Abstract
Two new augochlorine genera, Chlerogelloides and Xenochlora, and three new Subgernera, Megalopta (Noctoraptor), Megommation (Stilbochlora), and Megommation (Cleptommation), are described and figured. Three new combinations are made: Megommation minutum (Friese), Xenochlora nigrofemorata (Smith), and Xenochlora ianthina (Smith). Six new species are described: Chlerogelloides femoralis, Xenochlora ochrosterna, Xenochlora chalkeos, Megalopta (Noctoraptor) byroni, M. (N.) noctifurax, and Megommation (Stilbochlora) eickworti. Megalopta (Noctoraptor) and Megommation (Cleptommation) are parasitic, possibly on other species of Megalopta and Megommation, respectively, and together increase the number or origins of cleptoparasitism in the tribe Augochlorini to three. For each genusgroup taxon, modified key couplets are provided for Eickwort's key to the genera of Augochlorini.
