Craugastor sabrinus, also known as the long-legged streamfrog, is a species of frog in the family Craugastoridae. [1] [2] It is found in Belize and eastern Guatemala. [1] [2] The specific name sabrinus is derived from the Latin sabrina, meaning "river nymph", and alludes to the stream-side habitat of this species. [3]

Description

Adult males measure 38–44 mm (1.5–1.7 in) and adult females 69–83 mm (2.7–3.3 in) in snout–vent length. The canthus rostralis is moderately sharp. The tympanum is distinct. Dorsal skin is smooth–granulate, with few scattered tubercles and weak parietal and supra-scapular ridges. The finger and toe discs are moderately developed, up to 1.5 times the digit width. The fingers and the toes have well-developed lateral keels or narrow flanges; the toes are moderately webbed. The dorsum is dark olive-brown, reddish brown, or tan. A yellow, orange, or tan vertebral line or stripe is sometimes present. A dark brown interorbital is present but is often ill-defined. The larger tubercles or folds are often tan or pale brown, with black edges. Limbs have darker brown bars that are not too conspicuous. The flanks are lighter. Males have whitish throat with dark mottling; the chest is whitish, grading to yellow on the belly. Females have less yellow on the belly. [3]

Habitat and conservation

Craugastor sabrinus occurs in lowland and premontane wet and moist forests at elevations up to 900 m (3,000 ft) above sea level. It lives in and alongside pristine streams and does not occur in degraded forests, although it can be found in areas that have been farmed in the past. The eggs are laid on land and the development is direct (i.e., no free-living larval stage). [1]

This species has declined in Guatemala but is still common in Belize. It is threatened by habitat loss, which is principally caused by agricultural development, but also by logging, hydroelectric development, oil and mineral extraction, and expanding human population. It occurs in a number of protected areas. [1]

It is endemic to eastern Guatemala and is only known from three localities in the Sierra de las Minas and Montañas del Mico ranges. The specific name panchoi honors Laurence Cooper "Don Pancho" Stuart, an American herpetologist.

Craugastor adamastus is a species of frog in the family Craugastoridae. It is endemic to Guatemala and only known from its type locality near Aldea Vista Hermosa, on the northern slopes of the eastern portion of the Sierra de las Minas, where the type series was collected in 1980–1981.

Craugastor amniscola is a species of frogs in the family Craugastoridae. It is found in western Guatemala and in Chiapas, Mexico. The specific name amniscola is derived from Latin amnis for rivulet and -cola for dweller and refers to the habitat of this species. Accordingly, common name rivulet rainfrog has been coined for it.

Craugastor andi is a species of rain frog in the family Craugastoridae which has not been seen since 1990. It is found in the Caribbean drainage of Costa Rica in the mountains and hills of the Cordillera Central and the far northeastern Cordillera de Talamanca, and in extreme northwestern Panama. Frank and Ramus (1995) give it the vernacular name Atlantic robber frog. It is known locally in Spanish by the generic names, used for many species, of rana de hojarasca, ranita or sapito.

Craugastor catalinae is a species of frogs in the family Craugastoridae. It is found in the Río Cotón drainage in the Pacific southwestern Costa Rica and on the Pacific slopes of Volcán Barú, western Panama. The specific name catalinae, rather obliquely, honors Karen R. Lips: Spanish name "Catalina" corresponds to Danish name "Karen". Lips collected a part of the type series and has "contributed substantially to our knowledge of the Río Cotón drainage herpetofauna and the declining amphibian populations problem in lower Central America."

<i>Craugastor chrysozetetes</i> Extinct species of amphibian

Craugastor chrysozetetes is a possibly extinct species of frog in the family Craugastoridae. It is endemic to Honduras where it is only known from near its type locality on the Cerro Búfalo, Cordillera de Nombre de Dios, at the edge of the Pico Bonito National Park. Common name McCranie's robber frog has been coined for this species. However, James McCranie himself has argued that this name "should be rejected in favor of a name associated with the type locality instead of a name tied to one of the three authors who named this species".
