We think that this record does not match with the habitat of the species. The department of Lima belongs to the Desert province as defined by Morrone (2014 , 2015 ) and the species has as inhabits tropical forests ( Caron et al . 2012 ). Others specimens were collected in Peru (Loreto, Huánuco, Junín, Ucayali and Cuzco) in tropical forests. Madre de Dios is a new department record. The species was previously known from Cayenne in French Guiana.
