Description
Summary:The Neotropical genus Phaedropus is revised, and two new species are described: Phaedropus inopinatus (type-locality, Bolivia, Santa Cruz) and Phaedropus suturellus (type-locality, Brazil, Mato Grosso do Sul, Água Clara). Keys and illustrations of habitus and male genitalia of the five known species are provided. Study of the male genitalia of Phaedropus disclosed a long flagellum inside the internal sac of median lobe. A brief study carried out on the male genitalia of the other four genera included in Entimini revealed that the flagellum is a feature unique of Phaedropus. In the genera Cydianerus Schoenherr, Entimus Germar, Polydius Schoenherr, and Rhigus Germar, the internal sac is provided with sclerites but lacks the flagellum.
