Rappole et al., 2005,
Naung Mung, Naung Mung Township, Kachin State, Union of Myanmar, elevation 540 m, 27°30’ N, 97°48’ E.
Given species rank in original description#R but treated as subspecies in HBW owing in part to mistaken claim of morphometric differences#R#R; however, single recording reveals a song or call very different from any recording of R. danjoui, involving a much higher maximum frequency (3), a rising whistle (pitch change 3) and shorter note length (ns), and this, combined with darker overall colour (1), stronger-marked moustachial and malar lines (1) and faint soft-edged ochreish vs well-defined brown-streaked breastband (2), returns the form provisionally to species rank (this may be forfeit if more recordings reveal that call or song scored above is shared by R. danjoui). Monotypic.
Naung Mung area of Kachin State, in N Myanmar.
