Ikakogi ispacue is a species of amphibian in the Centrolenidae family, which can only be found in the northern Sierra Nevada de Santa Marta, in the department of Guajira, Colombia.
During the reproductive period, the males vocalize to attract the females, who accept the call and lay between 48 and 62 eggs in a gelatinous mass adhered to the leaves of the riparian vegetation.
The first description of the species was made on May 8, 2019, in the scientific journal PLOS One, by a group of nine Brazilian and Colombian researchers: Marco Rada, Pedro Henrique Dos Santos Dias, José Luis Pérez-Gonzalez, Marvin Anganoy-Criollo, Luis Alberto Rueda-Solano, María Alejandra Pinto-E, Lilia Mejía Quintero, Fernando Vargas-Salinas, and Taran Grant.
[1] It could be identified as belonging to the genus Ikakogi from morphological analysis, where it was observed: the white coloration of its bones, the transparency of the visceral and hepatic peritoneum and of the ventral anterior part of the parietal, the existence of a ridge-like structure in the center and along the humerus and the presence of humeral spines in adult males, as well as behavioral analysis, and the existence of parental care on the part of females.
[2] The first known sighting of the species occurred in 2015, when some of the authors of the description were on an expedition in search of frogs of the genus Atelopus and found an individual, which at first thought to be an I. tayrona, but with a different vocalization than expected.
[3] Subsequently, new expeditions were made in their search, with the holotype used for the study was found on October 1, 2016 in a small tributary of the Palomino River in the city of Dibulla, Colombia, at an altitude of 950 meters from sea level, and it was an adult male.
[2] Currently, the species has only been observed in two locations, always near some tributary stream of a larger river and at an altitude ranging from 850 to 950 meters above sea level, in the Sierra Nevada de Santa Marta, in the cities of Riohacha and Dibulla, in the department of Guajira, Colombia.
The texture of its skin is smooth on the back and granular on the belly, with the presence of a pair of large, rounded, flat tubercles on the lower thigh.
Its fingers are yellow, and the upper edge of its mouth and the side of the body are creamy-yellow, with a tiny line of white glazed dots on the flanks.
[2] They can only be distinguished from the tadpoles of I. tayrona by analyzing their internal morphology, where the number of lateral papillae on the mouth floor is counted, having thirteen in total, unlike this species that has ten.
[2] After the female chooses the males, they perform the amplexus, and then she lays her eggs in a single gelatinous mass on plant leaves hanging down toward the stream.
Their eggs, after hatching, give rise to tadpoles, which are usually found under sand or fallen leaves in puddles along the edge of the stream, with an area between one and two square meters and depth between thirty and fifty centimeters.
