Cyclanthaceae is a plant family that kind of looks like palms, but are unrelated. They are generally pollinated by beetles, and many of the species specifically by weevils. One the genera of weevils typically found in these flowers is Cotithene, but all species described to date do not seem to be pollinators, only florivores. They are not very abundant, their behavior does not synchronize with flowering times and they are too big to fit into the small spaces the lead to receptive female flowers. In this paper we describe a new species: Cotithene gorayebi, and also show that it is a pollinator of a cyclanth: Evodianthus funifer. This new species is smaller than other species of Cotithene, very abundant and comes and goes from flowers at the right timing to be a good pollinator.
