Valentibulla
Valentibulla is a genus of true fruit flies (Tephritidae) established by Foote & Blanc in 1959. The genus exhibits sexual dimorphism in which females are larger than males, but males possess enlarged forefemora used in mating. Male forefemur size predicts copulatory success. The genus is part of the diverse tephritid radiation, though detailed biological information remains limited.
