Fossil gerromorphan bugs from the Cretaceous (Albian-Cenomanian boundary) amber of Charentes, SW France, are reviewed. A larva described by Perrichot et al. (2005) as incertae familiae within the Gerromorpha is now placed in the Mesoveliidae. Three new genera and species are also described and illustrated: Emilianovelia audax Solorzano Kraemer %26 Perrichot, gen. et sp.n., and Malenavelia videris Solorzano Kraemer %26 Perrichot, gen. et sp.n., which are placed in the Mesoveliidae: Mesoveliinae; and Arcantivelia petraudi Solorzano Kraemer %26 Perrichot, gen. et sp.n., which is the first Mesozoic member of the Veliinae. The relationships between these fossils and their palaeoecology are discussed. The new discoveries confirm the antiquity of the semi-aquatic gerromorphans, particularly the clade (Veliidae+Gerridae). The habitat is described as aquatic and likely marine-influenced, yet adaptation to a fully marine habitat in these gerromorphans remains difficult to establish.
