RESUMO
The genus Leptagrion Selys, 1876 comprises 17 described species. Of these species, only eight have their immature stage described. In this work, we describe the last instar larva of Leptagrion dispar Selys, 1876. The specimens were collected in areas of Atlantic Forest in three municipalities of the southern region of Bahia, Brazil, in phytotelmata habitats of bromeliads. Larvae were described based on the characteristics of the preserved F-0 larvae and exuviae of the emerged specimens in the laboratory. We added information about the habitats where the specimens were found. We extended occurrence records to other regions of the state of Bahia and presented a comparative table with morphological characteristics of all Leptagrion larvae already described.
