About the author
Very little biographical information was available in the sources I could confirm during this search, but Juan R. León is clearly associated with herpetology and is credited as the author of The Systematics of the Frogs of the Hyla rubra Group in Middle America.
That study was published in 1969 in the University of Kansas Publications, Museum of Natural History and focuses on the classification and distribution of tree frogs in Middle America. The work has remained accessible through library and public-domain listings, which suggests it continues to matter as a specialist reference in amphibian taxonomy.
Because reliable personal details were scarce, it is safest to remember him here through the work itself: a rigorous scientific contribution centered on frogs, taxonomy, and the biodiversity of the Neotropics.
