Dussia atropurpurea is a new species found in Costa Rica and Panamá. It differs from all other Dussia species in this region in its dark purple sarcotesta. The only other species of Dussia with a sarcotesta of this colour is the Amazonian D. tessmannii which is clearly distinct morphologically. Sarcotesta colour is an important character for species delimitation in Dussia, but is infrequently recorded.
