Chalcosicya maya, new species, (Coleoptera: Chrysomelidae: Eumolpinae) is described and the species
key of Blake (1951) is modified to accommodate it. This is the first known mainland species of this previously
Antillean genus. Sclerotized rods in the apical segment of the ovipositor of Chalcosicya Blake and related genera
are shown to be useful systematic characters within the eumolpine tribe Adoxini. Relationships with other genera
suggest that Chalcosicya belongs to a clade derived from ancestors with a western Tethyian distribution.
