Taxonomic History
Significant nomenclatural changes have occurred in Metacyclini. Microbrotica was transferred from Metacyclini to Luperini (subtribe Diabroticina). Several formerly placed in other tribes have been reassigned to Metacyclini, including Cneorane nigripes to Metacycla. The tribe is part of ongoing taxonomic revisions of New World Galerucinae.
