In the Plectrohyla guatemalensis group of Faivovich, Haddad, Garcia, Frost, Campbell, and Wheeler, 2005, Bull. Am. Mus. Nat. Hist., 294: 105. Urbina-Cardona and Loyola, 2008, Tropical Conserv.

See illustration, map, description of geographic range and habitat, and conservation status in Stuart, Hoffmann, Chanson, Cox, Berridge, Ramani, and Young, 2008, Threatened Amph. World: 270. Köhler, 2011, Amph. Cent. Am.: 246–255, provided a brief summary of natural history for the species of Plectrohyla in Central America and provided a range map and photograph for this species. González-Martínez, Núñez-Robles, and Ariano-Sánchez, 2021, Rev. Latinoam. Herpetol., 4: 226–227, discussed declining populations and the rediscovery of an adult in 2018 (otherwise last see in 1976) at the crater of Chicabal volcano, San Martín Sacatepéquez, Quetzaltenango, Guatemala.
