included in the subgenus Mythimna (Pseudaletia) Franclemont, 1951. Species of this subgenus frequently reach high population levels, causing economic damage to Poaceae cultivars. Hence, it is crucial a well-defined taxonomy allowing rapid and precise identifications. However, the species of this subgenus are cryptic, their recognition requires molecular analyses and in-depth morphological studies, which has often resulted in misidentifications. In Brazil, the occurrence of the following species had been mentioned: Mythimna (P.) adultera (Schaus, 1894), Mythimna (P.) roraimae Franclemont, 1951, Mythimna (P.) sequax Franclemont, 1951, and Mythimna (P.) unipuncta (Haworth, 1809). Yet, until now, we lack a broader knowledge about the geographic distribution and taxonomy of these species. Thus, this study aims to revise the taxonomy of those species based on morphological and molecular (COI) data to provide an updated comprehension of this group in the country. The analysis of 1,664 specimens allowed us to confirm the presence of three species in the country: Mythimna (P.) adultera, Mythimna (P.) sequax, and Mythimna (P.) unipuncta. A lectotype for Mythimna (P.) adultera is designated; a new synonym is proposed: Pseudaletia roraimae syn. nov. of Mythimna (P.) unipuncta; and a new species, Mythimna (P.) celiae sp. nov. is described from Bagé, Rio Grande do Sul, Brazil.

An overview of arginussa species group of Memphis Hbner, [1819], with the description of a new species from Panama (Lepidoptera: Nymphalidae: Charaxinae).

Memphis Hbner, [1819] is a nymphalid butterfly genus exclusive to the Neotropics. It includes species with iridescent bluish or greenish coloration on the upper side of the wings while the underside is cryptic, resembling dead leaves. This paper aims to describe a remarkable new species, M. smalli Riley Dias sp. nov., from the remote Atlantic slopes of Panama based on molecular and morphological analyses. We also review the taxonomy of species herein included in the arginussa species group based on distances analyses of DNA sequence data. The arginussa species group, as defined here, includes M. arginussa (Geyer, 1832), M. eubaena (Boisduval, 1870) stat. rest., M. onophis (Felder Felder, 1861) stat. rest., M. lemons (Druce, 1877), M. neidhoeferi (Rotger, Escalante Coronado, 1965), M. perenna (Godman Salvin, [1884]), M. lankesteri (Hall, 1935) stat. rest., M. paulus Costa Orellana, 2014, M. pithyusa (Felder, 1869), M. herbacea (Butler Druce, 1872) and M. smalli sp. nov. Anaea pithyusa morena Hall, 1935 syn. nov. is recognized as a synonym of Nymphalis pithyusa Felder, 1869. The new species and its closest ally, M. herbacea, are illustrated, including characters of the head, labial palpus, wings, legs, male and female genitalia and their distribution map.

Fifty years without a name: a new species of Splendeuptychia Forster (Lepidoptera: Nymphalidae: Satyrinae).

A new satyrine butterfly species, Splendeuptychia tupinamba Freitas, Huertas Rosa, sp. nov. (Nymphalidae: Satyrinae), is described. This species is found throughout a large geographical range in Brazil, Argentina and Paraguay, predominantly in the Cerrado domain, with some records in neighboring Amazonia and Atlantic Forest. Morphology and molecular data indicate that this species is part of a clade that includes Splendeuptychia ashna (the type species of the genus Splendeuptychia), and several species placed in the recently described genus Nubila Viloria, Andrade Henao, 2019.

A new euptychiine butterfly species from south Brazil and taxonomic rearrangements for Taydebis Freitas, 2013 and Hermeuptychia Forster, 1964 (Lepidoptera: Nymphalidae: Satyrinae).

A new species of Taydebis Freitas, 2003 from south Brazil is described using comparative morphology and species distributions. Also, based on morphology, we transfer Neonympha melobosis Capronnier, 1874 (formerly placed in Paryphthimoides Forster, 1964) to Taydebis, and recognize Euptychia peculiaris Butler, 1874 as its junior synonym (syn. nov.). Furthermore, the monotypic Prenda Freitas Mielke, 2011 is herein treated as junior synonym of Taydebis based on morphology, molecular and ecological evidence. Species of Taydebis are endemic and restricted to south Brazil, and now comprises three species: Taydebis guria Zacca, Casagrande Mielke sp. nov., T. melobosis comb. nov. and T. clarissa Freitas Mielke comb. nov. To continue clarifying Euptychiina taxonomy, Euptychia undulata Butler, 1867 (also formerly placed in Paryphthimoides) is transferred to Hermeuptychia Forster, 1964, and we provide additional information on its taxonomy, morphology, and distribution. Diagnoses, illustrations, and distributional maps are provided for all taxa except T. clarissa comb. nov.

The Granulate Cutworm (Lepidoptera: Noctuidae): Biological Parameters Under Controlled Conditions, Host Plants, and Distribution in the Americas.

Feltia subterranea (Fabricius), commonly known as the granulate cutworm, is a common species of owlet moths (Noctuidae) of major agricultural importance, widely distributed in Nearctic and Neotropical regions. This study was conducted to determine the species biological parameters, gather information about its larval host plants, and assess the agricultural significance of this species in the Americas. The viability of the egg, larval, pupal stages, and prepupal period was 98, 98, and 100%, respectively, under laboratory conditions. The average duration of the egg, larval, pupal stages, and prepupal period was 3, 17, 4, and 13 d, respectively. All laboratory-reared larvae developed through five instars. The growth ratio was 1.93 for females and 1.85 for males. The duration of the larval stage was significantly longer in females than in males from the fourth instar. The duration of the pupal stage was significantly shorter in females than in males. When larval and pupal stage durations were combined, there were no significant differences in total development time as a function of sex. In total, 159 botanical taxa belonging to 41 families were recorded as host species for F. subterranea. The families with the greatest number of host species were Fabaceae (22), Poaceae (19), Asteraceae (16), Brassicaceae (13), Solanaceae (12), Amaranthaceae (7), Cucurbitaceae (7), and Malvaceae (5). It is noteworthy that the large number of native weeds used by F. subterranea as host plants could represent a significant source of infestation of crops in the agricultural landscape.

Altitudinal variation in butterfly community associated with climate and vegetation.

Elevation creates a variety of physical conditions in a relatively short distance, which makes mountains suitable for studying the effects of climate change on biodiversity. We investigated the importance of climate and vegetation for the distribution of butterflies from 800 to 1400 m elevation. We sampled butterflies, and woody and rosette plants and measured air temperature and humidity, wind speed and gust, and solar radiation. We partitioned diversity to assess the processes underlying community shifts across altitudes - species loss versus replacement. We assessed the strength of the association among butterfly, vegetation, and climate. Butterfly richness and abundance decreased with altitude, and species composition changed along the elevation. Changes in butterfly composition with altitude were mainly through species replacement and by abundance increases in some species being compensated by decreases in others. Since the floristic diversity decreased with altitude due to soil conditions, and butterflies are closely related to their host plants, this could explain species replacement with altitude. Overall, we found a stronger association of butterfly community with vegetation than climate, but plant community and climate were also strongly associated between them. Butterfly richness was more strongly associated with plant richness than with temperature, while the reverse was true for butterfly abundance, which was more strongly associated with temperature than with plant richness. We must consider the complementary roles of resource and conditions in species distribution.

A new species of Pheraeus Godman, 1900 (Hesperiidae, Hesperiini, Moncina) restricted to Rio Doce Valley, Brazil.

A new species of Pheraeus Godman, 1900, P. guandu Saraiva, Carneiro, Mielke Casagrande sp. nov., restricted to the Rio Doce Valley (Espírito Santo and Minas Gerais, southeast Brazil) is described. Adults of the new species are illustrated and compared with phenotypically closest species, Pheraeus argynnis (Plötz, 1884), together with the diagnostic characters present in the male and female genitalia. This new species is here solely described because it is known to occur in a restricted region crossed by the Rio Doce. This region has been extensively transformed in recent decades by agriculture, livestock, construction of hydroelectric and tailing dams, and more recently by a dam failure, thus potentially impacting the habitat of this species.

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. similis (Butler, 1867) comb. rest. and V. themis (Butler, 1867) comb. nov. Vanima Zacca, Casagrande Mielke gen. nov. is described to contain Euptychia labe Butler, 1870 (the type species), E. palladia Butler, 1867 and E. lesbia Staudinger, [1886]. The taxonomy of these two genera was initially revised based on morphological and distributional data, and subsequently tested and supported with a Maximum Likelihood analysis using four genes (COI, GAPDH, RpS5 and EF1-a). Lectotypes are designated for Euptychia similis Butler, 1867, E. themis Butler, 1867, E. undina Butler, 1870 and E. lesbia Staudinger, [1886]. No DNA sequences were obtained for Euptychia cleophes Godman Salvin, 1889 but its transfer to Megisto Hübner, [1819] is supported by morphological evidence. For all taxa treated in this study, a taxonomic catalog, diagnosis, (re)description and illustrations of adults, venation and genitalia are provided, as well as comments on intraspecific variation, sexual dichromatism, ecology and distribution maps.

Oviposition of Minstrellus grandis (Lepidoptera: Riodinidae) in a harmful ant-plant symbiosi

The oviposition behavior of the rare butterfly Minstrellus grandis (Callaghan, 1999) (Lepidoptera: Riodinidae) is recorded for the first time. Two females laid eggs on the old leaves of an unidentified Triplaris sp. (Polygonaceae), a myrmecophytic plant typically known as 'Triplaria' or 'novice' tree, inhabited by aggressive 'taxi' ants of the genus Pseudomyrmex sp. (Hymenoptera: Formicidae). These observations suggest that M. grandis caterpillars live associated with one of the most harmful types of Amazon ant-plant symbiosis. (AU)

Flight over the Proto-Caribbean seaway: Phylogeny and macroevolution of Neotropical Anaeini leafwing butterflies.

Our understanding of the origin and evolution of the astonishing Neotropical biodiversity remains somewhat limited. In particular, decoupling the respective impacts of biotic and abiotic factors on the macroevolution of clades is paramount to understand biodiversity assemblage in this region. We present the first comprehensive molecular phylogeny for the Neotropical Anaeini leafwing butterflies (Nymphalidae, Charaxinae) and, applying likelihood-based methods, we test the impact of major abiotic (Andean orogeny, Central American highland orogeny, Proto-Caribbean seaway closure, Quaternary glaciations) and biotic (host plant association) factors on their macroevolution. We infer a robust phylogenetic hypothesis for the tribe despite moderate support in some derived clades. Our phylogenetic inference recovers the genus Polygrapha Staudinger, [1887] as polyphyletic, rendering the genera FountaineaRydon, 1971 and Memphis Hübner, [1819] paraphyletic. Consequently, we transfer Polygrapha tyrianthina (Salvin & Godman, 1868) comb. nov. to Fountainea and Polygrapha xenocrates (Westwood, 1850) comb. nov. to Memphis. We infer an origin of the group in the late Eocene ca. 40 million years ago in Central American lowlands which at the time were separated from South America by the Proto-Caribbean seaway. The biogeographical history of the group is very dynamic, with several oversea colonization events from Central America into the Chocó and Andean regions during intense stages of Andean orogeny. These events coincide with the emergence of an archipelagic setting between Central America and northern South America in the mid-Miocene that likely facilitated dispersal across the now-vanished Proto-Caribbean seaway. The Amazonian region also played a central role in the diversification of the Anaeini, acting both as a museum and a cradle of diversity. We recover a diversification rate shift in the Miocene within the species-rich genus Memphis. State speciation and extinction models recover a significant relationship between this rate shift and host plant association, indicating a positive role on speciation rates of a switch between Malpighiales and new plant orders. We find less support for a role of abiotic factors including the progressive Andean orogeny, Proto-Caribbean seaway closure and Quaternary glaciations. Miocene host plant shifts possibly acted in concert with abiotic and/or biotic factors to shape the diversification of Anaeini butterflies.

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

We here propose a new, monotypic genus, Amiga Nakahara, Willmott & Espeland, gen. n., to harbor a common Neotropical butterfly, described as Papilioarnaca Fabricius, 1776, and hitherto placed in the genus Chloreuptychia Forster, 1964. Recent and ongoing molecular phylogenetic research has shown Chloreuptychia to be polyphyletic, with C.arnaca proving to be unrelated to remaining species and not readily placed in any other described genus. Amigaarnaca gen. n. et comb. n. as treated here is a widely distributed and very common species ranging from southern Mexico to southern Brazil. A neotype is designated for the names Papilioarnaca and its junior synonym, Papilioebusa Cramer, 1780, resulting in the treatment of the latter name as a junior objective synonym of the former. A lectotype is designated for Euptychiasericeella Bates, 1865, which is treated as a subspecies, Amigaarnacasericeella (Bates, 1865), comb. n. et stat. n., based on molecular and morphological evidence. We also describe two new taxa, Amigaarnacaadela Nakahara & Espeland, ssp. n. and Amigaarnacaindianacristoi Nakahara & Marín, ssp. n., new subspecies from the western Andes and eastern Central America, and northern Venezuela, respectively.

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. Additionally, the monophyly of the clade remains uncertain, with Euptychia possibly not being closely related to the remainder of the clade. Here we present a backbone phylogeny of the subtribe based on 106 taxa, 368 nuclear loci, and over 180,000 bps obtained through hybrid enrichment. Using both concatenation and species tree approaches (IQ-TREE, EXABAYES, ASTRAL), we can for the first time strongly confirm the monophyly of Euptychiina with Euptychia being the sister group to the remainder of the clade. The Euptychiina is divided into nine well supported clades, but the placement of a few genera such as Hermeuptychia, Pindis and the Chloreuptychia catharina group still remain uncertain. As partially indicated in previous studies, the genera Cissia, Chloreuptychia, Magneuptychia, Megisto, Splendeuptychia and Euptychoides, among others, were found to be highly polyphyletic and revisions are in preparation. The phylogeny will provide a strong backbone for the analysis of datasets in development that are much more taxonomically comprehensive but have orders of magnitude fewer loci. This study therefore represents a critical step towards resolving the higher classification and studying the evolution of this highly diverse lineage.

Butterflies (Lepidoptera: Papilionoidea) of an urban park in northeastern Brazil / As borboletas (Lepidoptera: Papilionoidea) de um parque urbano do nordeste do Brasil

Abstract Despite being one of the groups most well studied in Brazil, the butterfly fauna of northeastern Brazil, especially north of the mouth of São Francisco River, is poorly known. The aim of this study was to inventory the butterfly fauna in a remnant of Atlantic Forest in the state of Pernambuco as a contribution to understanding the distribution of these insects. The study was carried out in a 384.7 hectares fragment of Parque Estadual Dois Irmãos, in the metropolitan region of Recife. The butterflies were sampled monthly with insect nets from August 2011 to July 2012 and from January to August 2016. Additional records were obtained from two entomological collections and from two previous visits to the area in July 2003 and August 2006. A total of 273 species was sampled in 464 hours, with an additional 15 species recorded from the Entomological Collections, totaling 288 butterfly species recorded. The richest family was Hesperiidae (108 species), followed by Nymphalidae (80), Lycaenidae (43) Riodinidae (37), Pieridae (16) and Papilionidae (4). The fauna was dominated by generalist species with a broad geographical distribution, many of them commonly found on open areas, forest edges and secondary vegetation. Roeberella lencates (Hewitson, 1875) and Pheles atricolor atricolor (Butler, 1871) (Riodinidae) represent new records for northeastern Brazil.

Resumo Apesar de ser um dos grupos mais bem estudados no Brasil, as borboletas da região Nordeste, especialmente ao norte da foz do Rio São Francisco, são ainda pouco conhecidas. O objetivo deste estudo foi realizar um inventário da fauna de borboletas em um fragmento de Floresta Atlântica no estado de Pernambuco, como uma contribuição para compreensão sobre a distribuição desses insetos. O estudo foi realizado em um fragmento de Floresta Atlântica de 384.7 hectares do Parque Estadual Dois Irmãos, localizado na região metropolitana de Recife. As borboletas foram amostradas mensalmente, de agosto de 2011 a julho de 2012 e de janeiro a agosto de 2016, com auxílio de redes entomológicas. Registros adicionais foram obtidos de duas Coleções Entomológicas e de duas coletas prévias em julho de 2003 e agosto de 2006. Um total de 273 espécies foi registrado em 464 horas e 15 espécies adicionais registradas a partir de Coleções Entomológicas, totalizando 288 espécies de borboletas registradas. A família mais rica foi Hesperiidae (108 espécies), seguida por Nymphalidae (80), Lycaenidae (43), Riodinidae (37), Pieridae (16) e Papilionidae (4). A fauna de borboletas foi dominada por espécies generalistas com uma ampla distribuição geográfica, muitas delas encontradas comumente em áreas abertas, bordas de mata e em vegetação secundária.

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. ocypete. A neotype for Papilio ocypete Fabricius, 1776 is designated and its redescription is provided. Neonympha sabina C. Felder R. Felder, 1867 and Euptychia helle var. olivacea Aurivillius, 1929 are treated as junior subjective synonyms of P. ocypete and a lectotype is designated for each name. A neotype for the preoccupied name Papilio helle Cramer, 1779, and its replacement name Magneuptychia fugitiva Lamas, [1997], is also designated, and a redescription of this name and discussion of its taxonomic status are provided. We describe an additional phenotypically similar species, Magneuptychia kamel Benmesbah Zacca, sp. n. from the western Amazon and raise the name Magneuptychia opima sheba Brévignon Benmesbah, 2012 to species rank (stat. rev.) on the basis of morphological and DNA sequence evidence. We also discuss the difficulties regarding taxonomic and geographical delimitation in these complex species groups. Observations on Euptychiina behaviour are also provided. Finally, based on external characters and male genitalia, a proposed preliminary arrangement of two species groups is proposed, including other species of Magneuptychia Forster, 1964 and Cissia Doubleday, 1848.

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. The taxonomic status of Y. patricia is re-examined, and a detailed redescription of the adult morphology, including the male genitalia, is presented. Information on the distribution, habitat and immature stages of Y. patricia is also provided. Yphthimoides patricia is clearly a distinct species from Y. manasses based on the analysis of DNA barcode sequences and the morphology of the male genitalia.

Resurgence of a forgotten Southern Brazil endemic species: taxonomic position, redescription, and spatio-temporal distribution of Porosagrotis carolia Schaus, 1929 (Lepidoptera: Noctuidae: Noctuinae).

The taxonomy of the hitherto unplaced taxon Porosagrotis carolia Schaus, 1929 is evaluated and the name is taken out of taxonomic limbo and combined with Feltia Walker, 1856. Feltia carolia comb. nov., described from a single female specimen, is redescribed, including the first description of the male. Head, thorax and its appendages, and male and female genitalia are illustrated through photographs and line drawings; photographs of the holotype and a distribution map for the species is provided. Additionally, the spatio-temporal occurrence of the species in Rio Grande do Sul was assessed by monthly standardized samplings with light traps from January of 1998 to December of 1999 in ten different physiographical zones of the state. Our results suggest that F. carolia comb. nov. is univoltine and goes through prepupal and pupal estival diapauses. The assessment of the distribution of the species, based on the standardized samplings and specimens deposited in entomological collections, suggests that F. carolia comb. nov. is restricted to the southern Brazilian Campos, a mostly neglected environment discontinuously distributed in mountainous plateaus of the southern Mata Atlântica biome.
