The author revalidates the genus Sarcopromusca Townsend, 1927 including two species: S. pruna (Shannon & Del Ponte, 1926) and S. sarcophagina (Wulp, 1896). The former is herein redescribed with illustrations and known geographical distribution. A key to distinguish Morellia Robineau-Desvoidy, 1830, Orthellia Robineau-Desvoidy, 1830, Pyrellia Robineau-Desvoidy, 1830 and Sarcopromusca Townsend, 1927 is also presented.
