Equatorial Guinea on Numista map

The thread about Northern Marianas and Micronesia has made me examine the Numista map somewhat more thoroughly than I did in past. There are 2 dots indicating Sao Tome and Principe, a very small one off the coast of Cameroon and a larger one off the coast of the Rio Muni portion of Equatorial Guinea. I believe the small dot represents the island of Bioko, which is the insular part of Equatorial Guinea and that the large dot alone suffices for Sao Tome and Principe, as neither Sao Tome nor Principe is as far north as the dot off Cameroon, while Bioko is. As Bioko includes the Equatorial Guinea capital of Malabo, I think it definitely should be indicated as part of Equatorial Guinea on the map.
