Description

Ikakogi tayrona can be identified by the following combination of characters: 1) vomerine dentition absent, 2) bones white in life, 3) color in life green to pale green, 4) snout rounded when viewed dorsally, sloped and truncated when viewed laterally, 5) skin is dorsally granular, 6) ulnar and tarsal folds small, 7) males have a large humeral spine.

Adult females reach 28.2-30.8mm SVL, males reach 28.2-30.6mm SVL. Head as wide as body, but wider than long (head width 34.8-38.7 % SVL). Nostril-eye distance is 52.8-83.9 % eye width. Nostrils protuberant and oriented anterolaterally. Eyes not visible around border of snout when viewed ventrally. Supratympanic fold thick and very well defined. Vomerine dentition absent. Length of tibia is 51.9-58.6 % SVL.

Distribution and Habitat

Country distribution from AmphibiaWeb's database: Colombia

View distribution map in BerkeleyMapper.

This species is known only from the northern part of the Sierra Nevada de Santa Marta, department of Magdalena, county of Santa Marta in Colombia from 980-1790 m in elevation. They have been collected on vegetation approximately 2-3 m above the ground bordering breaks in the forest.

Life History, Abundance, Activity, and Special Behaviors
In 2016, Valencia and Delia (2016) reported parental care in Ikakogi tayrona, the geographically (Sierra Nevada de Santa Marta, Colombia) and phylogenetically isolated sister-taxon of all other centrolenids. Unexpectedly, the parental care is by females. Care functions are similar in both males and females, but females are somewhat more risk-tolerant, probably reflecting the more direct link to fitness in females (Valencia and Delia 2016).
