With approximately 270 described species placed in 40 genera, acalyptine flower weevils include dozens of species that are specialized pollinators of Cyclanthaceae (Panama hat palms) in the subfamily Carludovicoideae. In spite of their ecological importance, these weevils are poorly known in Colombia; in particular, no published records exist for the northern portion of the Central Colombian Andes (Antioquia). Here we present the first reports of cyclanth/weevil pollinator associations for this region, including predominantly new species in the genera Cotithene Voss (1 species), Cyclanthura Franz (3 species), Ganglionus Franz & O’Brien (2 species), Perelleschus Wibmer & O'Brien (1 species), Phyllotrox Schoenherr (1 species), Staminodeus Franz (1 species), and Systenotelus Anderson & Gómez (1 species). In addition, 11 species pertaining to at least two undescribed genera in the Phyllotrogina and Staminodeina are present in the region. The weevils were collected on the inflorescences of the cyclanth genera Asplundia Harling, Carludovica Ruíz & Pavón, Dicranopygium Harling, and Sphaeradenia Harling; on the arum genera Anthurium Schott and Xanthosoma Schott; and on inflorescences of the composite genus Espeletia Mutis ex Bonpland. Larvae of a new species of Perelleschus were collected on the infructescences of Carludovica palmata Ruiz & Pavón. The results confirm and expand our knowledge of cyclanth/weevil associations and signal the need for revisionary taxonomic studies of these weevils.
