Gastrotheca excubitor | |
Gastrotheca excubitor is a species of frog in the family Hemiphractidae. It is endemic to southern Peru and occurs in the Amazonian slopes and crests of the Cordillera Oriental in the Cusco Region; records from the Cajamarca Region are likely erroneous. [1] [3] It is likely to include cryptic species. [1] Common name Abra Acanacu marsupial frog has been coined for it. [1] [3]
Adult males measure 21–40 mm (0.8–1.6 in) and adult females 33–41 mm (1.3–1.6 in) in snout–vent length. [2] [4] The snout is rounded. The tympanum is vertically ovoid; the supra-tympanic fold is weakly developed and granular. The fingers have no webbing whereas the toes have basal webbing; the discs are almost round. Skin is smooth dorsally. The dorsum is tan, gray, or green and has dark brown or green markings consisting of a broad inter-orbita1 bar that is connected to pair of broad, longitudinal stripes; the latter are partially or completely merged in some specimens. The flanks are bronze-tan to bluish green and have dark brown and/or cream spots. The venter is tan. The iris is copper with fine black reticulations. The vocal sac in calling males is dark gray. [2]
Females have a single median brood pouch in which the eggs are brooded until they hatch into froglets. The average fecundity is about 20 eggs. [1]
Gastrotheca excubitor is a terrestrial frogs inhabiting humid Puna grassland with mosses and bunchgrass, above the treeline (3,080–4,080 m (10,100–13,390 ft) above sea level). It can also be found in low intensity farmed areas. They are typically found beneath stones during the day, or walking about in deep moss. Males call at night. [1]
This species is threatened by habitat loss caused by agriculture, burning of grasslands, and the development of tourism infrastructure. The fungus Batrachochytrium dendrobatidis has been detected in the species, but it appears resistant to it. Gastrotheca excubitor is known from several protected areas, including the Manú National Park and Machu Picchu Historical Sanctuary. [1]
Gastrotheca is a genus of frogs in the family Hemiphractidae. They are found in Central America south of Costa Rica and in South America. Most species occur in the American Cordillera from southern Costa Rica to north-western Argentina. This genus makes up the bulk of marsupial frog diversity; formerly it was placed in the "Leptodactylidae" assemblage.
Pristimantis ceuthospilus is a species of frogs in the family Craugastoridae. It is endemic to northern Peru and occurs in the western slopes of the Cordillera de Huancabamba and the Pacific slope of the Cordillera Occidental. There are also as yet unconfirmed records from southern Ecuador. The specific name ceuthospilus, from Greek keuthos ("hidden") and spilos ("spot"), refers to the yellow spots in the groin and thighs that remain hidden when the frog is sitting. Common name Wild's robber frog has been coined for it.
Gastrotheca abdita is a species of frog in the family Hemiphractidae. It is endemic to Peru and only known from the Cordillera Colán in the Amazonas Region. The specific name abdita is Latin for "exiled" or "removed" and refers to the geographic isolation of the Cordillera Colán. Common name Cordillera Colan marsupial frog has been coined for it.

Gastrotheca argenteovirens is a species of frog in the family Hemiphractidae. It is endemic to Colombia and occurs in the Colombian Massif, Cordillera Central, and Cordillera Occidental in the Quindío, Tolima, Valle del Cauca, Cauca, and Nariño Departments. Common name Popayan marsupial frog has been coined for it.
Gastrotheca atympana is a species of frog in the family Hemiphractidae. It is endemic to Peru and only known from its type locality in the Pampa Hermosa National Sanctuary, Junín Region. It lacks an external tympanum, hence the specific name atympana.
The horned marsupial frog, originally named Nototrema cornutum Boulenger after the first describer George Albert Boulenger in 1898), is a species of frog in the family Hemiphractidae. It is an arboreal species found in Colombia, Costa Rica, Ecuador and Panama. Its natural habitats are tropical moist lowland forests and montane cloud forests. It is threatened by habitat loss.
Gastrotheca dunni is a species of frog in the family Hemiphractidae. It is endemic to the northern part of the Cordillera Occidental in northern Antioquia, Colombia. The specific name dunni honors Emmett Reid Dunn, an American herpetologist. Common name Dunn's marsupial frog has been coined for it.
Gastrotheca guentheri is a species of frog in the family Hemiphractidae. It is found in the Andes of Colombia and Ecuador. Gastrotheca guentheri is the only known frog with true teeth in both of its jaws, as indicated by the name of the genus it originally typified, Amphignathodon, described by George Albert Boulenger in 1882.
The Helena's marsupial frog is a species of frog in the family Hemiphractidae. It is endemic to the Páramo de Tamá on the Venezuelan-Colombian border and occurs in Apure and Táchira states of Venezuela and Norte de Santander Department on the Cordillera Oriental of Colombia. It is named after Helen Gaige, an American herpetologist.
Gastrotheca nicefori is a species of frog in the family Hemiphractidae. It is found in the Andes of Colombia, on the Andean slopes of northern Venezuela, and in the highlands of eastern and central Panama.
Gastrotheca ochoai is a species of frog in the family Hemiphractidae. It is endemic to southern Peru and occurs in the interandean valleys on the eastern face of the Andes. The specific name ochoai honors Oscar Ochoa Mendieta, a biology professor from the National University of Saint Anthony the Abbot in Cuzco who helped the species descriptors during the field work. Common name Chilca marsupial frog has been coined for this species.
Gastrotheca pacchamama is a species of frog in the family Hemiphractidae. It is endemic to Peru and only known from the Ayacucho Region in the Cordillera Oriental.
The Andean marsupial tree frog, also known as the Riobamba marsupial frog or Riobamba pouched frog, is a species of frog in the family Hemiphractidae. It is endemic to Ecuador. The species is confined to the Andes and the inter-Andean valleys, from Imbabura south to Chimborazo. They live in an altitude of 2,200-3,500 meters above sea-level. The Andean marsupial tree frog's habitat varies from the montane forests to the dry rocky hillsides, and from the agave plants to the corn fields. Once a common species, it is threatened by severe habitat loss.
Gastrotheca splendens is a species of frog in the family Hemiphractidae. It is endemic to Bolivia. The only precisely known record is from the eastern slopes of the Andes in the Amboró National Park, in the Santa Cruz Department. Only two specimens are known. Common name Schmidt's marsupial frog has been coined for this species, in reference to Eduard Oscar Schmidt who described the species.
Gastrotheca stictopleura is a species of frog in the family Hemiphractidae.

Gastrotheca trachyceps is a species of frog in the family Hemiphractidae. It is endemic to the Cauca Department, Colombia, and is known from its type locality, Cerro Munchique in the Cordillera Occidental, and Vereda Santa Elena (Popayán) in the Cordillera Central. The specific name trachyceps is said to be derived from Greek trachy meaning "rough" and Latin ceps meaning head, in reference to the rough appearance of the head. The proper word in Latin for head is however caput. Common name Cerro Munchique marsupial frog has been coined for it.
Gastrotheca zeugocystis is a species of frogs in the family Hemiphractidae. It is endemic to Peru and only known from its type locality on the Cordillera de Carpish, Huánuco Region. The specific name zeugocystis refers to the paired brood pouches in this species.
Stefania breweri, also known as Brewer's carrying frog, is a species of frog in the family Hemiphractidae. It is endemic to Cerro Autana, Venezuela, and only known from a single specimen (holotype). It was named for Venezuelan explorer Charles Brewer-Carías.
The Hemiphractidae are a family of frogs from South and Central America. Previously, this group had been classified as a subfamily (Hemiphractinae) under family Hylidae. More recent research classifies these genera into their own family, or sometimes into three separate families: Amphignathodontidae, Cryptobatrachidae, and Hemiphractidae (Hemiphractus). An active question still exists as to which of these groupings is more accurate.
