Taxonomic notes on the genus Charterginus Fox, 1898 (Vespidae: Polistinae: Epiponini) with images of the type specimens and new occurrence records.

Charterginus Fox, 1898 is a neotropical genus of swarm-founding social wasps consisting of six species. Despite its ecological significance, there are limited studies on various aspects of these wasps. To address this, this study aims to provide a comprehensive comparative diagnosis for all Charterginus species, accompanied by high-quality images of the type material. Moreover, a distribution map incorporating both previous and newly recorded occurrences is presented, shedding light on the geographical range of these species. Through these efforts, we aim to enhance the knowledge and facilitate future research on Charterginus, ultimately contributing to a better understanding of swarm-founding social wasps.
