The size of anomalines ranges between 5 and 40 mm, and their coloration has a wide range of tones, including metallic green, testaceous, and black. The characteristics are: labrum horizontally produced with respect to the clypeus; antennae with 9 segments; protibiae bidentate (rarely unidentate or tridentate), inner protibial spur subapical (lacking in Leptohoplia); foretarsomeres not enlarged or densely setose ventrally; elytra with membranous border at lateral margin; terminal spiracle not positioned in pleural suture.    
Classification Status

Blanchard (1851) first created the group name Anomalitae that included the genera Anisoplia, Tropiorhynchus, Callirhinus, Rhinyptia, Phyllopertha, Epectinaspis, Anomala, Mimela, Callistethus, Popillia, Pharaonus, Pachystethus, and Strigoderma. In 1886, Bates classified the group as a subfamily of Rutelidae. In 1902, Peringuey designated Anomalini as a tribe of Rutelinae and published a key to the tribes of Rutelinae of South Africa. Although members of this group are agriculturally important, there are few resources that allow for identification of the species in the New World. Paucar-Cabrera (2003) provided a key to all New World genera and conducted a phylogenetic analysis of some genera with an emphasis on the genus Epectinaspis. Publications with the taxonomic information about Anomalini are the Coleopterorum Catalogus (Ohaus 1918; Machatschke 1972), the Genera Insectorum (Machatschke 1957), and Blackwelder's (1944) checklist.
The tribe Anomalini in the New World includes 17 genera and about 310 described species. In the New World, anomalines occur from southern Canada to southern South America. Species of the tribe inhabit almost every habitat of the New World except the high Andes of South America.
