Abstract

The southern South American genus Brachysternus Guérin-Méneville is revised and now includes seven species: B. angustus (Philippi and Philippi), B. germaini (Ohaus) new combination, B. marginatus Germain, B. olivaceus Philippi and Philippi, B. patagoniensis Jameson and Smith new species, B. prasinus Guérin-Méneville, and B. spectabilis Erichson. The following species names are new synonyms of B. prasinus: B. vicinus Guérin-Méneville, B. sinuatifrons Germain, B. pubescens Germain, B. viridis Germain, B. dilatatus Germain, B. viridipes Ohaus, and B. hirtus Ohaus. The following species names are new synonyms of B. olivaceus: B. chloris Philippi and Philippi, B. riverae Germain, B. herbaceus Germain, and B. araucanicus Ohaus. The following names were incorrect: ‘‘ B. viridis Guérin-Méneville’’ ( lapsus calami), ‘‘ B. viridis Laporte’’ ( lapsus calami), ‘‘ B. viridis Solier’’ (incorrect author), and ‘‘ B. fulvescens Germain’’ (misapplication). Lectotypes are designated for the following names: B. araucanicus Ohaus, B. chloris Philippi and Philippi, B. dilitatus Germain, B. fulvipes Guérin-Méneville, B. hirtus Ohaus, B. marginatus Germain, B. obscurus Philippi and Philippi, B. olivaceus Philippi and Philippi, B. philippii Germain, B. pubescens Germain, B. riverae Germain, B. spectabilis Erichson, B. vicinus Guérin-Méneville, B. viridipes Ohaus, and B. viridis Germain. Neotypes are designated for B. germaini (Ohaus) and B. prasinus Guérin-Méneville. Keys to adults, diagnostic characters, descriptions, and distributions are presented.

Se revisó el género Brachysternus Guérin-Méneville. Este género, presente al sur de Sudamérica, ahora incluye siete especies: B. angustus (Philippi y Philippi), B. germaini (Ohaus) nueva combinación, B. marginatus Germain, B. olivaceus Philippi y Philippi, B. patagoniensis Jameson y Smith nueva especie, B. prasinus Guérin-Méneville, y B. spectabilis Erichson. Las siguientes especies son nuevos sinónimos de B. prasinus: B. vicinus Guérin-Méneville, B. sinuatifrons Germain, B. pubescens Germain, B. viridis Germain, B. dilatatus Germain, B. araucanicus Ohaus, B. viridipes Ohaus, y B. hirtus Ohaus. Los siguientes nombres son nuevos sinónimos de B. olivaceus: B. chloris Philippi y Philippi, B. riverae Germain, B. herbaceus Germain, y B. araucanicus Ohaus. Se encontró que los siguientes nombres son incorrectos: ‘‘ B. viridis Guérin-Méneville’’ ( lapsus calami), ‘‘ B. viridis Laporte’’ ( lapsus calami), ‘‘ B. viridis Solier’’ (autor incorrecto), y ‘‘ B. fulvescens Germain’’ (nombre aplicado incorrectamente). Se designaron lectotipos para los siguientes nombres: B. araucanicus Ohaus, B. chloris Philippi y Philippi, B. dilitatus Germain, B. fulvipes Guérin-Méneville, B. hirtus Ohaus, B. marginatus Germain, B. obscurus Philippi y Philippi, B. olivaceus Philippi y Philippi, B. philippii Germain, B. pubescens Germain, B. riverae Germain, B. spectabilis Erichson, B. vicinus Guérin-Méneville, B. viridipes Ohaus, y B. viridis Germain. Se designaron neotipos para B. germaini (Ohaus) y B. prasinus Guérin-Méneville. En este estudio se presentan claves para la identificación de adultos, caracteres diagnóstico, descripciones y distribuciones.
