Tetramesa
Tetramesa is a genus of minute phytophagous wasps in the family Eurytomidae comprising over 200 described species. Members are exclusively associated with grasses (Poaceae), where they typically induce stem or inflorescence galls. The genus exhibits pronounced host specificity, with most species restricted to a single grass species or closely related congeners. Several species have been deployed as biological control agents against invasive grasses, including T. romana for giant reed (Arundo donax) and candidate agents for medusahead (Taeniatherum caput-medusae) and African lovegrass (Eragrostis curvula). Adults feed on nectar. Recent phylogenomic studies have synonymized the genera Aiolomorphus and Cathilaria within Tetramesa.
