Description
provided by AmphibiaWeb articles
Diagnosis: Small uniformly green frog that can be distinguished by a free prepollex at the base of the thumb with an exposed spine in adult males, a round to truncate snout in profile, dark green bones, and only the parietal peritoneal sheath and heart white (Savage 2002).Description: This rarely seen small frog has a snout vent length ranging from 17.8 mm to 20 mm in adult males and 20 mm to 23 mm in adult females. The head is as wide as long and appears truncated in profile and semicircular in outline. The eyes are large and protuberant, and the interorbital space between is larger than the diameter of the eyes. The snout has a subovoid outline and appears truncated. The tympanum is indistinct and is directed obliquely upward. Vomerine teeth are present in two small patches that are widely separated and immediately medial to the choanae. The body shape is small and slender. The dorsal skin is granular in texture. Finger and toe discs are truncated. Fingers have small subarticular tubercles but no supernumerary tubercles. Accessory palmar and plantar tubercles are present. Finger I is longer than Finger II; vestigial webbing is present between these two fingers. More substantial webbing exists between the outer fingers in the pattern II 2-3 III 2 - 1 3/4 IV. Toes are moderately webbed, described as I 1-2 II 1-2 III 1-2 IV 2-1 V. An elongated inner metatarsal tubercle is present, but the outer metatarsal tubercle is lacking. No inner tarsal fold. Males possess a white nuptial pad on the lateral margin and dorsal of the thumb base. Frogs of this species possess a free prepollex. In larger males the prepollical spine projects externally (Savage 2002). The coloration is uniformly green on the dorsum, with white pigmentation on the undersides of limbs. The iris is gray-ivory with a black reticulum. This species has dark green bones and a white heart (Savage 2002).This species was first described by Taylor (1949).A Spanish-language species account can be found at the website of Instituto Nacional de Biodiversidad (INBio) (http://darnis.inbio.ac.cr/FMPro?-DB=UBIpub.fp3&-lay=WebAll&-Format=/ubi/detail.html&-Op=bw&id=4385&-Find).

Distribution and Habitat
provided by AmphibiaWeb articles
Honduras (McCranie and Wilson 2002; McCranie 2007), Nicaragua (Sunyer and Köhler 2007; Sunyer et al. 2009), Costa Rica (Savage 2002; Kubicki 2007), Panama (Savage 2002), Colombia (Ruiz-Carranza et al. 1996), Ecuador (Cisneros-Heredia and McDiarmid 2005; Cisneros-Heredia and McDiarmid 2007; Cisneros-Heredia 2009). Teratohyla spinosa is distributed in the humid Atlantic lowlands and wet forests ranging from Costa Rica to eastern Panama and south along the Pacific versant to western Ecuador (Savage 2002). It has been found at up to 650 m asl in Costa Rica and 800 m asl in Panama (Coloma et al. 2008).

Throughout the wet season lasting from May to October, males call from the low vegetation surrounding small streams (Savage 2002). The voice of Teratohyla spinosa is similar to that of Cochranella euknemos and Cochranella granulosa : a harsh series of repeating "creep, creeps" with considerable pauses in between (Savage 2002). The dominant frequency is 6.8 to 7.2 kHz (Ibañez et al. 1999). Teratohyla spinosa females lay 18-25 green eggs on the underside of vegetation in a single layer of loose jelly. The eggs and capsules together are 5 to 7 mm in diameter. While embryos appear gray upon hatching, they develop light brown upper-sides and paler under-sides in later stages. Juvenile frogs are 16 mm in standard length when first metamorphosed (Savage 2002).
Life History, Abundance, Activity, and Special Behaviors
provided by AmphibiaWeb articles
This species is common in Costa Rica, Panama, and Colombia, and there are a number of recent reports from Nicaragua. It is not common in either Honduras or Ecuador. The population trend appears to be decreasing. Major threats include habitat loss due to deforestation for agriculture, logging, and human settlement, and pollution from spraying illegal crops. It is found in a number of protected areas, although not in Ecuador (Coloma et al. 2008).
