Remarks

The names “ amoenus Dej.” and “ fallax Chevrolat ” appears in the Dejean Catalogue (1836) within the same pair of brackets. Both names were published before 1931 and lack a description or an indication of the taxon they denote. Therefore, they fail to conform to Article 12 of the CODE ( ICZN 1999) and here are considered nomina nuda. The “Lectotipo” label is that used by Alvarenga, and was likely placed on the specimen when he studied it. We accept and validate that designation.
