Type locality. Cameroun: “Alen”. Type depository: not traced.downgraded to junior synonym of C. semilutea by Evans (1937).

This is generally a larger subspecies (13.5–15.0 mm) that differs from the nominate in the stronger white forewing spotting, interposed between the two smaller subspecies. Normally there is an upper cell-spot, three subapical spots that are in line, and spots in 3, 2, and 1b, usually much larger than in the other subspecies. The hindwing has a broadly black costa and the yellow area is of a more insipid tone than in the nominate. The forewing underside has more subapical ochreous scaling than the nominate, though less than in ssp. congdoni. The hindwing underside shares the tone of yellowish-beige, lighter than on the upperside, and much less yellow than in the nominate. There is a brown patch at the end of the cell, another at the middle of space 1b, and one at the tornal angle (see figure 4). The hindwing underside is basically similar to ssp. congdoni; these two subspecies appear more closely related to each other than either is to ssp. semilutea .

There are records from the forests of Cameroun, Gabon, the Central African Republic, and westernmost parts of the Democratic Republic of Congo (Kinshasa), it must be in the Congo Republic as well. No Angolan material was located. There seems to be some degree of transition to ssp. congdoni between the Central African Republic and Kisangani, but hardly any material is available from that area.
