Hesperiidae of Rondônia, Brazil: Porphyrogenes Watson (Lepidoptera: Pyrginae: Eudamini), with descriptions of new species from Central and South America

The pyrgine genus Porphyrogenes Watson, 1893 (Hesperiidae) is discussed, especially as it occurs in central Rondônia, Brazil. Of eleven species of Porphyrogenes found in Rondônia, four (P. specularis, P. convexus, P. sparus, and P. spadix) are described as new species. Biological details of the genus are discussed. An additional five new species of Porphyrogenes (P. spina, P. sporta, P. splendidus, P. simulator, and P. speciosus) are described from elsewhere. Porphyrogenes cervinus (Plötz, 1883), new synonym of Porphyrogenes ferruginea (Plötz, 1883), reinstated status, is raised from a subspecies of Porphyrogenes despecta (Butler, 1870) to species-level. Porphyrogenes omphale (Butler, 1871), reinstated status, is not synonymous with Porphyrogenes passalus (Herrich-Schäffer, 1869) and becomes a species-level taxon for which no subspecies are recognized; P. passalus was described from a female with no known male. Porphyrogenes sula Williams and Bell, 1940, reinstated status, is raised from synonymy with Porphyrogenes zohra (Möschler, 1879) to species-level. Porphyrogenes stresa Evans, 1952, new status, is raised from a subspecies of P. zohra to species-level. Porphyrogenes immaculata (Skinner, 1920), new synonymy, was described from a male, which we believe is the male of Porphyrogenes sororcula (Mabille and Boullet, 1912). Porphyrogenes suva Evans, 1952, new synonymy, formerly considered a full species, was described from a male which we believe is the male of, and thus synonymous with, Porphyrogenes probus (Möschler, 1877). Porphyrogenes virgatus (Mabille, 1888) and Porphyrogenes eudemus (Mabille, 1888), considered synonyms of P. zohra and Porphyrogenes vulpecula (Plötz, 1882), respectively, without justification by Evans (1952), are removed from those synonymies and retained, along with P. passalus, as females without confirmed affinities. Lectotypes are here designated for Phareas ferruginea Plötz, 1883; Augiades despecta Butler, 1870; Telegonus omphale Butler, 1871; Eudamus pausias Hewitson, 1867; Telegonus probus Möschler, 1877; Telemiades vulpecula Plötz, 1882; Eudamus passalus Herrich-Schäffer, 1869; Thymele virgatus Mabille, 1888; and Thymele eudemus Mabille, 1888. A neotype is designated for Phareas cervinus Plötz, 1883, that being the lectotype of Phareas ferruginea. Types of all taxa in the genus are illustrated. Three named and five unnamed phenotypes of females, not reconciled with males, are identified and described. Twenty-six species are now recognized, making this one of the largest hesperiid genera in the neotropics

Thorax and abdomen morphology of some Neotropical Hesperiidae (Lepidoptera)

The external morphology of the thorax and abdomen of four species of Neotropical Hesperiidae, belonging to different tribes, are described and illustrated. The morphological characters traditionally used in the classification of the family are reviewed and new information is added with emphasis on the characters usually neglected in the classification and identification of Hesperiidae and Lepidoptera. The use of these characters, along with those commonly used in literature for the identification and taxonomy of the family, is discussed, aiming to contribute to comparative studies of morphology and taxonomy of this group. A morfologia externa do tórax e abdômen de quatro espécies de Hesperiidae neotropicais, pertencentes a diferentes tribos na família são ilustradas e descritas. Os caracteres morfológicos tradicionalmente utilizados na classificação da família foram revistos e novas informações são acrescentadas enfatizando os caracteres usualmente negligenciados na classificação e identificação de Hesperiidae e Lepidoptera. O uso destes caracteres é discutido quanto à sua potencial utilidade na identificação e taxonomia da família, além dos comumente utilizados na literatura, objetivando contribuir para estudos de morfologia comparativa e taxonomia do grupo

An annotated list of Symmachia Hübner, [1819] (Lepidoptera: Riodinidae: Symmachiini) from Parque Nacional da Serra do Divisor, Acre, Brazil, with the description of a new species

We provide an illustrated list of species belonging to the genus Symmachia Hübner, [1819] (Lepidoptera: Riodinidae: Symmachiini) collected during an expedition conducted between September 10-21, 2011 in the northern part of the Parque Nacional da Serra do Divisor, Acre, Brazil, a remote region of Amazon rainforest. A total of 46 individuals were collected belonging to 15 species. For all recorded species, drawings of male genitalia and behavioral information are provided to support future studies on the taxonomy of the group. A new species, Symmachia divisora Dolibaina and Leite, sp. nov., is described, and a revised status for Symmachia hetaerina hesione Stichel, 1910, stat. rev., is proposed.Fornecemos a lista ilustrada das espécies pertencentes ao gênero Symmachia Hübner, [1819] (Lepidoptera: Riodinidae: Symmachiini) coletadas durante uma expedição entre os dias 10-21 de setembro de 2011 na porção norte do Parque Nacional da Serra do Divisor, Acre, Brasil, uma remota região de Floresta Amazônica. Ao total foram coletados 46 indivíduos pertencentes a 15 espécies. Para todas as espécies registradas são fornecidos desenhos da genitália masculina e informações de comportamento, com a finalidade de subsidiar futuros trabalhos sobre a taxonomia do grupo. Uma nova espécie, Symmachia divisora Dolibaina and Leite, sp. nov., é descrita, assim como é proposto um status revalidado para Symmachia hetaerina hesione Stichel, 1910, stat. rev.

New Paraguayan Specimens and First Confirmed Phenological Data for Catharisa cerina Jordan, 1911 (Lepidoptera: Saturniidae)

Phenological data is provided for the first time for the little known and recently rediscovered Saturniid Catharisa cerina Jordan, 1911. The species exhibits at least two annual flights, which are possibly associated with the onset of the rains.(Uma nova espécie paraguaia e primeiros dados fenológicos confirmados para Catharisa cerina Jordan, 1911 (Lepidoptera: Saturniidae)). Dados fenológicos são fornecidos pela primeira vez para a mariposa Saturniidae Catharisa cerina Jordan 1911, recentemente redescoberta e pouco conhecida. Esta espécie exibe pelo menos dois vôos anuais, possivelmente associados com o aparecimento das chuvas

Notes on the distribution of Memphis montesino Pyrcz, 1995 and Memphis boliviana (Druce, 1977 (Insecta: Lepidoptera): New country records and updated geographic distribution maps

This paper provides two new distribution records from Guyana for Memphis montesino Pyrcz, 1995, extending the distribution of the species over 200 km westwards to lowland moist forests; and the first record for Memphis boliviana (Druce, 1977) from Argentina, extending its distribution over 500 km southwards

A new genus, Atlanteuptychia gen. nov., for Euptychia ernestina (Lepidoptera: Nymphalidae: Satyrinae)

Atlanteuptychia Freitas, Barbosa & Mielke, gen. nov. is proposed for Euptychia ernestina Weymer, 1911 and illustrated. This taxon lacks the posterior projection of the tegumen, a synapomorphy of Euptychia Hübner, 1818, and does not share morphological synapomorphies with Cyllopsis R. Felder, 1869 and Paramacera Butler, 1868, two Central American genera apparently closely related to Euptychia ernestina, based on molecular data. This evidence supports the proposition of a new genus endemic to the Atlantic Forest, A. ernestina stat. nov.66166

Butterflies (Lepidoptera, Papilionoidea and Hesperioidea) of the "Baixada Santista" region, coastal São Paulo, southeastern Brazil

Butterflies (Lepidoptera, Papilionoidea and Hesperioidea) of the "Baixada Santista" region, coastal São Paulo, southeastern Brazil. A list with 538 species of butterflies recorded in the Baixada Santista, São Paulo (SE Brazil) is presented. Standard sampling protocols (i.e. with entomological nets) were followed. Baited traps were installed for fruit feeding species. Data from the literature and entomological collections were also considered in the total estimated species richness. The species richness recorded in the Baixada Santista region represents about 16% of the Brazilian butterfly fauna, and 34% of the known butterfly fauna for the state of São Paulo. The present list contains an appreciably higher number of species in comparison to other lists from similar biomes farther south, such as Blumenau in Santa Catarina, and Maquiné in Rio Grande do Sul5515568CONSELHO NACIONAL DE DESENVOLVIMENTO CIENTÍFICO E TECNOLÓGICO - CNPQFUNDAÇÃO DE AMPARO À PESQUISA DO ESTADO DE SÃO PAULO - FAPESP300282/2008–700/01484–1; 04/05269–9; 98/05101–8; 02/13898– 0; 03/05895–4Borboletas (Lepidoptera, Papilionoidea e Hesperioidea) da região da Baixada Santista, litoral de São Paulo (SE Brasil).
