| Resumo: |
Hydrometra argentina Berg, 1879, H. caraiba Guérin-Méneville, 1857 and H. guianana Hungerford & Evans, 1934 are newly recorded in the Amazon River floodplain, Brazil. A redescription of H. argentina is also given, as the original description is incomplete. A key to the three known species occurring in this region is provided. Hydrometra argentina can be distinguished from H. caraiba and H. guianana by the body length smaller than 12.50 mm, anteoculus/postoculus ratio between 1.80 and 2.00, clypeus narrow and conical, metacetabulum with no circular pits, and projections on male abdominal sternite VI in the shape of simple spines. The other species can be distinguished mainly by the anteoculus/postoculus ratio and position of projections on male abdominal sternite VI.
