We present a survey of the semiaquatic bugs (Insecta, Heteroptera, Gerromorpha) from Ribeira de Iguape river basin, Vale do Ribeira, Sao Paulo state, Brazil. Six species of Gerromorpha had been previously recorded from the area based on isolated collection events, namely Oiovelia brasiliensis Moreira, Nessimian & Rudio, 2010, Rhagovelia accedens Drake, 1957, R. aiuruoca Moreira & Ribeiro, 2009, R. henryi Polhemus, 1997, R. lucida Gould, 1931, and R. trepida Bacon, 1948.
