Résumé : Sexual dimorphisms in four related species of tephritid flies were shown to be associated with differences in sexual behavior. In two species, Ceraritis capitata and C. catoirii, males and females approach closely head to head and apparently· touch aristae, and the male buzzes his wings, probably Canning pheromone toward the feroale; the males were found to have longer aristae with fewer microsetae, and larger posterior areas of their wings than do females. These dimorphisms were absent in the other two species. C. rosa and Neoceratitis cyaneseens, which court at a longer distance and in which the male does not fan pheromone toward the feroale priar to mounting. AlI three pairs of legs were proportionally longer in the males of aIl four species. None of the other sexually dimorphic male signalling traits showed the positive a110metric slopes predicted by sorne theories.
