Riodinidae is the family of metalmark butterflies. The common name "metalmarks" refers to the small, metallic-looking spots commonly found on their wings. The 1,532 species are placed in 146 genera. Although mostly Neotropical in distribution, the family is also represented both in the Nearctic, Palearctic, Australasian (Dicallaneura), Afrotropic, and Indomalayan realms.
Riodininae is the largest of the three subfamilies within the metalmark butterfly family, Riodinidae.
The Riodinini are one of the large tribes of metalmark butterflies. As numerous Riodinidae genera have not yet been unequivocally assigned to a tribe, the genus list is preliminary.
The Mesosemiini are one of the tribes of metalmark butterflies. They are the basalmost living tribe of the Riodininae, outside the main radiation together with the slightly more advanced Eurybiini.
The Nymphidiini are one of the larger tribes of metalmark butterflies. As numerous Riodinidae genera have not yet been unequivocally assigned to a tribe, the genus list is preliminary. The Theopina subtribe was formerly considered a distinct tribe Theopini.
The Eurybiini are a small tribe of metalmark butterflies. They are one of the basal tribes of the Riodininae, outside the main radiation but not quite as primitive as the Mesosemiini. Though numerous Riodinidae genera have not yet been unequivocally placed in a tribe and the genus list is thus preliminary, it is not very likely that many other genera will end up being assigned here.
