Ampliação do acervo e identificação de aranhas da família Salticidae da coleção araneológica do Museu Paraense Emílio Goeldi

Abstract

The family Salticidae is the largest 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 Platnick (1989, 1993, 1997), 675 species have been recorded 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 collection of spiders of the family Salticidae of the Museu Paraense Emilio Goeldi, expanding and organizing the collection. Adult individuals captured during collection expeditions or already belonging to MPEG's spider collection are identified to the most precise taxon possible and registered according to the curatorial norms. The literature search resulted in 60 relevant articles, which allowed the identification of 8 genera (Fluda, Chira, Cotinusa, Thiodina, Kalcerrytus, Synemosyna, Capidava, and Noegus). In addition, a taxonomic complex involving the genera Acragas, Amycus, Encolpius, Hypaeus and Mago has also been recognized. To date, over 200 specimens have been examined, 78 of which have been identified to the genus level. Two of the identified species, Capidaoa biuncata Simon and Noegus arator Simon, are currently known only from males. During the course of this work, females of these species were recognized by analyzing the morphological characteristics of the specimens. These associations are corroborated by the fact that individuals of both sexes were collected at the same sampling events. It is planned to soon produce a paper for publication with the description of the female of C. biuncata
