Population justification: The species' population size has not been quantified. There are no confirmed records of this species since the holotype was collected in 1955, but its calls may have been recorded in a few places in central Africa over the past 30 years, although the allocation of these calls to C. prigoginei has not been confirmed. Urgent survey work is needed to search for the species and estimate its population size.

Trend justification: Unknown. The continued clearance of forest for cultivation and livestock-grazing (Omari et al. 1999) is causing degradation and loss of forest within the species’ suspected range (Global Forest Watch 2024, using Hansen et al. [2013] data and methods disclosed therein).  However since the species is known from only a single specimen, its range, habitat use and tolerances are wholly unknown, such that land cover cannot presently be used to predict possible trends.
