Agaporomorphus julianeae sp. n. is described from the Biological Field Station Panguana, in Huanuco province of central Peru. The new species belongs to the A. knischi-group sensu Miller 2005. Together with A. knischi Zimmermann, 1921 and A. colberti Miller & Wheeler, 2008 this is the third species of the genus with broadly enlarged male antennomeres. The new species can be separated from A. colberti and A. knischi by the smaller please expanded male antennomere VIII, and the form of the median lobe. Important species characters (median lobe, male antennae, metafemur, colour pattern) of the new species and A. knischi are figured, and the habitat, a temporary blackwater forest pond, and its species rich water beetle coenosis are illustrated and described in detail. The Brazilian A. mecolobus Miller, 2001, only known from the type material from Sao Paulo, is here recorded for Minas Gerais. Habitus photos of four additional Agaporomorphus species and Hydrodytes opalinus (Zimmermann, 1921) are provided. Altogether ten species of Agaporomorphus are now known.
