Ampliação do acervo e identificação das aranhas da família Salticidae da coleção araneológica do Museu Paraense Emílio Goeldi, com ênfase nos gêneros Capidava e Lyssomanes

Abstract

Spiders, classified in the order Araneae, belong to the class Arachnida and the phylum Arthropoda. They are predatory arachnids that play a key role in population control of other animals, mainly insects. The Salticidae are morphologically homogeneous spiders and are difficult to identify at the genus and species level. Popularly known as "meirinhos" or "papa-moscas, silo characterized by having an ocular formula 4-2-2 or 2-2-2, being the anterior middle eyes very developed, which gives these spiders a great visual capacity. It is the largest family in number of species of the Order Araneae, reaching more than 4000 described species. According to the catalogs of ROEWER (1942, 1954), BRIGNOLI (1983) and PIATNICK (1989, 1993, 1997,2002), 675 species have been registered in Brazil. In the Amazon region, there are more than 250 described species, distributed in approximately 100 genera (BRESCOVIT et al., in press). This work aims to qualify the sampling of spiders of the family Salticidae in the MPEG collection, to continue the training in taxonomic and systematic procedures, to complete the survey of species of Salticidae occurring in the Brazilian Amazon, and to describe the female of Capidava bíuncata, both aiming at the publication of a scientific paper. The method of identification of the spiders consists of analyzing and comparing the genitalia with the primary literature and identifying the taxa as precisely as possible. So far, it has been possible to safely identify the following genera Lyssomanes, Kalcerrytus, Capidava, Fluda, Chira, Cotinusa, Thiodina, Synemosyna, Acragas, Mago and Hypaeus and the taxonomic complex involving the genera Amycus and Encolpius. In addition, the catalog of Amazonian Salticids is practically complete, with 264 records of Salticidae for the Brazilian Amazon.
