General distribution. Cameroon, Democratic Republic of Congo, Ethiopia, Guinea, Kenya, Madagascar, Mauritius, Mozambique, Namibia, Niger, Nigeria, Rodrigues Island, Réunion, Senegal, Seychelles, Somalia, South Africa, Tanzania, Uganda (Yu et al. 2016), Yemen (including Socotra) (van Achterberg 2011), Saudi Arabia (new record).

Remarks. This is the first record of C. luteum for the Saudi Arabian fauna. It was previously recorded from Yemen by van Achterberg (2011). Although the Saudi Arabian specimen is somewhat lighter, this species agrees with Coccygidium luteum in van Achterberg’s key to the Arabian species (2011, couplet 3, p. 314) and van Achterberg’s plates 56–64.
