This is a parasitoid Tachinid Fly. According to Animal Diversity Web, Rhachoepalpus immaculatus is a Tachinid Fly. Tachinidae is a large family with many similar looking individuals, so we cannot say for certain if your identification is correct to the species level, but you do have the family correct.
