Closely related to C. poortmani. Very similar to and apparently sympatric with race alice of latter. Race ignotus sometimes considered synonymous with alice, or treated as a hybrid. Birds of Colombia have been separated as race acuticaudus, but regarded as doubtfully valid. Two subspecies recognized.
