Abstract
The male and female of Gynacantha vargasi sp. nov. are described from three sites on the Caribbean slope of Costa Rica. The species is distinguished from its congeners by lime-green lateral thoracic stripes, orange-brown hind femur tipped with black, dorsal side of the hind tibia yellow, unique cercus shape, diurnal behavior, and barcode analysis. A key to all species of Gynacantha recorded from Mexico and Central America is provided.

Gynacantha vargasi sp. nov.
Etymology. This species is named in honor of Ronald Vargas Castro, one of Costa Rica’s great naturalists, a
trusted companion who has accompanied me on many Odonata expeditions in Costa Rica and Ecuador and who has
collected numerous rare and undescribed species of Odonata, including two of the four known specimens of this
new Gynacantha.

Abstract: El macho y la hembra de Gynacantha vargasi sp. nov. se describen de tres sitios en la vertiente caribeña de Costa Rica. La especie se distingue de sus congéneres por sus franjas torácicas laterales de color verde limón, el fémur posterior de color marrón anaranjado con el ápice negro, lado dorsal de la tibia trasera amarillo, la forma única del cerco, su comportamiento diurno, y el análisis de código de barras. Se proporciona una clave para todas las especies de Gynacantha registradas de México y América Central.
