Kryptolebias sepia n. sp. is described from small forest tributaries of the Tapanahony and Palumeu Rivers which form part of the Upper Marowijne River system in southeast of Surinam. This species is distinguished from all other Kryptolebias spp. and Rivulus spp. by strong melanism on the body, its ability to change color pattern rapidly, the lack of strong sexual dimorphism, and the presence of pronounced adult/juvenile dichromatism.
