Discussion: Previously considered a disjunct population of D. marsupialis (see Cerqueira, 1985). The senior synonym is D. azarae Temminck, 1824 (see Hershkovitz, 1969); however, the name had been misapplied to D. albiventris for over 160 years. The name leucoprymnus Matschie, 1916, is a nomen nudum; longigilis Ávila-Pires, 1968, is an incorrect subsequent spelling of longipilis Miranda-Ribeiro.
