Closely related to C. atripennis, C. macrurus, C. manillensis and C. celebensis, and all five were formerly considered conspecific. Present taxon only recently separated from C. macrurus, from which it differs in its song being a quick series of a single, relatively weak, short “tyuk” (first note slightly farther apart from next than others), given in slightly longer but much faster runs than the deliberately spaced, loud, resonant “tyaunk” notes of macrurus (3); considerably smaller size, with proportionately shorter tail (wing 172–182, tail 125–130 vs 198–212, 156–172) (at least 2); blackish vs rufous-brownish mantle, and blackish vs rufous-buffy mid-belly with heavier barring (3); and proportionately smaller wing-spot (2)#R. It differs from the “adjacent” C. atripennis in its highly distinct song (see above) vs “a single loud, low-pitched, tremulous, musical CHEW dr’dr, first note clear, resonant, pealing and explosive, second much lower and hard, like a ball bouncing twice” (4); blackish vs chestnut-grey mantle (forming hindcollar in atripennis) and breast to belly (3); pure grey vs vermiculated grey crown (2)#R. Monotypic.

Distribution:

Andaman Is (probably all main islands and associated islets#R).
