Description
Diagnosis: Small green frog with yellow spots. Extensive webbing between Finger II and Finger III. Snout tip is indented when viewed from above; in lateral view the snout is rounded to truncate. Liver and digestive tract are white. Pericardium is clear (Savage 2002).

Description: Adult males measure 24-26 mm in SVL. Head broader than long. Truncated and indented snout when viewed from above, but rounded in profile. Nasal area swollen; nostrils open in fleshy protuberances and lie on distinct raised ridges. Tympanum is indistinct. Subarticular tubercles are small and rounded. Finger I is longer than Finger II. Webbing is present, especially between Fingers II and III. Both finger and toe discs are truncated. Inner metatarsal tubercle is elongated while the outer metatarsal tubercle is absent. No tarsal fold. Adult males have a white nuptial pad of scattered glands on dorsal and outer surface of the base of the thumb. Skin on dorsal surfaces is shagreened (Savage 2002).

Dorsal coloration is green with yellow spots. The venter is transparent. Clear pericardium. White liver and digestive tract. Golden iris (Savage 2002).

Hyalinobatrachium chirripoi occurs in the lowlands of southeastern Costa Rica (Kubicki 2004), Honduras (eastern Olancho and eastern Colón, McCranie 2007, as H. cardiacalyptum), eastern Panama (Ibañez et al. 2000), and western Colombia (Jarado and Bahiasolano, in Choco Department, Ruiz-Carranza et al. 1996) . It is found in lowland moist forests at altitudes of 0-700 m asl, in bushes and trees along forest streams (Solís et al. 2004; Frost 2010).

Life History, Abundance, Activity, and Special Behaviors
Adult females lay eggs on the underside of smooth-leaved plants that hang over streams. Males call from below palm leaves 1-4 m above water. The call is an insect-like high-pitched buzz (Kubicki 2004).

Trends and Threats
Although Savage (2002) considered this a rare species, it appears to be common in Costa Rica and stable in population numbers (Solís et al. 2004). In Costa Rica, there appear to be no threats to this species, due to the fact that it appears to tolerate disturbed habitats well (Solís et al. 2004). Some populations in Panama and Colombia are threatened by habitat loss due to increasing agricultural cultivation and logging (Solís et al. 2004).

Possible reasons for amphibian decline

General habitat alteration and loss
Habitat modification from deforestation, or logging related activities
Intensified agriculture or grazing

Comments

This species was first described by Taylor (1958). Cisneros-Heredia and McDiarmid (2007) synonymized H. cardiacalyptum with H. chirripoi.

A Spanish-language species account can be found at the website of Instituto Nacional de Biodiversidad (INBio).
