In recent years considered conspecific with K. signatus, although in earlier times the two were even placed in different genera. Molecular#R and morphological data support treatment as separate species, present form differing in its blue-grey (dark-tipped) vs blackish bill in male (3); overall slightly paler, plumbeous plumage in male (ns[1]); much brighter rufous uppertail-coverts in female (2); and much buffier wingbars in female (2). Described form “K. subflammulatus” now known to refer to immature male plumage of present species. Monotypic.
