Chrysomelini is a tribe in the leaf beetle subfamily Chrysomelinae. There are over 150 described genera in Chrysomelini, variously arranged into subtribes, though the exact number and delimitation of these subtribes is a source of ongoing debate.[1]

This tribe unites the "typical" leaf beetles small to mid-sized beetles, usually with a rather rotund shape. Many Chrysomelini are among the most colorful beetles known, some rivaling jewel beetles with their shiny metallic iridescence. Other species are not metallic, but colored contrastingly; in some cases this is known or suspected to be aposematic coloration to warn insectivores that these beetles accumulate noxious chemicals from their foodplants. Some perhaps most notoriously the invasive Colorado potato beetle (Leptinotarsa decemlineata) are dangerous crop pests, while others are useful in biocontrol of invasive weeds.

Genera

[edit]
Ambrostoma koreana adults in winter quarters
Ceralces affinis from Diani Beach, Kenya
Mesoplatys cincta from Cape Skirring, Senegal
Oidosoma ornatum from Diani Beach, Kenya
Pterodunga mirabilis from Garradunga, Australia
Sclerophaedon orbicularis from Bad Berneck im Fichtelgebirge, Germany

In addition, a prehistoric genus Stenaspidiotus has been described from Dominican amber fossils of at least early Miocene age (15-20 mya).
