World Catalogue of Insects is an initiative aimed at compiling worldscale, authoritative catalogues of monophyletic insect taxa.
Volumes will as a minimum contain standard nomenclatoral information on all names pertaining to the taxon treated, including type locality and distribution to the extent this is relevant.
Additional information is optional, e. g., location, status and condition of types; biology; bibliographical information; pest status; vector status; etc.
