Amazon Milk Frog (Trade name).

Blue Milk Frog (Trade name).

Kunawalu Casque-headed Frog (Kok and Kalamandeen, 2008, Intr. Taxon. Amph. Kaieteur Natl. Park: 210).


Eastern part of the Amazon Basin in Brazil and north into the Guianas; the status of populations (whether Trachycephalus cunauaru or Trachycephalus resinifictrix) of Venezuela remains unanswered. 


Recognized as distinct from Phrynohyas venulosa by Lescure, 1976, Bull. Mus. Natl. Hist. Nat. Paris, Ser. 3, Zool., 377: 503, in which synonymy it had been placed by Duellman, 1956, Misc. Publ. Mus. Zool. Univ. Michigan, 96: 35 Rodríguez and Duellman, 1994, Univ. Kansas Mus. Nat. Hist. Spec. Publ., 22: 42, provided a brief account for the Iquitos region of northeastern Peru as Phrynohyas resinifictrix. Lescure and Marty, 2000, Collect. Patrimoines Nat., Paris, 45: 196–197, provided a photo and brief account for French Guiana. See comments regarding distribution of Venezuelan population by Gorzula and Señaris, 1999 "1998", Scient. Guaianae, 8: 38-39. Kok and Kalamandeen, 2008, Intr. Taxon. Amph. Kaieteur Natl. Park: 210-211, provided an account. See account for Surinam population by Ouboter and Jairam, 2012, Amph. Suriname: 196-199. See Cole, Townsend, Reynolds, MacCulloch, and Lathrop, 2013, Proc. Biol. Soc. Washington, 125: 419, for brief account and records for Guyana. Gordo, Toledo, Suárez, Kawashita-Ribeiro, Ávila, Morais, and Nunes, 2013, Herpetologica, 69: 468, referred specimens from the southern, eastern and central part of the range to Trachycephalus cunauaru. These authors suggested (and provided a map) that Trachycephalus resinifictrix sensu stricto is restricted to the eastern part of the Amazon basin and north into the Guianas. The range for Venezuela is arguable.
