From Latin flabellum + -ate.
flabellate (comparative more flabellate, superlative most flabellate)
- (botany, zoology) Fan-shaped; having parts or segments that are flattened and lengthened on one side, such that they are long and narrow.
This term is used to describe the antennae of several kinds of beetles, where the last segments are shaped like a deck of cards. Flabellate antennae are a form of clubbed, or clavate antennae.
