The White-chested Tinkerbird is only known from a single specimen collected by Jali Makawa in 1964, from Mayau, Zambia. A lack of subsequent records of the species has led many authors to question the species' validity. However (Collar & Fishpool, 2006) provide good evidence that the two are in fact separate species since they diverge in at least 13 characters. Several searches have been mounted to try and rediscover this enigmatic species. However, though they have not met with success, the surveys have not been exhaustive, which leaves open the possibility that the species may still persist in the remotest parts of the Cryptosepalum forest in which it was collected.
