BACHMANN AND SILVIA A . MAZZUCCONI Gerridae is the second richest family of semiaquatic bugs in Argentina , with 18 described species in 11 genera. Andersen (1982) classified the Gerridae in eight subfamilies, of which Charmatometrinae , Cylindrostethinae , Gerrinae , Halobatinae , Rhagadotarsinae , and Trepobatinae are represented in the Argentinean fauna. Two tribes are currently recognized in the Gerrinae , following the classification proposed by Andersen (1995) : Gerrini and Tachygerrini , both of which are present in Argentina . The Halobatinae are classified in two tribes ( Andersen and Weir 2004 ), and only the Halobatini have been recorded from Argentina . Four tribes are currently recognized in the Trepobatinae ( Polhemus and Polhemus 2002 ) , of which only the Metrobatini and the Trepobatini are recorded from the country.
