Senegalia polyphylla (DC.) Britton Rose (Fabaceae) fruits were collected directly from the soil in the Sinop region, Mato Grosso, Brazil. The emerged insects were identified as Stator aegrotus (Sharp, 1885) (Coleoptera: Bruchidae), and since this plant had not been registered as a host for this species of bruchid, this constitutes the first association record for both species. The damage caused to the seeds reached 35.4%, with the consumption of seminal tissues of 0.04530 g, which represents 55.63% of the weight of a seed. In the physiological evaluation of the seeds, it was found that 100% of the damaged seeds did not germinate.
