Borboletas (Papilionoidea e Hesperioidea) de Guarapuava e arredores, Paraná, Brasil: um inventário com base em 63 anos de registros

Despite figuring among the countries with high diversity of butterflies, Brazil has little information available of its biodiversity. Parana is one of brazilian states with the less known lepidopteran fauna. Only Curitiba and vicinity have a list of butterflies species published, while all other Parana regions lack such information. Aiming to provide new informations about the butterflies fauna in Parana state, this study compiles information of 63 years of collect (1944 to 2002 and from 2005 to 2010) in Guarapuava and vicinity, south-central Parana, and emphasizes the typical grassland species, now nearly extinct in this region. Were recorded 689 species, 264 of these were recorded only in one of the sampling periods. About 6% are typical grassland species and fewer than half of those were recorded recently. Pieridae, Nymphalidae and Papilionidae latest records are more similar to earlier records than Riodinidae, Hesperiidae, and Lycaenidae. We suggest the creation of permanent conservation areas comprising grasslands, as they encompass a unique fauna and are threatened locally; furthermore, they are not protected by any conservation areas already established in the region.

Two new species of Esthemopsis C. Felder & R. Felder, 1865 (Lepidoptera: Riodinidae: Symmachiini) from southeastern and northeastern Brazil, with taxonomic comments on Esthemopsis teras (Stichel, 1910) stat. rev. and Esthemopsis pallida Lathy, 1932 stat. nov.

Two new species of Esthemopsis C. Felder & R. Felder, 1865 from southeastern and northeastern Brazil are described, Esthemopsis sateri sp. nov. and Esthemopsis diamantina sp. nov., and revised and new combinations are proposed for Esthemopsis teras (Stichel, 1910) stat. rev. and Esthemopsis pallida Lathy, 1932 stat. nov., respectively. Lectotypes are designated for Lepricornis teras Stichel, 1910 and Esthemopsis caerulea pallida Lathy, 1932. The habitus of male and female specimens of the species discussed are illustrated; male head and labial palpus pictures, male and female genitalia illustrations are provided.

A new species of Aricoris Westwood, [1851] belonging to “ chilensis ” group (Lepidoptera: Riodinidae)

A new species of Riodinidae from the grasslands of South Brazil, Paraguay and Argentina, Aricoris schneideri sp. nov., is described.

A NEW SPECIES OF EURYBIA (LEPIDOPTERA: RIODINIDAE: EURYBIINI) FROM NORTHEASTERN BRAZIL

Abstract A new species of Eurybia [Illiger], 1807 (Lepidoptera: Riodinidae: Eurybiini), Eurybia gonzaga sp. nov., is described from the state of Pernambuco, Northeastern Brazil and compared with its closest ally, Eurybia pergaea (Geyer, 1832). Taxonomic comments, illustrations of the adults and male genitalia are provided.

A new species of Cogia from Oaxaca, Mexico (Lepidoptera: Hesperiidae: Eudaminae).

A new species of Cogia A. Butler, 1870, is described from two localities ranging from 1470 to 2000 m elevation in the Sierra Madre del Sur of Oaxaca, Mexico; it occurs in cloud forest habitats and appears to be endemic to Mexico. Cogia buena, n. sp., is closely related to C. mala Evans, 1953 and C. aventinus (Godman & Salvin, 1894); these three species are the only known Cogia taxa whose males lack a hair tuft on the dorsal hindwing, and all have similar genitalia.

Insecta, Lepidoptera, Riodinidae, Nymphiidini, Aricoris terias (Godman, 1903): first records from Brazil and updated geographic distribution map

This paper provides the exact location of the first records from Brazil of Aricoris terias (Godman, 1903) and an updated geographic distributional map of the species, extending the known range of the species over 1300 km. This is also the first record of this species on a wet forest environment.

Hidden in plain sight: a morphological study revealing three new species of the skipper genus Drephalys Watson, 1893 (Lepidoptera: Hesperiidae) from Brazil

Three new species of Drephalys Watson, 1893 from Brazil are described as follows: D. dracarys Madruga, Siewert, Mielke Dolibaina, sp. n. from Acre, Mato Grosso and Rondônia states, D. electrinus Siewert, Madruga, Mielke Dolibaina, sp. n. from Acre and Amazonas states, and D. citrinus Madruga, Siewert, Mielke Casagrande, sp. n. from Amazonas state. Drephalys heraclides Bell, 1942 was reported for the first time from Brazil. To characterize the new species, illustrations of the male genitalia of D. heraclides, D. phoenice (Hewitson, 1867) and D. phoenicoides (Mabille Boullet, 1919) are provided. Diagnosis, adult photos, illustration of the male genitalia and a geographical distribution map are provided for the new species.

A new species of Wahydra from Ecuador (Hesperiidae, Hesperiinae, Anthoptini)

Recent taxonomic studies on the genus Wahydra Steinhauser, 1991, have described five new species in the past two years, from high elevations in the Andes Mountains. A markedly distinct species of Wahydra is herein described and illustrated based on a single male specimen from Ecuadorian Andes, Wahydra graslieae A. Warren, Carneiro Dolibaina, sp. nov. The new species is compared with other species of Wahydra, as well as with the somewhat similar species Lerema viridis (Bell, 1942) and Tigasis viridenex (Weeks, 1901).

Taxonomy of Rufocumbre gen. nov., a new Moncini skipper genus (Lepidoptera: Hesperiidae: Hesperiinae)

Rufocumbre gen. nov. (type species: Rufocumbre celioi sp. nov.), a new genus of Neotropical skippers belonging to the tribe Moncini is described to include five species known only from Brazil. Four new species are described: Rufocumbre celioi sp. nov. from the states of Minas Gerais, Rio de Janeiro, São Paulo, Paraná, Santa Catarina and Rio Grande do Sul; Rufocumbre emeryi sp. nov. from the states of Mato Grosso, Distrito Federal, Goiás and Minas Gerais; Rufocumbre schneideri sp. nov. from the states of Tocantins, Distrito Federal, Minas Gerais and Paraná; and Rufocumbre lucasi sp. nov. from the states of Bahia and Minas Gerais. The taxon Cumbre belli eberti Evans, 1955 is transferred to the new genus and elevated to the species level, Rufocumbre eberti (comb. nov., stat. nov.). Adults, male androconia and genitalia of both sexes are illustrated for all species.

Monotypic no longer: a new species of Panca Evans (Lepidoptera: Hesperiidae: Hesperiinae: Moncini) from South America

A new species belonging to the previously monotypic genus Panca Evans, 1955, P. moseri Dolibaina, Carneiro & O. Mielke sp. nov., from grasslands areas of Peru, Bolivia and Brazil is described. Adults and male and female genitalia of the new species are illustrated, described in detail, and compared with the type species of the genus, Lerodea subpunctuli Hayward, 1934, and with its externally most similar and sympatric species, Vidius mictra Evans, 1955. The systematic position of the genus Panca and its association with lowland open natural habitats of South America are discussed.
