Vigors and Horsfield, 1827,
Paramatta, New South Wales, Australia.
Form sepulcralis (incorporating everetti, virescens, infaustus and, usually, C. aeruginosus aeruginosus is often treated as a distinct species on grounds of claimed morphological and vocal differences, but latter very slight#R; further, contention that it is sympatric with variolosus in Moluccas#R has been refuted#R; sometimes reckoned to be closer to C. merulinus. Several additional island races have been described, but are nowadays considered invalid. Proposed race obiensis (of Obi) may prove valid (and long-presumed occurrence of infaustus there is contested) but it may prove to belong to C. aeruginosus#R; recent survey of Obi reported 2–3 different forms of Cacomantis, and it seems likely that present species and C. aeruginosus may both occur, but further work required#R. Proposed form dumetorum (N Australia from Kimberley to NE Queensland) is regarded as a synonym of nominate race. Ten subspecies recognized.
Also breeds (probably sepulcralis or infaustus) in Tanimbar Is.
