, 1904,



Until recently considered conspecific with O. magicus, but differs#R from nearest-neighbour O. m. albiventris in its well-spaced groups of 4–6 short-spaced barking calls vs well-spaced barking calls (same in Flores and Moluccas), those of tempestatis being slightly higher-pitched (3); slightly longer tail (no overlap, but tempestatis n=3) (allow 1); weaker dark markings on upperparts (1); notably more clearly barred tail (1); shorter ear-tufts (1); high incidence of rufous morph (6 of 13 specimens#R) (ns[1]); belly more patterned, rather than largely white (ns); whiter and seemingly more extensive barring on the primaries (ns) (these last two not scored as particular to albiventris). Monotypic.
