MORELET’S LEAF FROG
Agalychnis moreletii – Dumeril 1853

IDENTIFICATION:

DISTRIBUTION:
Historically, Agalychnis moreletii is found in several widely-disjunct regions of southern Mexico; In Puebla it is known from the Sierra Norte, in Veracruz from Cuautlapan and the Los Tuxtlas region, in Oaxaca from the Sierra Juarez and Sierra Miahuatlan, from Chiapas in the Sierra Madre de Chiapas and Tapilula/Pueblo Nuevo Solistahuacan, and in the Sierra Madre del Sur of Guerrero. Elevational distribution from 300-1500 m.

HABITAT:

Tropical Montane Habitat, 4,500′, Oaxaca, Mexico

Man-Made Oviposition Site, 4,500′, Oaxaca, Mexico

NATURAL HISTORY:

TAXONOMY:

TYPE:
Described as Hyla moreletii by Dumeril (1853). Syntypes: MNHNP 428. Type locality: “Vera-Paz”, Guatemala; corrected to “Coban in [Departamento Alta] Vera Paz, Guatemala” by Kellogg (1932).

PERSONAL NOTES:
On the night of July 8, 2005 I had the good fortune to discover this species calling from around an old well near Vista Hermosa, Sierra Juarez, Oaxaca. Three males were giving half-hearted vocalizations while perched on cattails about 3-4′ above the water. One Smilisca cyanosticta was also calling from a floating position in the well. On a forested slope nearby, what I believe to be Anotheca spinosa called sporadically. There was no rain on this evening.
Also of note was the fact that the well was full of nearly transformed, as well as 50% grown Agalychnis tadpoles. This indicates that A. moreleti has a lengthy breeding season.

CONSERVATION STATUS:
IUCN Red List status for this species is “Critically Endangered” due to a projected population decline of 80% over the next ten years due to habitat loss and infection with the Chytrid fungus; surveyors in the states of Guerrero, Oaxaca and Chiapas, Mexico reported this species extirpated from all sites they visited. (In July, 2005 I found an extant breeding population in the Sierra Juarez of Oaxaca – photographed above).

My only experience with this frog is with a possible mangled individual I found on the highway south of Lago de Catemaco, Sierra de los Tuxtlas, Veracruz in June, 2005. Many species of Anura were heard calling from adjacent fields but among them were no Agalychnis.
