Monolepta is a genus of skeletonizing leaf beetles in the family Chrysomelidae. It is the most diverse and widely distributed genus in the Galerucinae sensu stricto, with more than 700 described species occurring almost worldwide. It is missing from the Nearctic realm.
The genus was first established by Louis Alexandre Auguste Chevrolat in 1836 to include species of Galerucinae with an elongated basi-metatarsus (the first tarsomere of the hind leg). The generic name Monolepta is derived from the Greek μόνος (monos, meaning 'one') and λεπτός (leptos, meaning 'thin, slender'). In 1875, Félicien Chapuis established the supra-generic group "Monoleptites", which included other Galerucinae with an elongated basi-metatarsus. Other genera traditionally placed in this group include, for example, Luperodes, Candezea and Barombiella. The group "Monoleptites" was later found to be polyphyletic, as an elongated basi-metatarsus has evolved multiple times in the Galerucinae.
