Geographic distribution. Brazil (Rondônia, Amazonas, Pará, Bahia) ( BECHYNÉ & BECHYNÉ, 1969). Because of the lack of information on the labels of the specimens from Bahia (all four are pinned together) and to the origin of the specimens being outside the geographical area previously reported, the record of occurrence to the state of Bahia is considered dubious .
