Type material. Holotype: Male from Ilha de Maracá, Rio Uraricuera, Roraima, Brazil, 24.III.1987, A.A. Lise, deposited in INPA 59. Paratype: Female with the same data (INPA 55).

Additional material examined. FRENCH GUIANA: 1m, 4.IV.1999, G.B. Edwards (FSCA); BRAZIL: Amazonas: Manaus: Fazenda Esteio, 1f (INPA 56); BOLIVIA: Beni: Ballivian: San Borja, 1m, 27.VII.1993 (SMNK 1265); Santa Cruz: 1m, 1f, 1–17.III.2003, B.K. Dozier (FSCA).

Etymology. The specific name is a combination, in the South American native language Tupi, between the noun “akypuera” (posterior part) and the adjective “una” (black).

Diagnosis. Breda akypueruna sp. nov. differs from the other species of the genus by having the distal abdominal extremity very dark in both sexes ( Fig. 42 ) and by having the tibial apophysis very developed in the male palp, reaching the distal border of the tegulum ( Fig. 44 ).
