This recently recognised species is believed to have a small and declining population, although it is not as scarce as previously reported. Increased settlement has led to increased pressure on natural resources, and planned development projects could severely affect suitable habitat within its very small range, although its population is not regarded as severely fragmented or restricted to a few locations, hence it is classified as Near Threatened.

Spilornis minimus (Sibley and Monroe 1990, 1993) has been split into S. klossi with the remainder (i.e. nominate minimus) lumped with S. cheela (Sibley and Monroe 1990, 1993) following Rasmussen and Anderton (2005).
