Calliope (?) cruralis
Hitherto treated as conspecific with B. montana (and with the other six species now separated from this “parent”), but differs from morphologically and geographically closest B. sinensis in its much darker underparts in male (2); strong rufous lores and frons in female (2); only vaguely paler brown belly than rest of underparts vs clear whitish central belly (2); song of male rather longer, more warbled (at least 1)#R. Seemingly no evidence of intergradation with B. sinensis, but situation where these two approach or meet merits study. Monotypic.
