Range DescriptionRecorded only from scattered localities in Angola, Democratic Republic of the Congo, Cameroon and Central African Republic. H. l. leucorhina occurs in the Democratic Republic of Congo southwards to northern Angola. H. l. cahni is known from Cameroon and Central African Republic. Variation in some dental characters (Bronner 1995) suggests that this taxon may include cryptic species.
