Costanana DeLong & Freytag, 1972 is a Neotropical genus of leafhoppers currently comprising 13 species with a wide distribution from Mexico to Argentina. In this study, eight new species of Costanana are described, C. xenomorpha sp. nov. from Department of Cuzco, Peru, and seven Brazilian species: C. alata sp. nov. from Minas Gerais State; C. bifida sp. nov. from Paraná and Mato Grosso states; C. cifi sp. nov., C. obtusa sp. nov. and C. piraquarensis from Paraná State; C. luzi sp. nov. from Distrito Federal; and C. rubromarginata sp. nov. from Mato Grosso and Pará states. We propose that Costanana cella DeLong & Freytag, 1972 is a junior synonym of C. praecellens (Stål, 1862) and C. asymmetrica DeLong & Freytag, 1972 is a junior synonym of Gypona viridans DeLong & Martinson, 1972. Costanana costata DeLong & Freytag, 1972 and C. flavicosta (Stål, 1862) are transferred to Gypona Germar, 1821, C. minuta (Spångberg, 1878) is transferred to Acuponana DeLong & Freytag, 1970 and Gypona nupera Van Duzee, 1907 is transferred to Costanana. Gypona costata comb. nov. and Costanana santana DeLong & Wolda, 1983 are newly recorded from Pernambuco State, and Gypona flavicosta comb. nov. is recorded from Espírito Santo and Paraná states, Brazil. The female genitalia of Costanana flavina DeLong & Freytag, 1972, C. praecellens and Gypona flavicosta comb. nov. are described and illustrated for the first time and a brief note on feeding behavior is given for C. flavina and C. praecellens. A key to males and a new diagnosis are provided for Costanana. We also describe and illustrate Metacostana cornuta gen. et sp. nov., a new Brazilian genus for Gyponini sharing characteristics with Costanana, Acuthana Domahovski & Cavichioli, 2018, Domahovana Silva et al., 2022 and Dumorpha DeLong & Freytag, 1975.
This paper considers ways in which rulers can respond to, generate, or exploit fear of COVID-19 infection for various ends, and in particular distinguishes between ‘fear-invoking’ and ‘fear-minimising’ strategies. It examines historical precedent for executive overreach in crises and then moves on to look in more detail at some specific areas where fear is being mobilised or generated: in ways that lead to the suspension of civil liberties; that foster discrimination against minorities; and that boost the personality cult of leaders and limit criticism or competition. Finally, in the Appendix, we present empirical work, based on the results of an original survey in Brazil, that provides support for the conjectures in the previous sections. While it is too early to tell what the longer-term outcomes of the changes we note will be, our purpose here is simply to identify some warning signs that threaten the key institutions and values of democracy.
Habenaria karstica J.A.N.Bat. sp. nov., a new species from limestone outcrops (i.e., karst) in the State of Minas Gerais, Brazil, is described. The new species is ecologically very distinct since it is the only Neotropical species of the genus that grows on limestone outcrops under full sun, associated with mat-forming saxicolous plants. It is morphologically similar to species of the Habenaria repens complex, and separation is only possible through a combination of morphological characters. Bayesian and parsimony phylogenetic analyses based on nuclear (rDNA ITS, ETS) and plastid (matK-trnK, rps16-trnK) DNA markers revealed that H. karstica belongs to H. sect. Spathaceae. The new species, however, differs in floral morphology from the other species in this clade. A survey of the literature and public plants datasets revealed 122 species and 58 genera of Orchidaceae in karsts of Brazil. Although small compared to the family’s diversity in the country, Orchidaceae is among the families with the highest number of species in some karst localities. Our results indicate that approximately 97% of Orchidaceae found in karsts of Brazil is not limited to limestone outcrops areas, and that species composition of each locality is primarily determined by the regional flora and the biome in which it is located.
The genus Cyparium Erichson, 1845 (Staphylinidae, Scaphidiinae, Cypariini) comprises 55 species, distributed mainly in the Neotropical and Oriental regions. Twenty-four species are known from the Neotropical region, but only eight species are reported from Brazil. In this paper we describe five new species and redescribe two species of Brazilian Cyparium, as follows: Cyparium achardi sp. nov., C. lescheni sp. nov., C. loebli sp. nov., C. newtoni sp. nov., C. pici sp. nov.; Cyparium collare Pic, 1920; and Cyparium oberthueri Pic, 1956. We provide images of adult males and females and their dissected parts, and information on host fungi whenever available. We also provide a comparative plate of dorsal colour patterns of Neotropical Cyparium.
The genus Oplognathus MacLeay, 1819 is revised based on type material of two of the three described species and scattered additional material from several collections around the world. The diagnostic characters of the genus are confirmed, distinguishing it from other Brazilian Areodina mainly by: quadrangular clypeus with trilobate apex in males, rounded in females, extending beyond labrum in both sexes; mandibles with three distinct teeth; maxillae with six teeth; antenna with 10 antennomeres; 10 elytral striae; mesoventral process present; and asymmetrical parameres. The genus and all three species are redescribed, and the female of Oplognathus bahianus Ohaus, 1912 is described for the first time. We consider Oplognathus helmenreichi var. maculicollis Ohaus, 1914 an unavailable infrasubspecific taxon that is conspecific with Oplognathus helmenreichi Ohaus, 1905; its distribution is updated, and the different spelling of the specific epithet is discussed. A neotype is designated for Oplognathus kirbii MacLeay, 1819 since the holotype is currently considered lost. Additionally, an identification key and a distribution map are included.
Der vorliegende Artikel nimmt die stetig zunehmende Nutzung von Online-Medien im Fremdsprachenunterricht zum Anlass, um anhand eines konkreten Beispiels die Heraus-forderungen und Möglichkeiten des Blended Learning (BL) zu umreißen. Grundlage der Überlegungen ist das Sprachlernprogramm "Idiomas sem Fronteiras" ("Sprachen ohne Grenzen"), über das seit 2016 Online-Deutschkurse mit tutorieller (Präsenz-)Begleitung an brasilianischen Hochschulen angeboten werden. Eine Umfrage unter 228 Teilnehmenden eines Kursdurchlaufs im Jahr 2019 an brasilianischen Universitäten liefert empirisch belegbare Ergebnisse zum BL-Setting, die analysiert werden und in Überlegungen zur didaktischen Umsetzung münden.
Three new species of Eusarcus Perty, 1833 are described from Brazilian caves, increasing the number of species of the genus to 40, eight of which have occurrences in caves. Eusarcus capixaba sp. nov. is described from Lapa do Sítio Paraíso Cave, municipality of Ecoporanga, state of Espírito Santo. Eusarcus marmoreus sp. nov. is described from Caverna Archimides Panssini Cave, municipality of Vargem Alta, state of Espírito Santo. Finally, Eusarcus xambioa sp. nov. is described from Caverna da Explosão Cave, municipality of Xambioá, state of Tocantins. Notes on the species’ habitats and a distribution map are also provided.
Taxonomic review of the genus Erythrocricus Schubart, 1962 (Diplopoda, Spirobolida, Rhinocricidae)
(2021)
We review the genus Erythrocricus Schubart, 1962 based on the type material of the species Erythrocricus sanguineostriatus (Schubart, 1962). We propose a new diagnosis, redescribe the type species, and propose a new synonymy and a new combination. In addition, a male-based key to both species recognized, including Erythrocricus electrofasciatus (Schubart, 1957), comb. nov. ex. Rhinocricus, is given.
Fractipes tayrona new species (Coleoptera: Chrysomelidae: Eumolpinae: Eumolpini) is described from a dry forest on the Caribbean coast of Colombia. This locality is very distant from the localities in southeast Brazil, where the other two known species of Fractipes Bechynĕ were described. Male and female genitalia are described for the first time in this genus, and F. tayrona is compared with holotype photographs of F. rhabdopteroides Bechynĕ and F. secundus Bechynĕ and Springlová de Bechynĕ.
