Leposoma puk, a new species of the scincoides group is described from the Atlantic forests of southern state of Bahia, Brazil. The new species is characterized by a single frontonasal; elongate dorsal and lanceolate ventral scales arranged in diagonal rows; weakly striated or smooth scales on top of head; a longer than wide interparietal, with almost straight lateral margins; 17-18 pores; third supraocular the largest one, wider than long and clearly rectangular in shape; a suture between frontal and frontoparietal scales coincident with the middle of the third supraocular; and, a black pigmentation in the venter or along venter margins in males. The discovery of this new species, sympatric with Leposoma annectans, L. nanodactylus, and L. scincoides ranks the Atlantic Rainforest region of Southern Bahia first in species diversity for the genus. Zoogeography and speciation of Leposoma of the scincoides group are discussed.
