The specific name is patronymic in honor of John Winston Lennon (1940-1980), the legendary creator of The Beatles, who contributed to make this world a gentler place.

Natural history.

All specimens from Estação Científica Ferreira Penna, FLONA Caxiuanã were collected in pit-fall traps used for herpetological surveys or in nocturnal manual searching, in both flooded and dry areas.
