摘要

Chactas braziliensis Louren?o, Aguiar & Franklin 2005 was described on the basis of four adult females collected in the state of Amazonas, Brazil, and represents the only species of this genus in the country.In this paper, the male of this species, which has never been recorded, is described for the first time by using a specimen taken from the state of Acre, Brazil. Males of C. braziliensis can be distinguished from those of other small (up to 35 mm) Chactas species (C. adornelae Rossi 2014 and C. koepckei Louren?o & Dastych 2001) by the numbers of pedipab femur carinae and pectinal teeth.
