Juan Manuel Guayasamin (born 1974) is an Ecuadorian herpetologist. He earned his Ph.D. in 2007 from University of Kansas, Department of Ecology and Evolutionary Biology and as of 2017 he is working as professor at Universidad San Francisco de Quito in Ecuador. His research interests include the evolution of glass frogs (Centrolenidae) and direct-developing anurans. His main contributions have been: phylogenetic taxonomy of glassfrogs, description of the variation of skin texture in frogs, and description of numerous species of amphibians and reptiles. A team led by Juan M. Guayasamin discovered Hyalinobatrachium yaku in May 2017, a glassfrog with transparent venter. [1]
