It is found in Costa Rica, where it is only known from the eastern slopes of the Cordillera Volcanica de Guanacaste, Cordillera Volcanica Central, Cordillera de Talamanca, llanuras de Sarapiqui, and the lowlands of the Caribbean, at elevations ranging from 50 to 1,115 meters.

The forewing dorsal ground color is cream at the base and 2/3 black brown.

The dorsal hindwing is dirty gray brown, but lighter near the base.

The species is named in honor of Ms. Jessie Barron, great-great-grandmother of Jessie Hill of Philadelphia and Hawaii, in recognition of Jessie Hill's contribution to saving and inventorying the conserved ACG rain forest in which Dunama jessiebarronae breeds.
