Remarks

According to Lacordaire (1842: 167), in his description of M. psittacus , individuals available to him belonged to the “Collections de M. Dupont et de M. le marquis de Brème”. We chose the specimen from the Brême collection (MRSN) as the lectotype and considered the Dupont specimen (MNHN) as a paralectotype. Gorham (1888) stated that he had not examined any specimen of M. psittacus from Mexico, and suggested that the correct locality for M. psittacus would be “perhaps Bahia ” (Gorham commentary is based on a specimen from the Crotch collection, the same examined by us, see above). Alvarenga (1994) also pointed out that the type locality mentioned by Lacordaire might be wrong and mentioned that M. psittacus occurs in Southeast Brazil. We cannot confirm the exact distribution of M. psittacus in Brazil, although it is possible that this species occurs in the Northeast and Southeast regions.
