ABSTRACT
ABSTRACT COVID-19 (coronavirus disease 2019) is an infectious disease caused by the new coronavirus associated with severe acute respiratory syndrome 2 (SARS-CoV-2). Coronaviridae comprises a large family, of which at least seven members are known to cause respiratory diseases in humans. Coronaviruses have the ability to infect virtually all major groups of animals and, eventually, can infect humans. SARS-CoV-2 is the third coronavirus to cross the species barrier and infect humans. This virus was identified in an outbreak of pneumonia cases in Wuhan city, Hubei province, China, in December 2019. Its entire genome is inscribed on a single strand of ribonucleic acid. Some proteins present on the surface of the virus act as facilitators for its entry into host cells, while others, apparently, are related to its pathogenesis. Coronaviruses are responsible for respiratory infections in humans and some animals. The infection is often mild to moderate in intensity, but some coronaviruses may cause serious illnesses, such as severe acute respiratory syndrome (SARS), which occurred in 2002, and the Middle East respiratory syndrome (MERS). Coronaviruses can activate an excessive and unregulated immune response, which may promote SARS development. Although the lungs are one of the target organs, the hypoxia mechanism is systemic and other organs begin to suffer both through lack of oxygen and through deregulation of inflammation control mechanisms.

This paper describes a new species of Moneuptychia Forster from the cerrado in the Federal District and Goiás region in central Brazil, and from highland open vegetation (campos de altitude) of Minas Gerais and Paraná. We provide details of the adult morphology and discuss the new species placement in the genus Moneuptychia.

Neste estudo é apresentada uma listagem atualizada com 335 espécies de borboletas Hesperiidae encontradas no Distrito Federal (Brasil central), incluindo dados da bibliografia, de várias coleções entomológicas e de coletas dos autores. Espécies de ocorrência apenas presumida não foram incluídas. Apresenta-se também uma lista suplementar com 32 espécies endêmicas do bioma Cerrado, das quais 27 foram encontradas no Distrito Federal.
An updated list containing 335 species of skippers (Hesperiidae) found in the Distrito Federal (central Brazil), including data obtained from the literature, from several entomological collections, and from collecting of the authors, is presented. Species with presumed distribution in the region are not included. It is presented too, a supplementary list with 32 endemic species occuring in the Cerrado vegetation, from which 27 were found in the Distrito Federal.

Uma listagem atualizada com 507 espécies de borboletas (Papilionoidea e Hesperioidea) encontradas na APA do Gama e Cabeça de Veado - DF nas últimas quatro décadas é apresentada neste estudo. Foram reunidos dados da bibliografia, de nossas coletas pessoais e coleções entomológicas, mas espécies com ocorrência apenas presumida não foram incluídas. Nossos objetivos com esta publicação são: (1) demonstrar a importância desta APA para a conservação da fauna de borboletas do cerrado e (2) permitir o monitoramento futuro da biodiversidade deste grupo de insetos nestes locais.
A list containing 507 species of butterflies (Papilionoidea e Hesperioidea) found in the APA do Gama e Cabeça de Veado - DF in the last four decades is presented in this study. The list includes data obtained in the literature, our personal collections, and entomological collections recently visited, but not species with presumed distribution in the region. The purpose of this study is (1) to demonstrate the importance of this APA for the conservation of the cerrado butterfly fauna and, (2) allow for monitoring such biodiversity in future studies.
