New records of Dipsas bucephala (Shaw, 1802) (Squamata, Dipsadidae, Dipsadini) from the Brazilian Central Plateau, with the first report from the Distrito Federal, Brazil

We report three new records of Dipsas bucephala (Shaw, 1802) from the Brazilian Cerrado, including the first confirmed from the Distrito Federal. Our records increase the number of confirmed localities in Goiás state from two to four and extend the known distribution by up to 350 km northeast, filling an important gap in the Central Brazilian Plateau. Most records were associated with gallery forests within the Cerrado matrix, highlighting the importance of riparian forest habitats as potential dispersal corridors for forest-associated species in open savanna landscapes.
