s. His main contributions have been: phylogenetic taxonomy of glassfrogs, description of the variation of skin texture in frogs, description of numerous species of amphibians and reptiles, and a monographic review of all Ecuadorian glassfrogs (60 species). A team led by Juan M. Guayasamin discovered '' Hyalinobatrachium yaku'' in May 2017, a glassfrog with transparent venter. To date (2020), he has described a total of 6 amphibian genera, 55 species of amphibians, and 11 reptiles, including two geckos from the Galápagos Islands.
