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.

Reassessment of the type locality of Euptychiastigmatica Godman, 1905, with the description of two new sibling species from Amazonia (Lepidoptera, Nymphalidae, Satyrinae, Satyrini).

A brief historical review regarding the type locality of Euptychiastigmatica Godman, 1905 was conducted, which suggests that its type locality is actually Rio de Janeiro, Brazil, rather than northeastern Argentina, as previously purported. Consequently, E.stigmatica and its senior synonym E.cyanites Butler, 1871, are regarded to be two species-group names representing a taxon in the euptychiine genus Caeruleuptychia Forster, 1964 known from the Brazilian Atlantic Forest. A lectotype is designated for E.cyanites. Additionally, two closely related species are named and described using an integrative approach with morphological and molecular evidence. Caeruleuptychiaharrisi Nakahara & Freitas, sp. nov. and C.aemulatio Nakahara & Willmott, sp. nov. both occur in Amazonia and COI barcode data recovered these taxa as part of the caerulea clade of Caeruleuptychia.

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.

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.

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.

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.

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.

Before it is too late: description of a new genus and species of butterfly from a highly threatened Brazilian biome

Abstract A new genus, Nhambikuara Freitas, Barbosa & Zacca gen. nov., and species, Nhambikuara cerradensis Freitas, Barbosa & Zacca sp. nov., of the highly diverse Neotropical butterfly subtribe Euptychiina are described. Nhambikuara cerradensis sp. nov. is the type species for the genus, and Euptychia mima Butler, 1867 is also transferred to the new genus, as Nhambikuara mima (Butler, 1867) comb. nov., from the genus Zischkaia Forster, 1964. The taxonomy, phylogenetic relationships, geographic distribution and natural history of species of the genus are also discussed.http://zoobank.org/urn:lsid:zoobank.org:pub:41AD7568-3490-4F63-A019-32D5592A8C44

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.

Documenting diversity in the Amazonian butterfly genus Bia (Lepidoptera, Nymphalidae).

A comparative study of over 1,000 specimens allowed us to revise the taxonomy of the Amazonian butterfly genus Bia. We redescribed the genus, and used a selected set of characters to define and describe new species and subspecific taxa. We found that male genitalia showed little variation among taxa, and that wing and genitalia characters varied independently across the range of the genus. We also noted that species diversification seems to follow a north-south Amazonian divide, with Bia actorion and decaerulea occupying the northern portion of the genus range while the remaining four species are found in southern Amazonia. As defined here Bia includes six species: B. actorion (Linnaeus), B. actorion ecuatoria DeVries & Penz, NEW SSP., B. actorion occulta Casagrande & Penz, NEW SSP., B. decaerulea Weymer STAT. NOV., B. decaerulea cayana Simonsen & Penz, NEW SSP., B. decaerulea pallida Casagrande & Penz, NEW SSP., B. rebeli Bryk STAT. NOV., B. rebeli aegina Penz & Simonsen, NEW SSP., B. rebeli acreana Casagrande & Penz, NEW SSP., B. rebeli arikeme Penz & Casagrande, NEW SSP., B. rebeli pareci Penz & DeVries, NEW SSP., B. rebeli cuprea Penz & Casagrande, NEW SSP., B. rebeli tapajos Penz & Simonsen, NEW SSP., B. caelestis Penz & DeVries, NEW SP., B. pucallpa Casagrande & Penz, NEW SP., and B. peruana Röber.

Description of a new species of Euptychiina (Lepidoptera: Nymphalidae: Satyrinae) from South America.

A new species of Magneuptychia Forster, 1964 (Lepidoptera: Nymphalidae, Satyrinae), Magneuptychia andrei Zacca, Casagrande & Mielke sp. n., is described and illustrated from Venezuela, French Guiana, Trinidad and Tobago and northern Brazil. A comparative diagnosis between the new species and Magneuptychia ocypete (Fabricius, 1776), M. fugitiva Lamas, [1997] and Cissia terrestris (Butler, 1867) is also provided due the similarities in wing pattern.

Taxonomic revision of the "Pierella lamia species group" (Lepidoptera: Nymphalidae: Satyrinae) with descriptions of four new species from Brazil.

Four new species of Pierella Westwood, 1851 from Brazil are described: P. angeloi Zacca, Siewert & Mielke sp. nov. from Maranhão, P. kesselringi Zacca, Siewert & Paluch sp. nov. from Paraíba, Pernambuco, Alagoas and Sergipe, P. nice Zacca, Siewert & Paluch sp. nov. from Bahia and P. keithbrowni Siewert, Zacca & Casagrande sp. nov. from Bahia, Espírito Santo, Rio de Janeiro, São Paulo, Paraná and Santa Catarina. Additionally, P. chalybaea Godman, 1905 stat. rest. and P. boliviana F.M. Brown, 1948 stat. nov. are recognized as valid species and not as subspecies of P. lamia (Sulzer, 1776), while P. l. colombiana Constantino & Salazar, 2007 syn. nov. is synonymized to the former. Lectotype and paralectotype of Papilio dyndimene Cramer, 1779 (a synonym of Pierella lamia) and Pierella chalybaea Godman, 1905 stat. rest. are designated. Habitus and illustrations of male and female genitalia are provided for all species, as well as a geographical distribution map.

Saturniidae and Sphingidae (Lepidoptera, Bombycoidea) assemblage in Vossoroca, Tijucas do Sul, Paraná, Brazil.

The richness and abundance of the assemblage of species in a community are a way to understand the patterns of diversity found around the world. This study describes the assemblages of Saturniidae and Sphingidae in an area of Montana Mixed Ombrophilous Forest, Tijucas do Sul, Paraná, Brazil, 880m, 25º50'8.93"S, 49º 02'55.20"W. Samples were collected between November 2010 and September 2011 during two nights at the twelve new moons periods with a light trap equipped with black light lamp (ultraviolet) of 46 watts between two mercury mixed-light lamps HWL 250 watts from 6:00 p.m to 06:00 a.m. The sampling effort totaled 288 hours. This sampling effort was responsible for the capture of 1235 specimens, distributed in 124 species: 858 specimens and 86 species of Saturniidae, and 377 specimens and 38 species of Sphingidae. It is noteworthy the sampling of 10 new species: one of Automerella Michener, 1949, two of Hylesia Hübner, [1820], one of Lonomia Walker, 1855 and six of Periga Walker, 1855, that will be described.

Two new species of Euptychia Hübner, 1818 from the upper Amazon basin (Lepidoptera, Nymphalidae, Satyrinae).

Two new species of Euptychia Hübner, 1818 are described from the upper Amazon basin: Euptychia attenboroughi Neild, Nakahara, Fratello & Le Crom, sp. n. (type locality: Amazonas, Venezuela), and Euptychia sophiae Zacca, Nakahara, Dolibaina & Dias, sp. n. (type locality: Acre, Brazil). Their unusual facies prompted molecular and phylogenetic analyses of one of the species resulting in support for their classification in monophyletic Euptychia. Diagnostic characters for the two species are presented based on wing morphology, wing pattern, presence of androconial patches on the hindwing, and genitalia. Our results indicate that the projection of the tegumen above the uncus, previously considered a synapomorphy for Euptychia, is not shared by all species in the genus. The adults and their genitalia are documented, and distribution data and a map are provided.

ResumoDuas novas espécies de Euptychia Hübner, 1818 são descritas da bacia do alto Rio Amazonas: Euptychia attenboroughi Neild, Nakahara, Fratello & Le Crom, sp. n. (localidade tipo: Amazonas, Venezuela), Euptychia sophiae Zacca, Nakahara, Dolibaina & Dias, sp. n. (localidade tipo: Acre, Brasil). Suas aparências não usuais levaram a análises molecular e filogenética de uma das espécies que sustentam sua classificação como Euptychia. São apresentados caracteres diagnósticos para as duas espécies baseados na morfologia e no padrão de coloração de suas asas, presença de manchas androconiais nas asas posteriores e suas genitálias. Os resultados indicam que a projeção do tegume sobre o unco, previamente considerada uma sinapomorfia para Euptychia, não é compartilhada por todas as espécies do gênero. São ilustrados os adultos e suas genitálias, bem como dados e mapa de distribuição.

ResumenSe describen dos nuevas especies de Euptychia Hübner, 1818 para la cuenca alta del Río Amazonas: Euptychia attenboroughi Neild, Nakahara, Fratello & Le Crom, sp. n. (localidad típica: Amazonas, Venezuela) y Euptychia sophiae Zacca, Nakahara, Dolibaina & Dias, sp. n. (localidad típica: Acre, Brasil). Sus apariencias inusuales motivaron el análisis molecular y filogenético de una de las especies, lo cual sustenta su clasificación como Euptychia. Se presentan caracteres diagnósticos para las dos especies basados en la morfología y patrón de coloración alar, presencia de parches androconiales en las alas posteriores y sus genitales. Los resultados indican que la proyección del tegumen sobre el uncus, previamente considerada una sinapomorfía para Euptychia, no es compartida por todas las especies del género. Se ilustran los adultos y sus genitales, y se proporcionan datos y mapa de distribución.
