The Hesperiidae (Lepidoptera, Hesperioidea) from RPPN Klagesi, Santo Antonio do Tauá, Pará, Brazil: a new contribution to biodiversity's knowledge of Belém endemism area

The region of Belem is one of the best known area of the Amazon Forest, given its scientific explorations since the 18 super(th) century. However much of the informations about the biological diversity of the region is scattered at several museums around the world, thus making it harder to access and to propose biogeographical hypothesis.. Aiming to contribute to the knowledge of lepidopterological diversity of the region, the present study lists 225 species of Hesperiidae present at Private Natural Reserve Klagesi registered during approximately 24 years of sporadically collecting, although more frequently on the past decade. One hundred and thirteen species not yet registered in endemism's region of Belem are added, which makes it the richest of all Amazonian endemism areas in Brazil. However, the Amazonian skippers are so poorly known that this richness index can only be used for effort comparisons instead of biogeographical or ecological inferences. Three of the endemism regions still lack information about their diversity (Xingu, Napo and Imeri), while others are known basically from one or a few inventories. Therefore, focused sampling at those unknown areas or gathering information at international museums are indispensable strategies to obtain a better knowledge of Amazonian butterfly diversity so they can be used for biogeographical studies and conservation management.Original Abstract: Embora a regiao Belem seja uma das areas mais exploradas da Amazonia com coletas desde o seculo XVIII, grande parte das informacoes se encontra dispersa era colecoes internacionais, o que dificulta a reuniao de dados e interpretacoes biogeograficas. Visando ampliar o conhecimento da fauna de lepidopteros da regiao, o presente estudo levantou uma lista de 225 especies de Hesperiidae encontradas na RPPN Klagesi durante aproximadamente 24 anos de amostragens esporadicas, embora mais frequentemente na ultima decada. Sao adicionadas 113 especies previamente nao relacionadas para a regiao, a qual passa a ser a area de maior riqueza conhecida de Hesperiidae dentre todas as regioes de endemismo da Amazonia brasileira ate entao inventariadas. No entanto, o conhecimento da diversidade de Hesperiidae em outras areas de endemismo e tao restrito, que a riqueza de especies deve ser utilizada apenas como indicador de esforco amostral ao inves de inferencias biogeograficas. Tres das regioes de endemismo ainda nao apresentam nenhum inventario de fauna (Xingu, Napo e Imeri), enquant
