Abstract

Two new species of Pamphobeteus Pocock 1901 are described from Brazil: Pamphobeteus crassifemur sp. nov. and Pamphobeteus grandis sp. nov.; Pamphobeteus nigricolor, formerly described from Colombia, Ecuador and Bolivia, is recorded from Brazil and its distribution in Ecuador and Bolivia is questioned. A new type of stridulatory organ is described from legs III and IV of P. crassifemur sp. nov. The structure consists of spiniform setae. Stridulation occurs when the spider moves the legs III and IV, sometimes while shedding urticating hairs.
