The male of Dossenus guapore silva, lise & carico, 2007 is described and illustrated for the first time, based on material from Bonito, Mato Grosso do Sul, Brazil. The spider genus Dossenus simon, 1898 is distributed from Panama to southern Brazil and can be distinguished by the other known genera of Trechaleidae by the median dark brown band on the carapace that extends to the abdomen and by the spoon-like shape of the median apophysis of the male palpus. A new species of Dyrines simon, 1903, D. brescoviti sp. nov., is described and illustrated based on material collected in Sergipe and Paraná, brazil. The representatives of this spider genus are relatively small and can be distinguished from the other genera by the longitudinal dark brown bands on the legs. new records of Dyrines striatipes (Simon, 1898) are presented.
