The known distribution of the genus is expanded and ranges from northeastern Brazil to the far south of the country, as well as Bolivia and Paraguay. New diagnoses are provided for G. karugua Pett, Rubio & Perger, 2022, G. mazaxoides (Perger & Duprr, 2021), G. mboitui (Pett, 2021) and G. elsneri Pett, Rubio & Perger, 2022 and scanning electron microscopy images of the genus are provided for the first time.
