Chauliooestrus Villeneuve, 1925 is revised and transferred from the Oestridae (Gasterophilinae) to the Sarcophagidae (Miltogrammatinae). Two species are recognised: C. denudatus (Villeneuve, 1921), which is recorded from Botswana, Malawi, Namibia, South Africa and Tanzania; and C. leza sp. n., which is descriptionbed on specimens from Botswana, Namibia and Zimbabwe. The male terminalia and cephalopharyngeal skeleton of the first instar larva of C. denudatus are descriptionbed for the first time, and C. leza is recorded as a parasite of the termite Hodotermes mossambicus Hagen.
