Ropalidia is a large genus of eusocial paper wasps ( Polistinae) in the tribe Ropalidiini distributed throughout the Afrotropical, Indomalayan and Australasian biogeographical regions. The genus Ropalidia is unusual because it contains both independent and swarm-founding species. [1] Ropalidia romandi is one of the swarm founding species, meaning that new nests are founded by a large group of workers with a smaller number of inseminated females (egg-laying foundresses), [2] while Ropalidia revolutionalis is independent-founding, meaning that each nest is founded by a single foundress. [3]

Description

Ropalidia can be distinguished from other genera in the tribe by: the pronotum having a dorsal carina but lacking a pretegular carina, the first metasomal segment being petiolate but (in dorsal view) not parallel-sided, and the mesepisternum lacking a scrobal sulcus. [4]
