نبذة مختصرة : A new Neotropical genus of Cyrtoscydmini, Obesoconnus gen. n., is described to accommodate two new species: O. guy-anensis sp. n. (the type species of Obesoconnus) from French Guyana and O. mexicanus sp. n. from Mexico. The mor-phology of the new taxon is described and illustrated in detail, and its possible affinities to other Cyrtoscydmini are discussed. Despite external dissimilarities, the aedeagus of Obesoconnus highly resembles copulatory organs of Al-loraphes and Parastenichnaphes; all these genera share the basal pumping apparatus and apically located ostium with asymmetrical apical projections.
