Mc Gough ; 2♂ ( USNM), Cameroon, Ottotomo Forest , 11 September 1951, leg. J.M. Mc Gough ; 1♂ 1♀ ( QMB), Democratic Republic of Congo, Sandoa , Katanga, 19 May 1931 ; 1♀ (Type of C. fenestratus oculatus Bezzi , RMCA), Democratic Republic of Congo, Maluku , 17 April 1912, leg. Mus. Tervuren, R. DET. 865, Dr. Mouchet ; 1♂ 1♀ ( TAUI), Nigeria, Plateau State, Kurra Falls , 60 km SE Jos, 5, 7 July 1987, leg. A.

Distribution. Angola, Cameroon, Democratic Republic of Congo, Equatorial Guinea, Kenya, Malawi, Nigeria, Zaire, Zambia, Zimbabwe.

Remarks. The wing markings of C. obnubilus are variable according to Hancock (1986). In our examination, various markings are also found in 2♂ 1♀ from Cameroon and 1♀ from Democratic Republic of Congo. However, because we only examined limited materials, keeping all specimens under C. obnubilus is accepted here.
