This is the second of three volumes covering species historically treated as 'Pyralidae', but now divided between the fuperfamily Thyridoidea and the families Pyralidae and Crambidae in the superfamily Pyraloidea. This volume encompasses all subfamilies in the Crambidae, except for the latter half of the Spilomelinae genera. In this volume the authors document 452 named species and 386 unnamed morphotypes. The volume does not serve as formal monograph describing species and revising genera. Instead, it acts as preliminary guide with the aim of encouraging the taxonomic community to undertake the formal descriptions and revisions. A significant proportion of the species included are economically important pests of rice, fruit, and stored products.
