Remarks:
Although recorded from Peru (Meede 1984), the species is not found in the country (Podloucky 1987).
Although reported from Sao Paulo, the species does not occur in the state.
Records from Sao Paulo were based on misinterpretation of a locality which is actually in the state of Rio de Janeiro (Garbin, Karlguth, Fernandes & Pinto 2016).
Records from Mato Grosso (e.g., Rhodin, Silva & Mittermeier 1984; Iverson 1992) were probably based on mislabelled specimens.
The species is not considered present in the state (Garbin, Karlguth, Fernandes & Pinto 2016).
Presence in Amazonas (as reported by Wermuth & Mertens 1977) is also regarded as erroneous (Garbin, Karlguth, Fernandes & Pinto 2016, by implication).
Distribution:
Brazil
(Alagoas,
Bahia,
Espirito Santo,
Minas Gerais,
Rio de Janeiro,
Sergipe).
