A forest species, found from eastern Nigeria to Cameroun, Guinée Équatoriale, R. Congo to eastern R. D. Congo. Seems to be associated with large watercourses.

Life History, Abundance, Activity, and Special Behaviors
The males call from branches close to slow-flowing streams. The voice consists of single calls with a peculiar acoustic quality caused by a large number of harmonics, and is similar to that of the sympatric L. notatus but of somewhat longer duration. The voice is very similar, possibly identical to that of the West African L. macrotis, which could be a strong argument for regarding L. macrotis and L. millsoni as subspecies of one species.
