Until recently considered a race of C. lepidus (which see), but molecular analysis suggests species status#R and this is supported by morphological evidence: present species differs from all other taxa formerly grouped under Variable Dwarf-kingfisher to the W of its range in its smaller size (effect size for wing compared with the relatively small lepidus −4.48; score 2), much narrower but equally long bill (not measured, but at least 1), black bill (3), deeper blue dorsum (2), buffy-whitish (and relatively small) loral spot (darker in all other taxa except gentianus) (allow 1); it differs from all taxa to the E and N in similar characters, but is closest to (a) meeki (including in size), from which it differs in much richer orange vs whitish-orange underparts (2), narrower and perhaps longer bill (1), continuous royal-blue upperparts and head sides vs pale turquoise-green spotting on black (3), smaller size (effect size for wing −2.94, score 2); and (b) mulcatus, from which it differs in smaller size (effect size for wing −4.85, score 2), much narrower but equally long bill (not measured, but at least 1), whitish, small vs rufous-buffy, large loral spot, and paler rufous underparts (2), and less turquoise, more royal blue on dorsal area (1). Monotypic.
