Melasinae

Fleming, 1821

false click beetles

Melasinae is a of in the , containing approximately 15 and at least 30 described . The subfamily includes several tribes: Calyptocerini, Ceballosmelasini, Dirhagini, Epiphanini, Hylocharini, Melasini, Neocharini, and Xylobiini. Genera within Melasinae include Melasis, Hylis, Epiphanis, Xylophilus, and Isorhipis. Some species, such as Hylis olexai, have established in the Nearctic region after originating from Western and Central Europe.

Taxonomic composition

BioLib recognizes eight tribes within Melasinae: Calyptocerini, Ceballosmelasini, Dirhagini, Epiphanini, Hylocharini, Melasini, Neocharini, and Xylobiini.
