Hydatostega is a genus of
flies in the family
Dolichopodidae.[3] Most of its species are found in the
Americas, where it is mainly restricted to
montane habitats and high altitudes or latitudes, while three species are known from
Tristan da Cunha, a group of islands in the South Atlantic Ocean. Hydatostega was formerly considered a synonym of Hydrophorus, but was recently restored as a separate genus.[4]
