Notes. There has been confusion regarding the correct name, publication date, identity, and limits of Gelastocoris flavus (Guérin-Méneville, 1835) and its two subspecies, G. f. flavus (Guérin-Méneville, 1835) and G. f. quadrimaculatus . For a summary, see Todd (1955), De Carlo (1959), Todd (1961), Nieser (1972), and Nieser (1975). The holotype and the allotype of G. bergi (= G. f. quadrimaculatus ) were originally deposited in the Institutos Científicos de San Miguel (Buenos Aires Province, Argentina) ( De Carlo 1954), whose collection was partially incorporated by the Instituto de Entomología de Salta (Salta, Argentina) ( Bachmann 1999), and finally by the Museo de Ciencias Naturales, Universidad Nacional de Salta (Salta, Argentina) ( von Ellenrieder 2009). However, De Carlo’s specimens are not mentioned in von Ellenrieder’s (2009) list of types of Insecta deposited in the Museo.
