Abstract We investigated if differences in morphological characters in two species ofMetrodorea (Rutaceae) from Brazilian semideciduous forests correspond to some pollination divergence.M. nigra andM. stipularis are sympatric species, display a similar floral morphology, are protandrous, self-incompatible, their flower periods overlap, and both are pollinated by flies.M. nigra main pollinators arePseudoptiloleps nigripoda (Muscidae) andFannia sp. (Fanniidae);M. stipularis major pollinators arePhaenicia eximia (Calliphoridae),Palpada sp. andOrnidia obesa (Syrphidae). The distinct floral odor (disagreeable inM. nigra and sweet inM. stipularis) and color (brownish violet vs. pale yellow) determine the differences on type and number of floral visitors observed. Several species from semideciduous forests initially considered to be pollinated by diverse insects, present flies as main pollinators, stressing the importance of fly pollination in such habitats.
