Abstract


The mangrove killifish Kryptolebias herma­phro­ditus is reported to the southeast and northeast regions of Brazil. Recently, a specimen of K. hermaphroditus was collected in a shallow running seawater stream at Ajuruteua beach, Pará state, northern Brazil. This new record is ca. 1,350 km from the nearest previously known occurrence in Rio Grande do Norte state, Brazil. Morphological, molecular, and ecological aspects of this species are described.


Keywords
