A revision of the genus Eurymesosa Breuning, 1938 (Cerambycidae, Lamiinae, Mesosini).

A taxonomic revision and redescription of the genus Eurymesosa Breuning, 1938 are presented, including a key to species. Three of the five currently accepted species are considered valid: Eurymesosaventralis (Pascoe, 1865), Eurymesosaallapsa (Pascoe, 1866) and Eurymesosaziranzhiyi Yamasako & Lin, 2016. Three junior synonyms are proposed for E.ventralis: Eurymesosaalbostictica Breuning, 1962, syn. nov., Eurymesosaaffinis Breuning, 1970, syn. nov., and Eurymesosamultinigromaculata Breuning, 1974, syn. nov. Additionally, E.allapsa (Pascoe, 1866) is resurrected from synonyms of E.ventralis. Females of E.allapsa and E.ziranzhiyi Yamasako & Lin, 2016 are described for the first time.
