Abstract Pantophthalmidae (Diptera) are recorded exclusively in the Neotropical Region. Despite the large size of adults, their species are often rare and poorly represented in entomological collections. Only two genera and 20 species are known, of which 12 are recorded in the five regions of Brazil. In the North region, the family is reported from all states, except in Tocantins. The present work provides the first records of the family for Tocantins, expanding the distribution of two species, Pantophthalmus kerteszianus (Enderlein, 1914) and P. tabaninusThunberg, 1819. Both species are recorded for the first time in the Cerrado biome. In addition, we provide photographs of the species and a distribution map.
