Epilachna (genus) Chevrolat in Dejean, 1837
This genus is widely distributed, especially in tropical and subtropical areas. It contains more than 50 species of ladybug beetles. All are presumably plant feeders as larvae as well as adults, although the host plants of various species are still unknown. Several species are agricultural pests, above all the Mexican bean beetle, Epilachna varivestis, which attacks beans and soybeans in North America and Japan.
The genus is closely related to the genus Henosepilachna, but the last abdominal sternite is split longitudinally in the middle in females and is undivided in males (always undivided in Henosepilachna).
Currently, the following species have been entered into the system:
