• Inflorescences of the plant species serve as a breeding site for two very similar new species of Drosophilella, which are described in this paper. During a brief coexistence within the young inflorescence, females of both species oviposit and then depart. Although stamenicola oviposits among both staminate and pistillate flowers, pistilicola oviposits exclusively among the pistillate flowers at the base of the inflorescence. By the time the staminate portion has deliquesced and dropped off, it contains exclusively stamenicola larvae and puparia ; conversely, pistillate sections remain on the plant as the berries are formed ; they yield only pistilicola adults. Thus the strict subdivision of the floral niche is seen between the two species. Styloptera repletoides sp. n. oviposits on the inflorescences only after the decay processes are well advanced.
