Mesosemiini

The Mesosemiini are one of the tribes of metalmark butterflies (family Riodinidae). They are the basalmost living tribe of the Riodininae, outside the main radiation together with the slightly more advanced Eurybiini.

Genera
As numerous Riodinidae genera have not yet been unequivocally assigned to a tribe, the genus list is preliminary.

In each subtribe, the genera are arranged in phylogenetic sequence, from the most plesiomorphic to the most apomorphic.

Subtribe Mesosemiina
 * Eunogyra
 * Teratophthalma
 * Mesosemia
 * Leucochimona
 * Semomesia
 * Mesophthalma
 * Perophthalma

Subtribe Napaeina
 * Hyphilaria
 * Napaea - includes Cremna
 * Voltinia - includes Eucorna
 * Ionotus - formerly in Cremna
 * Hermathena
 * Ithomiola
